Igf-1 Info good reading!!!!!
IGF1, also known as somatomedin C, is polypeptide hormone about the same size as insulin. It is produced predominantly in the liver in response to growth hormone (GH) release from the pituitary gland. Many of the growth promoting effects of GH are due to its ability to release IGF1 from the liver. The conversion ratio of GH to IGF1 varies greatly in different individuals but most external sources of GH convert around 4-6mcg of IGF per one I.U. of GH. IGF-1 acts on several different tissues to enhance growth. IGF1 belongs in the 'superfamily' of substances known as 'growth factors,' along with epidermal (skin), transforming; platelet derived fibroblast, nerve, and ciliary neurotrophic growth factors. None of the other factors have any bearing on exoskeletal tissue incidentally however These agents all have in common the ability to stimulate cell division, known as mitogenesis, and cell differentiation. Meaning That In the case of IGF1 which does act on muscle tissue it will initiate the growth of new muscle fibers, and subsequently new receptors for testosterone. Users have unanimously concluded that it enhances cycles of steroids significantly. They also seem to be adamant about its ability to reduce fat and improve vascularity a great deal.

The IGF1 Hype

There is a considerable amount of hype surrounding IGF1. Every one is blaming the distended bellies of modern Bodybuilders on it. Also the freaky proportions that old bodybuilders that have been around for years are starting to attain. Anti-aging proponents are touting it as the miracle cure for every thing from Parkinson's disease to Alzheimer's. And the medical community has published numerous articles on it for its ability to cause cancer, diabetes and gigantism. While at the same time performing documented experiments on thousands of patients of muscle wasting diseases. And reporting significant turnabouts in there conditions. So what is a guy to think about IGF1 as far as athletic enhancement is concerned? Well first of all you need to know that most experiments conducted with IGF1 do not list the type of IGF used. I have written Dr. Robert Saline of the Swedish rejuvenation institute on several occasions and we have had in-depth discussions on the subject of IGF1 for physical appearance enhancement. He feels it would be unethical to prescribe IGF1 to a bodybuilder to increase muscle mass simply due to the fact that IGF1 has valid applications in the medical community, (Like I could give a rats ass about "ethical"). He can not argue that it is extremely effective as a promoter of muscle growth far beyond what androgens (steroids) alone can offer. Well fortunately in America IGF1 is not a drug (yet) and the FDA has no control over it as of now. This will change in the very near future however, Im absolutely sure of it.

How to use IGF1

Assuming that you have acquired legitimate IGF1 (R3) long chain, That's IGF1 with the binding protein added. You should take dosages ranging from 60mcg up to 120mcg per day in divided doses. One injection in the morning and again at bed time. Never exceed 120mcg in one day. IGF1 can cause serious gastrointestinal problems such as tumors intestinal swelling diarrhea and vomiting. Most IGF1 comes in a concentration of 1000mcg per ML or CC so it makes it easy to measure in an insulin syringe. 10 IU on the syringe is 100mcg. Do the math.

IGF + Insulin

If you plan on doing IGF1 with Insulin, listen closely IGF1 is not that expensive, sure you can get away with using less by including insulin in the stack, but IGF1 and Insulin together have a pro-insulin effect on your blood sugar balance. It can enhance the chances of a hypoglycemic episode ten fold. I would recommend against it for any one not ABSOLUTLY comfortable with insulin or IGF1.

Here is how insulin and IGF1 work together. Igfbp3 is the binding protein, which allows IGF1 to remain active in the system for a long enough period of time to really work its magic. IGF1 by nature has a half-life of less than 10 minutes by its self. The molecule was so small it would escape the blood stream very rapidly. This was the reason IGF1 was so "underground". It took very frequent injections at high dosages to achieve even minimal results. Aside from this reconstituting the compound required a degree in biochemistry. This short acting version was the only IGF1 known until recently IGF1 would have been administered in 100 mcg dosages 4-6 times a day. That is a hell of a lot of IGF1. That explains a lot of the distended bellies. Now with R3 long chain IGF1 and the Binding protein IGFBP3 IGF1 will last up to 6 hours in the system. By binding IGF to the IGFBP3 you make the molecule larger and it gets trapped in the blood stream until the protein is broken down and the IGF molecule escapes. You can further its life by combining Insulin with it, although I here its very risky. Insulin prevents the breakdown of IGFBP3 and leaves the IGF1 molecule roaming free in the blood stream for longer periods of time up to 12 hours as insulin levels return to normal IGFBP3 will begin to break down and the IGF1 will escape from its bound protein IGFBP3 again having a half life of less than 10 minutes.

Insulin should be taken at the normal dosage it is usually administered at minus 10% about 45 minutes prior to the IGF1 infusion. Again let me remind you this can be deadly if you don't know what you are doing. And of course do not use Insulin for the nighttime injection of IGF1 by taking it in the morning you prolong the IGF1's half life to 12 hours and then take a 6 hour injection, you should be fine. Hell if you want to eat a big bowl of rice and drink another 100g of simple carbs 45 minutes before the bed time IGF1 infusion you could spike insulin for at least a few hours of extended IGF1 activity. If your not going to be using insulin in the stack then go ahead and do the same in the morning.

What users report

Users of IGF1 have reported various results but all along the same lines, It does not appear to be dramatically less effective in any one individual (at least not to the best of my knowledge). I have a good friend who had to stop taking IGF1 due to stomach illness that was completely unrelated But he to experienced good gains from it for the 2 weeks he was on it, his dosage was 120mcg per day. One hour after the first injection he went to the gym and immediately told me about the uncontrollable pump he got from just one set.

That would indicate to me that he was experiencing some form of cell volumization. The general consensus on IGF1 seems to be that its benefits are as fallow:

Increased Pump Pumps are reported to be so severe that workouts are often cut short due to lack of ability to the muscle through the full range of motion...ouch

Gains retention is increased if IGF is used in a cycle I am not sure why, but IGF1 seems to make gains on a cycle stick with virtually no post cycle loss. Every bodybuilder I've spoken with seems to think this for some reason. Most of them use drugs like Anadrol or Dianabol with it because of the amount of size attained with these drugs. The usual draw back to these drugs is that in most users there is a post cycle "crash" that occurs, so the reasoning is to toss IGF1 into the stack and grow larger faster with out the post cycle crash blues.

Reverses testicular atrophy

Testicles if shrunken will return to "full swing" so to speak even in the middle of a cycle. If not shrunken they will not shrink during the cycle. This may explain partially why gains are kept after the cycle.

Fatigue

Users report feeling drained and tired all day. This seems to be one of the negative side effects to IGF1, it will make you sleep longer and you will require more sleep at night to feel rested for the morning. This is common with high doses of HGH and exhibited in children, whose IGF1 levels are extraordinarily high. A child needs 4 hours more sleep than an adult on average does. This may be directly or indirectly related to IGF1 levels.

Stiffness

An almost arthritic feeling is commonly associated with high levels of HGH, well IGF1 has the exact same property. IGF1 will cause your hands, fingers and knuckles to ache this is one way you can be sure you got real IGF1.

IGF-1's Side effects

Every thing has a down side. To bake a cake ya gotta brake an egg. IGF1 is no exception. The drug used in larger quantity around the 100mcg+ range will cause headaches, occasional nausea and can contribute to low blood sugar or hypoglycemia in some users. Although I have never heard of this first hand I'm sure its true.

IGF1 will attach its self to the lining of the intestine and cause atrophy of the gut. Every thing IGF1 touches will grow and you have a lot of receptors on the lining of the large intestine and inner wall of the abdominal well. This is what causes the GH gut look. You can easily avoid this by limiting your dosages and cycle lengths. IGF1 cycles should be kept to 4-6 weeks with 4-6 weeks off in-between. IGF-1 is considerably more powerful than HGH and you need to think of it along those lines as far as dosing goes. We all know what to much HGH can do over prolonged periods of usage. The Neanderthal look is definitely not going to win any shows this year. I would recommend 80 mcg a day for 4 weeks at a time you should get good results from that for a while. I don't know if you will need to up the dosage at any point, but I would think in the case of IGF1 it wouldn't matter. If 80mcg doesn't do it for ya, then bump it up to 100 You should definitely feel it at this point If not suspect the IGF1 as being fake. Beyond 120 mcg per day your asking for trouble, This compound demands as much respect as its sister amino Insulin.

Clinical Facts about IGF-1

IGF-1 is a polypeptide of 70 amino acids (7650 daltons), and is one of a number of related insulin-like growth factors present in the circulation. The molecule shows approximately 50% sequence homology with proinsulin and has a number of biological activities similar to insulin. IGF-1 is a mediator of longitudinal growth in humans or how tall you are capable of becoming. Serum IGF-1 concentrations are altered by age, nutritional status, body composition, and growth hormone secretion. A single basal IGF-1 level is useful in the assessment of short stature in children and in nutritional support studies of acutely ill patients. For the diagnosis of acromegaly, a single IGF-1 concentration is more reliable than a random hGH measurement (Oppizi, et al., 1986). IGF-1 can be used for the assessment of disease activity in acromegaly (Barkan, et al., 198.

Almost all (>95%) of serum IGF-1 circulates bound to specific IGF binding proteins (IGFBPs), of which six classes (IGFBPs 1-6) have been identified (Rudd, 1991). BP3 is thought to be the major binding protein

IGF 1 INFO GOOD READING

Good article my friend, we dont hear much about IGF-1 where I live (nz) growth yes, If IGF-1 not scheduled in the usa, where can you get it? or do you still have to go the blkack market route? I Could legally bring some in under a certain section in our scheduling laws, but even my doc cant find a pharmaceutical company who can front it. Any suggestions any one?:confused:

What's the difference in Receptor Grade (RG) and Media Grade (MG)...other than price?
Long R3 IGF-1
5mg RG = $5850 US
5mg MG = $650 US

BTW...
It's in Phase II of development here in the US
SomatoKine®

SomatoKine® is the recombinant protein complex of insulin-like growth factor-I (IGF-I) and its most abundant binding protein, insulin like growth factor binding protein-3 (IGFBP-3). SomatoKine displays metabolic and anabolic activities similar to those observed with recombinant IGF-I (rhIGF-I). IGF-I elicits many of the physiological effects of insulin, which are mediated through a specific cell surface receptor. IGF-I is a small polypeptide with strong structural and functional homology to pro-insulin. Of striking importance, SomatoKine has a longer half-life and has demonstrated an improved safety profile compared to rhIGF-I.
In healthy individuals, IGF-I is constantly present in the bloodstream. In the circulation, IGF-I is bound to IGFBP-3, and forms a large ternary 150kD complex after association with acid-labile subunit protein (ALS). The ternary complex is restricted to the circulation by the capillary endothelium and thus serves as a circulatory reservoir of IGF-I.

SomatoKine® continues to be studied as part of a broad clinical development program designed to provide information about its efficacy and safety in diverse patient populations and in a variety of unmet medical needs, including, but not limited to, GHIS, diabetes, and severe burn injuries.

IGF-1 R3

IGF1 stands for insulin like growth factor. It mimics insulin in the human body and also at the same time makes the muscles more sensitive to insulin’s effects. It is a growth factor and is the most potent one in the human body at that. IGF causes muscle cell hyperplasia, which is an actual splitting and forming of new muscle cells. This was thought to only be possible during puberty. IGF is much more potent at this effect than growth hormone is, in fact almost all of the effects you see from growth hormone come from the increased amount of IGF that your liver produces when the GH is destroyed. So it would be very easy to say that IGF is a much more potent and cheaper alternative to GH use, although GH is more effective for fat loss than IGF due to some other effects that it causes such as metabolism increase and the ability to effectively use more insulin, T3, and anabolic steroids.

Another advantage that IGF has over GH is that it has much more of an affinity to attach to muscle cells instead of bone and organ cells. Growth hormone has been know to cause a lot of organ enlargement and bone elongation since it attaches to all types of receptor cells. IGF is much more likely to go where we want it, our muscle cells. IGF-1 attaches to myogenic stem cells which are only located in muscle and connective tissues. These myogenic stem cells are responsible for the production of myoblast cells which in turn are responsible for the buildup and repair of connective tissues (ligaments, tendons, cartilage, and joints to a certain extent).

So from this you can see that IGF-1 is great for increasing the strength of tendons and also for helping to heal existing injuries while at the same time helping to prevent them. IGF-1 is also responsible for increased protein synthesis and amino acid synthesis.

IGF does not have to be used along with anabolic steroids, GH, insulin, or thyroid hormones to be effective. It causes muscle growth on its own. In fact some people prefer to use it during their breaks from steroid cycles since IGF has no effect on natural test production. It could effectively be used along with HCG, clomid, and PGF2a for a hell of an off cycle stack which would allow your body to return to normal and still allow you to grow!! On its own IGF will give an increase of around 2 lbs. of new solid lean muscle tissue every two weeks, and is also is know for its ability to strip off body fat and GREATLY increase vascularity, body fat decreases of 5-8% over a 50 day cycle are not uncommon. But, of course you will be much happier with the results if you use the IGF along with anabolic steroids, testosterone, and insulin.

The use of steroids along with the IGF allow you to quickly mature and strengthen the new muscle tissue that the IGF has formed, and may also speed the process of hyperplasia. If you need any help setting up a great stack to
use along with the IGF just let me know and I can help you out. I speak with lots of top bodybuilders and guru’s so I am very knowledgeable.

The dosage issue for IGF is where the most controversy lies. Dosages used by competitive athletes most commonly range anywhere between 60mcg/day to 100+mcg/day. The trick is finding the dosage that works best for YOU. For most the best results appear when you reach a dosage of 80mcg/day, while some do
receive good results from only 40mcg/day. I personally feel the best results begin to be noticed at a dosage of 100mcg/day. I personally am using 150mcg/day during my current cycle.

Also I should let you know that the form of IGF is the Long R3 analog. It has been chemically altered and has a longer half-life than regular IGF, which only lasts about 10 minutes in the human body once injected. The Long R3 IGF-1 has a half-life of 6-10 hours, so you will only need to inject once or twice per day. The best time to inject is after lifting and in the morning, so it would be best to use half the dosage in the morning and the other half after lifting. This will take maximal advantage of IGF’s insulin
mimicking effects.

From Scorpio @ MC -
IGF-1: How does it work?

To understand how IGF-1 works you have to understand how muscles grow. The ability of muscle tissue to constantly regenerate in response to activity makes it unique. It’s ability to respond to physical/mechanical stimuli depends greatly on what are called satellite cells. Satellite cells are muscle precursor cells. You might think of them as "pro-muscle" cells. They are cells that reside on and around muscle cells. These cells sit dormant until called upon by growth factors such as IGF-1. Once this happens these cells divide and genetically change into cells that have nuclei identical to those of muscle cells. These new satellite cells with muscle nuclei are critical if not mandatory to muscle growth.

Without the ability to increase the number of nuclei, a muscle cell will not grow larger and its ability to repair itself is limited. The explanation for this is quite simple. The nucleus of the cell is where all of the blue prints for new muscle come from. The larger the muscle, the more nuclei you need to maintain it. In fact there is a "nuclear to volume" ratio that cannot be overridden. Whenever a muscle grows in response to functional overload there is a positive correlation between the increase in the number of myonuclei and the increase in fiber cross sectional area (CSA). When satellite cells are prohibited from donating new nuclei, overloaded muscle will not grow (Rosenblatt,1992 & 1994; Phelan,1997). So you see, one important key to unnatural muscle growth is the activation of satellite cells by growth factors such as IGF-1.

IGF-1 stimulates both proliferation (an increase in cell number) and differentiation (a conversion to muscle specific nuclei) in an autocrine-paracrine manner, although it induces differentiation to a much greater degree. This is in agreement with the Dual Effector theory. In fact, you can inject a muscle with IGF-1 and it will grow! Studies have shown that , when injected locally, IGF-1 increases satellite cell activity, muscle DNA content, muscle protein content, muscle weight and muscle cross sectional area (Adams,1998).
On the very cutting edge of research scientists are now discovering the signaling pathway by which mechanical stimulation and IGF-1 activity leads to all of the above changes in satellite cells, muscle DNA content, muscle protein content, muscle weight and muscle cross sectional area just outlined above. This research is stemming from studies done to explain cardiac hypertrophy. It involves a muscle enzyme called calcineurin which is a phosphatase enzyme activated by high intracellular calcium ion concentrations (Dunn, 1999). Note that overloaded muscle is characterized by chronically elevated intracellular calcium ion concentrations. Other recent research has demonstrated that IGF-1 increases intracellular calcium ion concentrations leading to the activation of the signaling pathway, and subsequent muscle fiber hypertrophy (Semsarian, 1999; Musaro, 1999). I am by no means a geneticist so I hesitated even bringing this new research up. In summary the researchers involved in these studies have explained it this way, IGF-1 as well as activated calcineurin, induces expression of the transcription factor GATA-2, which accumulates in a subset of myocyte nuclei, where it associates with calcineurin and a specific dephosphorylated isoform of the transcription factor nuclear factor of activated T cells or NF-ATc1. Thus, IGF-1 induces calcineurin-mediated signaling and activation of GATA-2, a marker of skeletal muscle hypertrophy, which cooperates with selected NF-ATc isoforms to activate gene expression programs leading to increased contractile protein synthesis and muscle hypertrophy. Did you get all that?

From Scorpio @ MC - (kinda shows something bout the strength)IGF-1 Once Again Proves to be One of the Most Powerful Mediators of Muscle Growth-by Bryan Haycock, MS, CSCS
Viral mediated expression of insulin-like growth factor I blocks the aging-related loss of skeletal muscle function
Researchers:
Elisabeth R. Barton-Davis*, Daria I. Shoturma*, Antonio Musaro, Nadia Rosenthal, and H. Lee Sweeney*,
* Department of Physiology, University of Pennsylvania School of Medicine, Philadelphia, PA and Cardiovascular Research Center, Massachusetts General Hospital, Charlestown, MA
Source:
Proc Natl Acad Sci U S A 1998 Dec 22;95(26):15603-7
Summary:
Although the mechanisms underlying age associated muscle loss are not entirely understood, researchers attempted to moderate the loss by increasing the regenerative capacity of muscle. This involved the injection of a recombinant adeno-associated virus directing overexpression of insulin-like growth factor I (IGF-I) in differentiated muscle fibers.

They demonstrated that the IGF-I expression promotes an average increase of 15% in muscle mass and a 14% increase in strength in young adult mice (Figure 1), and remarkably, prevents aging-related muscle changes in old adult mice, resulting in a 27% increase in strength as compared with uninjected old muscles (Figure 2). Muscle mass and fiber type distributions were maintained at levels similar to those in young adults. These results suggest that gene transfer of IGF-I into muscle could form the basis of a human gene therapy for preventing the loss of muscle function associated with aging and may be of benefit in diseases where the rate of damage to skeletal muscle is accelerated.

Discussion:
I’m not sure where to begin. This study has the potential to completely change the way we age.
In this experiment, a recombinant adeno-associated virus, directing overexpression of insulin-like growth factor I (IGF-I) in mature muscle fibers, was injected into the muscles of mice. The DNA that was originally in the virus was removed along with markers that stimulate immune response. DNA coding for IGF-1 was then put into the virus along with a promoter gene to ensure high rates of transcription. The results, as you can see by figures 1 & 2, were dramatic.
IGF-1 plays a crucial role in muscle regeneration. IGF-1 stimulates both proliferation and differentiation of stem cells in an autocrine-paracrine manner, although it induces differentiation to a much greater degree. IGF-1, when injected locally, increases satellite cell activity, muscle DNA, muscle protein content, muscle weight and muscle cross sectional area. The importance of IGF-1 lies in the fact that all of its apparent functions act to induce muscle growth with or without overload although it really shines as a growth promoter when combined with physical loading of the muscle.
IGF-1 also acts as an endocrine growth factor having an anabolic effect on distant tissues once released into the blood stream by the liver. IGF-1 possesses the insulin-like property of inhibiting degradation, but in addition can stimulate protein synthesis. The insulin-like effects are probably due to the similarity of the signaling pathways between insulin and IGF-1 following ligand binding at the receptors.
The ability of IGF-I to stimulate protein synthesis resembles the action of GH, which was shown in separate studies on volunteers to stimulate protein synthesis without affecting protein degradation. Although it is often believed that the effects of GH are mediated through IGF-1, this cannot be the case entirely. First, the effects of the two hormones are different, in that GH does not change protein degradation. Second, the effect of GH is observed with little or no change in systemic IGF-1 concentrations. Age related muscle loss has been prevented with GH injections, however it is believed that this is accomplished through IGF-1.
The results of this study are similar to other studies where IGF-1 was injected directly into muscle tissue, resulting in increases in size and strength of experimental animals. Using a virus as a genetic vehicle has an advantage over simply injecting the growth factor. The effects of a single viral treatment last significantly longer (months if not years) because the muscle cell itself is constantly overproducing its own IGF-1 from injected DNA.
The fact that the IGF-1 produced by the muscle of these mice did not reach the blood stream is interesting. Systemic injections of IGF-1 have not been successful in inducing this kind of anabolic effect in humans. In addition, IGF-1 produced by the liver is genetically different than that produced by muscle tissue. It could be that providing additional DNA for the muscle to produce it’s own IGF-1 is the key to achieving anabolic and rejuvenative effects specifically in skeletal muscle.
In this study there was a preferential preservation of type IIb muscle fibers in aging mice. These are the fibers most sensitive to muscle hypertrophy from training and they are also the first fibers to disappear with aging. In the mice receiving the engineered virus, there was also a preservation of the motor neuron, leading to an increase in functional capacity. It is speculated that age related muscle loss is secondary to the loss of neuronal activation of type-II fibers. By preventing the degeneration of typ-II motor units, functional capacity could be maintained into old age. This technique may also serve useful in the prevention of osteoporosis. Further study is necessary to determine wether IGF-1 is having an effect only on muscle fibers or on nervous tissues as well.
Finally, it was also exciting to see muscle growth in the young mice who received the injection (15% increase in muscle mass). This means that the injection provided levels of IGF-1 far and above what the muscle normally has access to and not simply a preservation of normal levels. Remember that this was not combined with exercise. The growth of the injected muscles happened even without an extreme mechanical stimulus. The mice were simply allowed to run around as they usually do. Because of these dramatic results, the authors expressed concern about the use of this technique to enhance performance or cosmetic appearance. Research Update is not my personal soap box so I won’t go off on the gender centered hypocrisy of cosmetic enhancement in our society. All we can hope for is that this technique will be used to treat more important diseases such as muscular dystrophy and thereby become somewhat available for other uses as well.

Here is an article written by a self-experimenter.
December 15, 2000
Answer: What a perfect question! You actually have talked to just the right person. I have a business associate that worked for the company that produces this in Australia. Several years ago, I ordered 10mg of Long R3 IGF-1 and used it for several months. What I found out was truly amazing.

Before I tell you about my results, let me tell you that if you are going to use IGF-1 then make sure it is the Long R3 version! Let me explain. Regular IGF-1 like what is produced in your body is transported around connected to binding proteins. There are quite a few of these and their main purpose is to grab ahold of the IGF-1 peptide and keep it from being quickly degraded. Without these binding proteins, all of the IGF-1 would be metabolized in the body within a few minutes. The problem (at least it seems like a problem but might actually be a good thing) is that these binding proteins basically prevent the IGF-1 from performing its function. As long as IGF-1 is attached to the binding protein it cannot do the cool stuff that it wants to do. Regular IGF-1 must be released from its binding protein in order to accomplish its mission. Part of the problem is that much of the IGF-1 is degraded before it is released (seems like much is wasted doesn’t it?)
With Long R3 IGF-1 this problem doesn’t exist. Understand that the Long R3 version does not bind to the various binding proteins. It is free to move throughout your body and immediately start doing all the cool stuff that it wants to do. Again, understand that the Long R3 version is several orders of magnitude stronger than regular IGF-1.
If you would happen to use regular IGF-1, you would need several milligrams per day in order to get the desired effect. With the Long R3 version, you need only microgram quantities. Long R3 is also inherently MUCH cheaper to produce. What I am saying is that for the average person, regular IGF-1 is not practical-it is too expensive and you need to use too much. With Long R3 IGF-1, the price to results ratio is pretty good!

Something else I want to explain is how I went about preparing it for injection into my body. Unfortunately, this is not easy and the average person will have a hard time doing it. At the time, I worked in a sophisticated lab which had all of the necessary equipment. I ordered 10mg of Long R3 IGF-1 and it came in a single flip-top vial. 10mg might not seem like much but believe me, when it comes to Long R3 IGF-1, it is a ton! Some people might say to just add saline to the vial, keep it in the fridge and inject it when necessary. However, this will not work well because the IGF-1 is not highly stable and will degrade in an aqueous environment. 10mg was enough for many months and I needed a way that would allow the IGF-1 to remain potent during this entire time. I did my research and developed my method. I ordered what is known as microvials and sterilized them. I then diluted the IGF-1 with sterile water and added just a tad of acid to increase stability. Although it took quite a while, I then used a micropipette and alliquotted an amount of solution that contained 50mcg into one of my microvials. I closed the microvial and then froze it in a deep freezer. When I was ready to inject, I took out one or more of my microvials, thawed it out, combined it with saline and injected it.
When I first started taking Long R3 IGF-1, I used 50mcg every other day. Amazingly, within days, I started noticing some effects in my body. I felt super hungry all of the time and just felt “anabolic”. I can’t describe this feeling except to say that it was very similar to being on anabolic steroids (I wasn’t on at the time). Within one month, I gained almost 17 pounds of fairly lean mass! After the first month, something happened though and I noticed that it didn’t seem to be working that well. I upped the dosage several times over the next month to keep up the desired effects. On the third month, I was using several hundred micrograms per day but wasn’t noticing any further gains. All in all, I gained about 20 pounds of pretty solid mass!
Please notice that almost all of my gains were within the first month of taking the Long R3 IGF-1. After this first month, my gains slowed down considerably and eventually stopped altogether even though I was taking high dosages. Why did this happen?

From all of my research.......I suppose one of two things might have happened to prevent me from making further gains. What I truly suspect is that the Long R3 IGF-1 downregulated the amount of binding proteins being produced by my body (research confirms this). When I first started to inject the IGF-1, I was supplementing my own body’s IGF-1. I not only had my own IGF-1 working throughout the day but I had the potent surges of Long R3 IGF-1 that I would inject. Over time though, the binding proteins were downregulated. Of course my body continued to produce some (albeit less) IGF-1, however, because there were very little or no binding proteins it was quickly degraded. From what I can tell, I was in a state where 95% of the day my body did not have the benefits of IGF-1. Basically, it got what it got when I injected the Long R3 version.
The other possibility is that I built up antibodies to the Long R3 IGF-1 which basically sought out and destroyed what I injected. Although possible, I don’t believe this actually happened because it is not supported by research. I have seen no evidence which suggests that Long R3 IGF-1 causes antibody production.
To fix the above problem, one would have to cycle the Long R3 IGF-1. The best thing would probably be to take it every other month. This would allow your own body’s IGF-1 and binding proteins to return to normal.

Overall....I had a good experience with Long R3 IGF-1. The results were different than with steroids. I have noticed that steroids cause preferential growth of certain muscles, especially those that are stressed (as in lifting). The IGF-1 though seemed to cause my entire body to get a little thicker. I guess IGF-1 is less compensatory in nature and exerts a more whole-body anabolicity.
Would I recommend IGF-1? To the right person who is very careful and knows what he’s doing and has a good background in the sciences and has access to a good lab, YES! However, you can tell that I have listed many prerequisites to using it. For the average Joe, I believe is is just too complicated to be safe.

I do IM injects but to prepare it here's an easy way.
It comes in 1000mcg per ml.
Take 2 ml of of bacteriostatic water water an add it to the vial it came with. Now you have 1000mcg per 3 ml.
Take 2 slin pins and fill them from the vial. Each pin holds 1ml. Freeze these pins. Each pin will have 333mcg in them and there will be 333mcg left in vial.
Add 2 more ml of of bacteriostatic water to what's remaining in the vial. This gives you 333mcg in 3 ml or approx 100mcg per ml. Now you can use a slin pin to measure out the amount. 30mcg would be 30 on a slin pin, 40 would be 40 and so on.
When you run out, take one of the frozen pins and add it to an empty vial. Add 2 ml of of bacteriostatic water and you have the same solution as before (333mcg in 3 ml or approx 100mcg per ml).
I do mine 5on/2off at 30mcg for 4 weeks. So I end going through 2/3 of a 1000mcg a cycle. So for every 2000mg purchased I get 3 cycles worth.

Would it be smart to take IGF1 in conjunction with GH?

or is this more so a waste of money?

This is what wyldone said in the IGF-1 IGTROPIN post on the main board..
"to answer your questions!

the R3 IGF-1 does infact work and this is how you should run it! First and foremost you must be in an anabolic state, with this I mean anabolic/androgenic ratios! second you are wasting your time and money if you use this without GH. and last but not least the proper dosage is between 20-40 mcg post-workout(within 1 hour of training) If you guys have anymore specific questions post them and I will address them. You can expect to pay around $300.00 for 1mg on average from GenSci. wyldeone."

igf-1 and insulin

question for you more experienced users....while taking igf-1, it is like insulin, which can cause hypoglycemia. do you counter act this effect the same as with normal low blood...by taking simple sugars immediatley? the reason i ask is that i am diabetic, so i already manipulate my insulin to try and help me grow. any suggestions on how i may run it with the insulin safely? thanks for you help!
