So I recently made some BAC; put .1 cc in 10 ml of sterile water then shook it up for 10 second or so and drew water out and reconstituted in my igf lr3 from peptidetech(member on here was raving about it). Shot 25-30 mcg last night to see how it was and felt some pip and joint uncomfortness mainly in my shoulder where I have strain near rotator cuff area. Then today about 2 hours before the gym(I literally took it because of the amount of carbs I ate that time) wanted to see how my body would react so I shot 50mcg in my delt. As soon as I shot it in my shoulder; I had some slight pip for hours, but when I went to the gym the pump wasn't really their. Like I didn't see anything out of the extradinoary and taking a preworkout would of gave better pumps than what I had at the gym. Was wondering if this source was legit; or if it took about a week or so to take effect?
A lot of people have some misconceptions about IGF-1 LR3 that just aren't true.
First of all, IGF-1 LR3 isn't a "pump" agent. Yes, it can potentially increase the "pump" via increased muscle fullness (e.g. increased glycogen storage) and improved blood flow, but if you're using LR3 simply for a pump, you would be better off using insulin than LR3...or even a high dose citrulline and/or other properly dosed pump products.
Furthermore, LR3's ability to increase circulation is dose-dependent...and its ability to increase fullness (glycogen storage) is both dose and duration-dependent. One's pre-use glycogen levels will also play a deciding factor...because if someone;s glycogen levels are already maxed out through normal dietary means, adding some LR3 isn't going to make a huge difference. All of these things will determine how much of a "pump" LR3 provides.
In short, the higher the dose is, the more of an acute effect you will notice, and the longer you continue using that dose, the more of an effect you will notice (to a degree), but once again, it is still relative depending on the factors above.
There are numerous variables that determine how great of a pump one might get, in general, such as: one's current glycogen levels, one's degree of hydration, type and dosage of PED's used, type and dosage of supplements used, insulin sensitivity, etc. When this question is framed with the context of LR3 use, you then have to consider other things, such as one's bodyweight relative to the dose used.
Depending on the circumstances, I could easily use LR3 and not notice any difference in appearance after a single dose, especially when used in the 25-50 mcg range. Insulin provides a significantly more potent effect on glycogen levels and blood flow than LR3 does, and it is easily possible for a bodybuilder to use a single dose of insulin and not notice any visual effects, especially when using smaller doses.
The point here is that people shouldn't be drawing conclusions regarding a particular product's viability based on the level of "pump" they experience, especially after using it for only a day or two.
A much better way to determine it's legitimacy is to look at how it effects your overall appearance by cycle's end (IGF LR3 tends to provide a fuller, tighter and leaner look after a while). BG levels may be a useful determinant, but that will depend on one's insulin sensitivity. Insulin sensitivity can make a giant difference in how much this compound affects BG levels, so some people will be much more/much less responsive than others in this regard.
