I read a study someplace that compared subjects that took it 5/2 and 7 days a week. The study showed that both got near identical results. Also, check out Gavin's research..
From Gavin....
I am happy to help you out bro as it is critical to get the timing sequence down for optimal growth. I have been personally testing different protocols with igf use, having done over 20 different cycles and timing schedules. I also have a few competitive bodybuilders and test subjects off-season testing my new protocols. I have nailed down what I feel is the best protocol at this time, though everything is subject to change as I keep researching.
For now I have found that less is more. I highly recommend using a minimal schedule for all short chain sequence peptides, which include igf, insulin and even gh. I recommend using no more than 3 days per week, 2 days is fine, but no more than 3. The reason for this is that we are trying to prevent cell over-saturation and closure. All three products should be used in a similar manner.
The protocol is as follows; inject all products post workout, preferably after training large muscle groups which cause the most glycogen depletion, hence providing faster uptake of peptides. A sample layout is to inject Monday, Wednesday, and Friday.
Immediately post-workout inject 10-15iu of growth hormone IM, using a insulin pin and inject in any small muscle group such as delts, triceps, or biceps. Wait 20 minutes for the half-life clearance and conversion to igf to begin its sequence from the growth hormone and then inject a small dose of igf to create a synergistic super charge of the conversion process. I would recommend no more than 30mcg at this time. 10 minutes later you will take Humalog insulin only, and inject 5iu. I recommend starting with 5iu because Humalog has a very rapid onset and is easy to control with sugar. In conjunction with igf, you will be hyper-sensitive to insulin so start small and slowly work your way up to a maximum dose of 12iu post-workout. You will want to have around 80-100 grams of simple sugars such as dextrose and grape juice and an additional 60 grams of whey protein at the same time as your insulin. You will then eat another moderate glycemic index meal one hour after your high glycemic shake.
The reason for the high dose growth hormone is to take what would normally be your one week intake of gh and spread it out into 3 equal doses, injected pwo. This will create a truly anabolic rich environment and you will also benefit from full uptake due to your pwo depleted state.
So there is our post-workout regime, 3 days per week. Certainly you should take more than this, shouldn’t you? For most lifters, this protocol will be sufficient for growth. For someone with at least 6 months of gh use, 5 or more cycles of insulin and who no longer responds to typical igf protocols, the following regime may be followed: In addition to the above outline post-workout method, you may add additional doses of igf as well as insulin on the same day as your post-workout injection.
I would highly recommend you take 15mcg igf an additional two times per day. By taking less igf more often you will prevent cell over-saturation as well as receptor down-regulation. Creating a cell rich environment that saturates the cells infrequently will target massive cell proliferation. In addition you will take insulin 20 minutes after the igf on those 2 additional injections creating an anabolic rich environment that will last all day, 3 days per week.
For a sample protocol for someone that works out after work, I would recommend you do the following: Take 15mcg upon rising in the morning, followed by 10iu Humulin R or Humalog 20 minutes later. Immediately eat a carbohydrate rich meal with quality protein and low fat such as bananas, oatmeal and egg whites.
For lunch, take another 15mcg igf with 10iu insulin and have another moderate glycemic carbohydrate meal and protein with minimal fats. Follow the above listed pwo protocol to complete your three time injection schedule which will be used three times per week.
If you follow the outline laid out for you above to the letter, you will put on a massive amount of lean mass with a minimal amount of fat. You will need an anabolic and androgen rich environment to complete the schedule such as testosterone and tren in addition to the peptide products. T3 and T4 will not be necessary on this schedule as your thyroid levels will not be affected.
