Biceps 50mcg each. I wanna address one thing on IGF1 LR3. Some say bilaterally applications are unneeded as IGF1 is systematic and travels through the body. Studies & numerous logs show IGF1 LR3 has localised anabolic effects. In other words where you apply it will grow.
Also, the intestinal growth seen in top tier IFBB is said to be IGF1 use.... I think those w/ more experience with MC IGF1 will discredit the intestinal growth. I know guys who use GH & Insulin who don't have intestinal growth (HGH increases IGF1) So what's the cause? My true belief is HUGE amounts of anabolis, not just AAS, which is 2-10g a WEEK in some IFBB pros. But Insulin @ 15IUs 2-3 times a a day! Plus Huge GH use 25IUS from what I read. & IGF1 who knows what dose... coupled w/ enourmous caloric intake.
So, IMHO, it's excess that, well leads to excess. It is not IGF1. Just been seeing couch potatoes who took HS science & think they are Sheldon Cooper or Einstein... And run of at the mouth like they know something. Yes there is a big amount of IGF1 receptors in the intestine, but I have seen no intestinal growth & I have applied it directly to my abs. Think tho this... IFBB are WAY beyond genetic potential... Phil Heath's like 5'8 weighs 275 @ 4% bf.... Arnold was 6'1 225 @ 5% They also used GH back in the old days. Cadavor shit but GH nevertheless. EXCESS EXCESS EXCESS
