What makes you think AAS work mostly on the arms and shoulders? Look at any BBer and say that again, lol.
I can’t answer your second question, because it revolves around an incorrect premise - the arms and shoulders thing.
Would there be any side-effects from IGF1? Well I don’t mean to be blunt, but just how much info did you read?
Ok. I’ve done 4 cycles of deca/test and have noticed the largest gain in the shoulders, the only bodypart that got so large that it got a little tight even though I dont do direct shoulder work. I’ve noticed significant gains elsewhere but as for me, the shoulders were the biggest gainers, as they were one of the underdeveloped bodypats on me, but are now oversized proportionately, again without direct should work. Dont the arms and shoulders have more anabolic receptors?
W/ the HGH i’ve read about teh acromegaly, the increasing size of organs, joint pain, but i’ve done searches on IGF and most of the mentionings that i’ve found are from obscure medical journals which won’t help a nonscientic person out lol.
So back to the original questions
-will hgh or IGF be more effective in terms of size?
-will IGF have any sides that you should watch out for?
