I'm new to this board and I got a question.. since GH is precursor of IGF-1 wich is responsible for all gains in muscle mass why so many people advocate using GH for longer periods of time at 2-4 IU ed and when it comes to IGF-1 LR3 they say use it for four/five weeks. Would it be more productive to run GH at 10 IU ed for a short cycle like few weeks? Assuming you can take the sides. I know it's not cost effective and IGF-1 would be a better choice but still... does anyone have any experience with short GH cycle with higher amount?
