IM new to the forum. Im 24, I have never used gear. I have been doing research and that is what led me to this forum, and it seems as though you guys are helpful. Is their a difference between IGF-1 and IGF-3 besides the length of time it stays active (If that is even correct)? Would you need to run a PCT? Is IGF less damaging to the body? Is it even worth trying an IGF cycle (Would gains be significant)? I know im not ready yet. I have a lot more training to do prior, but I would like to continue more information before I decide to use gear (maybe Next year).
