So I've been trying to strengthen both my wrists and forearm muscles for almost 3 years now. I've tried many different exercises and stuck with them for months but to no avail. I've come to realize that I simply have an unbelievably small number of muscle fibers in that area (bones are even visible). Biceps and triceps are fine though, so I don't really know what the problem is. I was even going to give up until I recently came across an article about IGF-1 and how it can actually stimulate hyperplasia -- the creation of new muscle fibers. I would like to give it a shot (assuming I can find it somewhere).
Since I'm a bit new to this stuff, I was wondering if you guys could answer a few questions/clear up a few concerns:
1) Should I inject half straight into each forearm, or will anywhere work? (and what do "IM"/"sub q" mean?)
2) Are there any other supplements that should be taken with it?
3) What effects could IGF-1 have on fine motor skills and hand/finger dexterity (I play a few instruments, so this is a major concern).
4) Is there any chance that the newly split muscle could atrophy, if the training is halted?
Finally, is this website legitimate: igf1lr3.ca/igf-1-lr3-1mg-c-54 ?
