site injection for igf-1

does igf-1 have an effect on the body part that it is injected in ,i read alot about injecting into the biceps was wondering why.

some said that it helps with site injection...but really it does help with overall laggin parts...so if you u site inject you will still get overall effect regardless

i truly believ it regenerates cells in muscle, and nerves in that area as well as i had a leg muscle go flacid and it wasnt suppose to come back from the nerve damage and igf cured it, or maybe the dr's were full of shit and it would have came back anyhow but none the less im a believer what can i say
