most of the peptides like IGF and MGF would work absolutely wonderful, if only you could afford the 50,000 dollars or so it would cost per milligram for legit stable product.
This is probably true... supposedly there are places where you can buy peptides like IGF in bulk, and steps to take to mix it into something usable, but I highly doubt that works in practice.
I also doubt there has been anyone in bodybuilding circles that have had access to real IGF, for any real period of time, despite how long it has been around.
