Research purposes only, notwithstanding for human consumption, do not inject. Apply to muscles where desird.
As with all peptides and synthol, it's a research supplement not intended to be injected.........now if you had let's say a rat and he had a mini gym and you wanted to see how well peptides and IGF work, one might inject into the muscle group your rat will be working out and see how well the product works........of course if you had a rat, and a gym to do this experiment in the name of research only. My rat loves IGF and has made great if joy awesome gains compared to other rats in his gym and other rat buddies.......just sayin.
