Ok, first of all I know a lot of people don't seem to like IGF-1 and seem to think it's all hype, but besides that, I've heard you want to inject it in the muscle group you just worked immediately after workout, with hopes that it'll create hyperplasia (controversial, I know).
Injecting into biceps and delts is no problem. Where would you inject on leg day? Is it safe to inject into calves? I know most people are against steroid injections into calves and say they are extremely painful.
Are there any other spots good for injecting IGF-1 Lr3 or would you just stick to biceps and delts? It's only a slin pin.
