I bought a bottle of the stuff a while back for dirt cheap. I didnt notice a damn thing except maybe anti-catabolic properties, but I wasnt using anywhere near as much as you. I used 1cc/ED IM for 4 weeks while cutting, it helped a little but not worth the injection site pain. I tried using SC site injections in lovehandle area a few weeks ago, 1cc ED while on usnic acid. I really don't think it did anything. It burns like a mofo subcutaneously, I actually still have a little soreness 2-3 weeks later.
I guess it could be effective at 6cc/day, but I dont think I'll use it again.
