Well my supplier sent me generic 191aa HGH instead of the Somatropin/Jintropin 192 rDNA yellow tops I normally get.

They dont have it anymore, really irritating. I've heard theres issues sometimes wit reactions on 191 stuff. I've never used it.

I also heard its a lot weaker.

Any suggestions? I'm quite irritated... thinking I might start using Sermorelin instead.
