this is so hit and miss... i have heard good things about peptide bridge in the past but i have no personal experience with them... i used great white a lot in the past but they have definitely gone downhill... im not sure i would trust them at all on quality.. try peptide bridge
I used it to improve tendonitis in my traps and to improve my shoulder joint comfort. I felt a drastic improvement after the first 2mg shot. But that is only my experience. Yours may be different.
