I've been tring to post this a couple times but when i hit save it doesn't show. Anyway i got some gear from a local shithead that I think was bunk I hope this is O.K. to post if not, my apologies. My first bottle was jzpharm or jinan that said for experimental use only and I think it was bunk, not to mention hurt like a bitch! the other was medix parmaceutical human grade. Any input?
