i have placed so far many orders for me and my gym buddies and i can honestly say i'm 101% satisfied . a friend at my gym asked me if it was possible to have a sample of masteron propionate so on my last order i e-mailed MTS asking if that was possible . To my surprise th├ęs sent me 2 vials of masteron . Awesome stuff right there guys....no wonder half of my gym is running MTS gear . THANK YOU
