I trust my supplier and he has used this himself, I didnt ask so much about the effect since this was the "real deal" and hes always in shape. I just got a bit confused since I got two different vials.. I had almost the same deca in 2012(The small vial) and used it with Omna and I got results, my frend also took this deca and he was very satisfied. But if its a knockoff its better to just return it, where I live its illigal to use steroids so its difficult to get it tested.. And I wont inject cortisone in my ass cheek...
Thanks for answers!
