there was a post not all that long ago from a guy saying several of his ampoules he got were broken but z was gonna make that right by sending more, but the guy also mentioned that many of them didn't have a full ml of gear and they weren't all filled exactly the same.
i find it hard to believe that anyone would set up business for a product going to the end user that had not been at least sampled by the seller.
i you look around though, it isn't hard to find wholesalers, even ones that will dropship, selling "human grade" steroids along with an assortment of other counterfeit items.
and that is just looking online.
if the stuff looks pretty good and has afairly accurately dosed real steroid in there that their lab made, it will probably sell and most people will never even realize it.
still, hard to believe a source wouldn't know that is just bad business. never stand as a middle man between your own customers and a person or product you don't have a handle on, or, as seen here and on other boards, your reputation will suffer for it.
