A good friend of mine had 2 of their products assayed, and they were both under-dosed...but not horribly bad. The sustenon was about 229 mgs.per ml, and the deca was about 180, instead of 200. One bad thing though, he ordered some masteron, and it assayed out to be trenbolone, kinda wierd since he didn't mention the color. I too have heard of sterility issues concerning these products....
