I popped it - I've used it with no ill effects (so at least it appears to be sterile). Since I'm not sure about the source (my only source option though) I've been using it in conjunction with 200mg/week of Test E that I know to be real (TRT).
The tren I got from the same guy did cause massive night sweats and real bad sleep so it appears to be real; I quit that the first trial and now just started running real low dose of tren along with 400 of EQ that I also am hoping is real haha.
