I got a 20ml bottle of this crap and am down to the last injection thank god. This stuff hurts like no tomorrow. I was rotating injection sites and the pain would be worse no matter where I'd put it. I've had good luck with TT test and Deca but this stuff is for the birds. I couldn't walk after the first time I stuck in my ass. I noticed that the bottle would never suspend and talked to my source he said that was odd and has never had any complaints until now. He thinks I got a bad batch but also thought that this bottle could be extra potent so I stuck with it. I had pretty good results but not worth all the hassle of pins cloging and massive welts it left for days. I had to sitck myself 3 time for one injection because my 21 gauge pins kept getting cloged. Just my 2 cents flame away.
