BRO...let me tell you...I took that shit for a long ass time. It was the test I used for my 1st two cycles....unless you like pain, stay clear from that shit. Doesnt matter where you shoot it, it will knot up and leave your ass in so much pain, believe me. I have horror stories. Its also pretty dirty. It comes from mexico, I was down there all day today buying clen and fuckin around, and I poked my head in a few places that had test 400 but you have to be VERY careful and know exactly what you are looking for. About 80% of the places that sell it down there, its fake stuff. I know exactly what to look for and I have been ripped off before. But Id honestly stay clear of that dirty painful shit.
