I personally used it. I actually used it more than once. The first time i experimented with it i used the normal 6oxo which was highly recommended to use with any prohormone. The second time I purchased it i used nolvadex as a PCT and the results were phenomenal. Yet like allot of people have replied it is highly toxic to your body which you know it will then have negative side effects. But thats beside the point because I'm still alive and walking. But if your gonna toxify your body then i would recommend dbol. Though some say they have lost some strength with dbol i didn't lose much with m1t in fact i gained 20 pounds. It's your choice i hope my advice helps.
