I also took 'M' and Tribex together.. actually, the tribex seemed to kill my sex drive. The 'm' if anything, helped it. I think you can find vitex a lot cheaper than spending 30bucks on M.
Vitex increases LH in men and women. I am not sure if or how it gets rid of prolactin gyno.
I'm just going to buy that post cycle stuff from protein factroy (when ever it comes out, ??)
