The not the whole story though. The androgenic component is more of a factor in prostate hyperthrophy than first thought and the anabolic part will grow muscle. . For example, Proviron is pure dihydrotestosterone, thus pure androgen and it'll make you hard as a rock but won't grow much muscle. But your prostate will swell up like a watermelon. Primobolin was thought to be murder on the prostate but it's not really that bad. (Could be that it was thought to be DHT beased but it's DHB based -- but that's another story). The anabolic component has less side effects and , in my opinion, should be emphasizied in a stack though it's the androgenic which causes more of a strength increase. This is why I think you only need two compounds per cycle.
