i'm prone to MPB but i've been using the previously mentioned hair protocol for years with fantastic results. in fact, about 6 months ago my hair was the thickest and densest it's been for as long as i can remember. all that said, i made the mistake of running masteron in my last cycle. f-me. it's been falling out like nuts. steer clear of masteron if you are prone. i'm fairly confident i'll grow it back, but only time will tell.
