the masteron are generally light green...the same color as the viagra.
Winstrol is more effective in terms of speeding up your metabolism and getting cut. the (oral) masteron does do a good job at giving you some vascularity, pump and training aggression though, without the tightness winstrol gives. I have used injectable masteron (drostanol) and it is alot better for hardness than the oral tabs though.
I recently was experimenting and used some of the masteron tabs with some anadrol for a week. While anadrol usually really bloats me within a few days, I did not get much bloat at all, just ALOT of muscle fullness. In this regard the masteron seemed to work better than winstrol (I have used winstrol/anadrol and still gotten bloated). Granted running large doses of 2 17aas is not a good thing, maybe it is something you could do for 10 days before a show.
