First of all get to minus 15% BF only with nutrition and training. Some serious training should get you easily in the 13% zone.
Then, depending of your goal (lean muscular or lean beach body) bring the tren acetate (together with low test prop) or clenbuterol in.
This will get 99% of the gym rats where they want to be.
If you want to go to competition level, that's another story.
Masteron and winstrol are for the advanced, and anavar and primo are weak (although a decent choice for those who want to keep it "safe" and feel well).
