My advice would be DONT start AAS at 20% body fat. At 285 lbs you are probably closer to 30% even at 6'3. You will have a very hard time controlling estrogen and you will not see the results you think. As for winstrol....you won't see a thing from it unless you are below 10% body fat in my experience. It is used a hardening drug and will NOT make you lose fat nor will any AAS. My advice, hire a nutrition coach and when you are at 15% or below then start AAS. Test, eq, anavar. Mild compounds. Get a few cycles under your belt and then try some tren and other compounds. DIet is absolutely the most important aspect of bodybuilding or just attaining a desired physique. All the drugs in the world won't outwork a shitty diet
