I got some info from a guy at my gym about deca, he told me that it will help put gains specifically where you work out. For example I dont want to get bigger up top, but i do want to put more mass below, so would working out heavy on legs and light up top help promote more mass in my legs than in my upper body. Thats what I want because i am happy with my size up above. Or should I stick to winstol and lean up?
