Well i am 18 and currently weight 170 and i am 5'9 and am getting ready to take another Deca cycle. I was happy with the first one i got but i think that because i didnt have a good diet i didnt get as much as i should have. How important is diet with a deca cycle. Also i was taking in about 200 grams of protein and worked out great. I was just needing some tips with taking deca and how to get my max potential out of it. I take proper pct and everything is fine no deca dick or anthing else.
