Have you already started your cycle? What are your complete stats bro? Age,weight,bf, years lifting and cycle experience? What are your goals? Hopefully you haven't started without having pct in hand. Are you using aromasin?
Would like to hear some stats man. Rick got you covered with the pct but to help you the best we can, let's hear your age, height, weight, bf%. Planned cycle layout and goals for the cycle would be great too.
