Its simply a logical explanation, I put testosterone into my muscles, My body recognizes it. My balls stop doing there sperm work. I put on about 15 to 20 pounds. 2 to 3 months later, I get off, my dick doesnt' work for a week, and clomid even makes it worse. I don't see how any one makes consistent gains who are off and on steroids. I can only see how people who constantly cylce hard, then soft, and post cycle, mixing androgen with other anabolic acting substances make constant gains. The body has a balance, and eventually when you come off gear, the balance will force itself back to equilibrium. Hence losing all the size.
