Your doctors not taking into account the fact that you want any muscle on your frame. While were on doctors, i doubt he would recomend you take steroids either.
All im saying is that you can see my stats and im just barely 20% moving my way down to 10-15% after this winters bulk. I couldnt imagine weighing less than 200 again, that was like 7th/8th grade for me.
How long have you been working out? It seems like you might have better results just hitting the gym. Theres no real "cutting" cycle, in my opinion, theres just some AAS that give you lean gains, while others are more likely to bloat you up.
