This question is directed more towards GP, TP, and DG. I was asked this by someone and really did not know the answer. Why are prohormone cycles so much shorter than with AAS. I have never really thought about this. I have done 2 AAS cycles which lasted 8 and 10 weeks. I had no problems coming off. My longest ph cycle to date is just over six weeks. Would the benefits from prohormones stall after about the six week point or what? My thought is maybe the side-to-benefit ratio may become a factor. I find it hard to belive that prohormones are more suppressive than AAS.
