Advice for Cycles Training Muay Thai

Hello I am studying about the uses of steroids and whats what now as I am considering using it to give me an edge for my Muay Thai training. I like the bodies of light to middle weight fighters and athletes (muscular, functional, and sleek). Also the faster recovery and energy boost would be a help. So would like to ask advise from people who have experience in this area. I dont want to take lots of different things. Just something simple and effective.

I am located in Tokyo, Japan so if there are other members living around here I would love to meet up as well.
