5’7 150. What sport? Horseracing? Jockeys usually are very competitive and will try to gain every competitive edge available. I’m just joking…unless you really are a jockey! I always hear the first cycle is the best. If that’s true, then up it to a gram a week and some NPP and 100 mg of ANADROL a DAY. No, no I’m just saying what I might have done at 15 or 16. Seriously!!! Ask away, I would of waited until I was training solid and eating the right amt of food. Only you can answer that. I was an athlete too and thought everyone was on the shit as well. In my opinion, if you cycle especially if you are doing sports specific training, plan a good off period with pct. I’ve seen and made the mistake of half assing post cycle. Its not just a serm. Keep training albeit maybe not as intense if you are in season. Keep researching and make it fun.
