I am a college pitcher with testing thats not an issue. I am a 6'2" 186lbs right handed pitcher with my fastball from 86-90. I have little to any body fat and gaining weight is a major issue for me. I took a 10 week cycle of synthetic testosterone last fall and that was the hardest I have ever thrown at 93. Ever since then i cannot get close to that velo. I was not informed to take any anti-estrogen or anything after my cycle. Is there something that I should take to make sure that everything in my body is functioning healthy? I.E. for genital region as my testis are still at a smaller size. I also want to know what would be good for me to take to increase both strength and size in my legs. I seemed to put all my strength and weight in my upper body. I also go through extraneous workouts to the extent of puking. What would be something good for me to take to increase velo and size in my legs while being able to dominate our team workouts and remain healthy for a pitcher??
