I'm a former collegiate pitcher, and I don't think any steroid would be that great for a pitcher. I never juiced when I still pitched, but I did get a lot bigger from training and eating. I was only about 220 at 6'1-6'2. I definitely wouldn't advise winstrol, I would go with deca if any. Make sure you stretch the hell out of your shoulder, hold your elbow up even to your shoulder and have somebody hold your elbow and push your hand back. If you don't as you get bigger you will lose flexibility. The muscles in the shoulder that help you throw a baseball are delicate muscles that can easily get out of balance. Good luck with whatever you decide!!!
