No offense Smooth, but I see plenty of these posts that don't add up or you don't have the full story.
1. What kind of Athlete? If I was training just to be athletic, I wouldn't take more than 250mg test per week
2. Your interpertation of a solid diet and mine, could be 2 different things.
3. Injury prevention? I don't see why taking AAS is going to help that. That goes with a sensible training program and proper rest.
4. How long have you been training, what kind of program?
5. Without seeing pictures, how can we advise you fully?
6. Not everything is a cookie cutter situation.
7. How many cycles have you done?
8. Have you done proper bloodwork?
9. Years of training?
10. How old are you?
That is my top 10 list for why it is hard to answer your question.
