I agree with @RampantBadger on this one. Based on what you have provided, I think a proper training protocol should serve you well.
I take the view that AAS is serious business, and should be taken only after serious consideration. To me it doesn’t seem that you have done the research work to the extent you should (I could be wrong here, I really don’t know much about you). Additionally, AAS is going to help much more for a sport like BBing or Powerlifting compared to sprinting. Don’t get me wrong it will help for sprinting. I just have a hard time justifying use for rec. sprinting on the beach.
If you want help more with lifting goals, post your stats, and maybe a faceless pic. That will help with determining where you are at development wise. Keep in mind that many sprinters are very strong. You should be able to gain a bunch of that strength natty. Once you are getting to good strength numbers, then maybe reconsider.
Look up Ben Johnson’s training. The dude was like 165, at ~5’9", and could bench 450, and squat around 700 lbs. I am not saying you need to get to those numbers, but if you are at 200, and 300, you can get much better without AAS. Again, I don’t know where you are with your lifting. If your numbers are very good, maybe AAS is for you. If not, spend some more time natty.
