Hi yah,
I am in a similar boat. I was a 'clean' professional athlete who is now making a comeback in a different sport which requires a large amount of power (at the age of 40) However, my profession is in performance sport. I was a track coach (now an academic). I have knowledge of the negatives of steroids but am now looking into its uses. Most of the information that I have found out there is related to hypertrophy and body building.
What I can say about your situation is that you can look into the following areas to find natural solutions:
1/ Micro stretching: Developed by Nikos Apostolopoulos

-I have conducted research using this technique and have found it very useful for both development of power as well as dealing with micro tears.
2/ German body building methods: Probably best exemplified by Poliquin's "Manly weight loss" book. Basically eccentric weight training may be able to overcome the shock of the jump training / plyometrics that are common in track.
With regards to the possibility of steroid use, I am just now starting to get relatively useful information. I will keep the info in layman terms. Bulking steroids -even in relatively low amounts- are not good due to the water retention. Cutting steroids are a possibility. Anavar seems to best fit this description.
However, as I mentioned I am having problems find legitimate information. I am off to Eastern Europe and German next year to search out qualified knowledge.
If you find anything out there on sport performance and sport injury regarding steriods please let me know.
Good luck
