Why do you want to do that? You should let your body rest and return to homeostatis. If you plan on running long cycles or never coming off - be sure you have good medical coverage, an understanding care provider and routine bloodwork. If you wanted to live a life of with superhuman androgen levels - deffinitly don't do it blind folded... have routine medical check ups to be sure you aren't developing any serious health problems.

I wouldn't count on making a full recovery after 30 years on by simply jumping on some Clomid and such... it would probably take some serious medical counseling by someone spcializing in endocrinology...

I know being "on" has its kicks - especially testosterone... but there comes a point where you need to come off high androgen levels (and yes - even 500mg/wk of testosterone is considered high; it is many times greater than endogenous levels) and let your body regroup...
