Hello everybody,
I have been reading this forum for a while, usually for laughter on night call. However, I want to clear up a knowledge gap in this forum. Flex's kidney failure had nothing to do with anabolic steroid use. The poor guy actually suffered from Focal Segmental Glomerulosclerosis. This disease is actually quite common in the African American population; interestingly enough it is also common in HIV patients and IV drug users. This is a nephrotic disease that causes sclerosis of the glomerulor tuft. Interestingly enough, the latest literature is actually showing some renal protective effects of testosterone, especially of the tubular epithelium. The pathophysiology behind that is actually quite interesting, but that is another topic by itself. Going back to Flex, if he wants to compete, he proabably could without any long term effects. He should have his BUN/Cr measured religiously, and more imporatantly he should have his BP under control. At least below 135/75, to prevent end organ damage of his remaining kidney. This is going to be his biggest concern, since if he is still on immunosuppressants, epecially if he is on either tacrolimus or cyclosporin (both of which can cause BP emergencies : which is bascially a BP over 200/110). I wish Flex the best, and I hope this post clears up any misinformation. I will try to answer any questions if you guys have any. Unfortunately I am on call tonight.

and yes I am a doctor, actually a board certified GI surgeon to be exact 
Do you think drug use or diuretics could have hastened his misfortune?
I briefly checked emedicine
http://www.emedicine.com/med/topic2944.htm and it states
"Causes: FSGS is considered primary or
idiopathic when no etiology can be identified. Secondary FSGS is associated with illicit drug use, HIV and other viral infections, and many diverse factors, such as
infections, inflammations, toxins, and intrarenal hemodynamic alterations".
Maybe a person could acquire this from an infection from needle or synthol etc. Maybe something like DNP could have triggered a predispostion or actually caused this? Maybe aromatized estrogenic hormones perform the reverse function that testosterone appears to do (as you stated a possible helpful effect of testosterone). I am not convinced that drug use could not damage the kidneys in such a way or hasten a predispostion. Drugs can certainly be seen as toxins.
I would not trust your opinion unless you were a board certified nephrologist j/k.
