I was going to mention the pentosan too. I dont think its use is widespread in humans, though.
Glucosamine never did much to me, plus you must load up 30d.
Deca is best to me, 200-300mg wk. Even test seems to work to some degree.
Probably winny and EQ is the most agravating.
Then you have all the NSAIDs, most of which will cause digestive tract problems (toxicity/ulcers).
