I'm curious.... what sort of doctor do you see for your HRT? Do you by any chance see one of those life extension clinics?
I have had joint issues for years.. I've tried alot of stuff and wasted tons of money... I have impinged shoulders, a bad c-spine, and a couple of bum knees... for me, the best thing was incorporating a good daily stretch program, seeing a good chiropractor for "maintenance"... as for supplements, I take on a long-term basis a high potency glucosamine/chondroitin/MSM product and cissus q. powder... are they miracle-workers? No, do they help? Sure. And you have to take them daily for months and months for them to have their moderate effects...point is, they're not harsh on your system like deca.
