I don't know what you're after but I take "Glucosamine + 'Chondroitin Sulfate A'". I get them online at [url=http://www.optimumnutritoin.com.:0ab53]www.optimumnutritoin.com.[/url:0ab53] A 4 month supply was about 40 bucks.
I don't have bad knees but they and my hips talk to me after a hard day of wadding so I'm just being prepared!!
