Whats the best glucosamine hci, chondroitin sulfate and msm product out there for athletes?

See below. In my opinion (and not necessarily based on any head-to-head studies), i feel that osteo bi-flex and cosamin ds are two of the highest quality glucosamine and chondrotin products. There are very few studies that demonstrate a benefit from msm, so i personally do not endorse its use.
Who knows? Dietary supplements are not regulated by the fda, so there's no answer to your question. Everyone well tell you theirs is best, but.......
