"Supartz
I hope I spelled it right. That is the "joint lubricant" , it is derived from a rooster cox comb."

I have a coworker friend who is using this stuff. Old football and wrestling injury, and he's overweight, but its working for him. He's ~52, and he's wanting to buy some time before he does the knee replacement, knowing that knee replacements only last so long before you have to do it again, and he only wants to do it once. After getting periodic injections of the stuff, he went from limping and lots of pain, to no pain, and he's walking every day to take off weight.
