John, I give Cosequin - that's the brand name, and considered to be very consistent with their formula. I purchase mine from ebay. I keep searching till I find a good price and bid or some are marked "buy it now". I got 3, 100 count bottles for $55.00. That's darn good for 300 chewable tabs. My vet charges almost $90 for a 60 count bottle. When I told her what I paid for the same product on ebay, I honestly think she thought I was lying.
