I personally did not feel any different using it. It kind of tastes like peanut oil and I do wonder what is actually in the bottle. I haven't noticed any difference while using it - joint pain, etc. I would not recommend purchasing the product. I believe it is a waste of money. I'm not sure what is actually supposed to do for you, but I think it is a fake/scam. I also have a 1-800-764-3914 number to reach someone at this company. I would like to read some reviews from other customers/users of the product.
Bottom Line: No, I would not recommend this to a friend
