 I have. Yes, I have. Well, that's wonderful, Frederick. Well, I have to also say this is synergistic in the fact that it's hard to exercise if your knees hurt. But using Collagenate, I got the greater improvement of my knee, and I also got the weight loss benefit by including exercise in the program. Definitely, because it sounds like your knees started feeling better within a week, within six to seven days, and then you lost the inches in your waist over the next couple months. That's right.
