I'm thinking there is some validity to this product. Although, I do workout, and do a lot of butt exercises. However, I can say the volume and firmness has enhanced since using this.

I have a front loading Miele washer and have been using this product regularly. Where this product fails is where you can't it, inside the rubber hosing of your washer. The Miele has a drain trap which you can open and drain the water out. When I did this all sorts of black mold came out and it was also in the rubber hose. I ran a bleach solution through the washer on sanitize and got rid of the mold.
