I used it myself. How can I put it? The effect should be there, but it's really spicy. I can't say yes, I wrapped it in plastic wrap, and then I took a bath with exercise at last. Never take a bath with hot water, it will hurt people. At that time, it had some effect, but I think it was mainly effective for fat meat, and the muscles didn't feel anything. My thighs have become thinner and my calves have not changed. If you really can stand it, you can try.
