I used this product and it works. Trust me it works I've been prescribed all kinds of medications nothing worked but these capsules. I'm so glad I bought these. Only used for 7 days and I haven't had any issues. The real test was after sex and it was no smell. If you're on the fence don't be.
Output:
positive
