Got this because it works with a Keto diet, it's made in the USA, third party tested and I only have to take 2 a day. Everything I was looking for in a diet pill. So when I first got this I was very hopeful that they would work. Began taking them right away and had more energy. Only been taking for right at 4 weeks and I've lost four pounds. It will take about a month to be sure about these, but for right now, I like the product.
