After hearing from other friends who use this product, I recently purchased it. With the very first dose I noticed a huge difference between this and the other fat burner/appetite suppressant I had been using. This product really suppresses your appetite. As opposed to salivating in anticipation of the next meal, I have to remind myself to eat and keep my metabolism up. I am within 8 pounds of my goal weight, the hardest pounds to take off. This product is making it easier, and the pounds are coming off. Plus, the caffeine level is low - only 50 mg per caplet - so I don't feel jittery or nervous. I'm pleased that I finally found it and that it works, and it does it at 20% of the cost of the other brand I had been taking!
