I took this product for a month and I saw great results. I am on a sprinters workout schedule and I found myself unable to drop an extra 15 or so lbs to get down to proper racing weight after being injured. I lost 20 lbs in one month combining this with assault preworkout and I was in better shape than ever. I never actually got up to the full dosage, usually I would take 2 twice a day and that would be more than enough.
