Hot-Rox Extreme is a thermogenic supplement in pill form that is meant to increase fat loss and calorie expenditure, increase mental focus and physical motivation, and suppress appetite. I find that the product stayed pretty true to its description, as I would take one in the morning and be pumped for the gym. I believe it also helped me make more progress in the gym because I pushed myself harder and achieved more goals. I took it for one cycle and dropped a significant amount of fat while maintaining a large number of cheat meals.
While I did have more energy while taking this, it also made me a little too wired at times. You can take 1-2 capsules twice a day, and if you are at the higher end of the spectrum you are susceptible to jitters, occasional palpitations and/or difficulty sleeping (if you take it too late at night). I also had trouble eating sometimes, normally within 1-2 hours of taking the supplement because it does suppress your appetite. Directions recommend eating 20-40 minutes after consumption, but I found that it was a major task to get a meal down after just one pill.
