## Customer Reviews

### ⭐⭐⭐⭐⭐ It WORKS!
*by R***N on October 25, 2024*

If you take phentermine, you won't have to anymore if you use this!

### ⭐⭐⭐⭐⭐ Highly effective.
*by A***A on March 19, 2014*

This supplement was recommended to me by my cousin who has used it before. I used to take OxyElite Pro before they changed the formula and pulled the original off of the shelves. If you want an effective fat burner that gives you great amounts of energy without the jittery feelings and crashes, this is the one to get. I take one pill before I lift and in about 20 minutes I can feel it working. I've been able to power through my workouts whereas before I would do a few sets and just kind of wander. I'm a heavy set guy around 270 lbs. so I've been able to see a good difference in my stomach when I look at the mirror. I still have a huge belly but I can tell that some change is being made. The price I paid on here is more than fair! This supplement alone at GNC will run you about $50. Get this product and get it on here for less. It's not a miracle pill, but it definitely works.

### ⭐⭐⭐⭐⭐ I am so amazed by this product
*by R***S on May 10, 2018*

I am so amazed by this product. If you do not have a high tolerance for caffeine please eat something with this. The first day I did it without eating and I was going nuts. I got over it. At the gym I was pumping. This is my second day using it and I ate it with some food and lots of water. I feel better than the other day because of the food that I ate after I took the capsule. It actually does help you with weight loss with of course a diet and some exercise! I know it's only my second day using it but I already see the scale going down! You feel it a lot without eating but i reccomend some small food with it.
