About a year ago, I purchased OxyElite Pro as a way to enhance my energy levels and decrease my appetite. I was impressed with the lack of shakiness and the appetite suppressant qualities. With exercise and a better calorie intake I was able to lose the extra pounds I had acquired and not go broke in the process. Although it is a bit more pricey than the average appetite suppressant, I noticed less side effects and only needed an average of 2 a day. For a bottle of 90 capsules, at GNC you would pay close to $50. This lasts me about 45 days and I also make sure to take a multivitamin and stick to a normal exercise routine. Worth every penny if you are serious about losing weight.
