What You Should Know
Bodybuilders work two phases of the sport to achieve the ultimate body – bulking and cutting. Bulking involves gaining weight and muscle while retaining lots of water. Cutting is the slimming phase when athletes reduce water retention and cut fat. GNC Refine is a cutting supplement designed to promote fat loss and sculpt the body into a rock-hard exhibit of pure muscle definition, but it is not a miracle supplement. Bodybuilders have to stop taking creatine and cut carbohydrates out of the diet during the cutting phase. If they take this supplement without taking those steps, it will not work as well as claimed.

During the cutting phase, the most important ingredients in a supplement are fat burners. These ingredients need to be proven and effective in the human body. Refine uses caffeine, yerba mate, yohimbine and black tea leaf as stimulants. We love the use of caffeine and black tea, but the average dieter may not love the effect of strong stimulants as much as the bodybuilder. Black tea contains the highest concentration of caffeine. GNC does not reveal how much caffeine is in each serving and that is a huge letdown. Refine is a great bodybuilding supplement, but the bodybuilder needs to know how much caffeine they are taking in this supplement so they can adjust caffeine intake from other sources. Overdosing on caffeine can lead to heart palpitations and increased blood pressure.
- Contains caffeine from several sources.

Refine is one of the supplements in the new Beyond Raw line from GNC. The supplement line is designed for bodybuilders who want to increase lean muscle mass and cut fat from the body before competition. We like the line, but we are not fond of the fact that GNC does not list how much caffeine is in this fat burner.
