Roctane takes athletes' top choice for an energy gel, GU, amplifies the original recipe and then adds new ingredients to boost performance in sustained, high-intensity efforts. Here's how it's done:

We start with original GU's superior mix of complex and simple carbohydrates that provide quick and sustained energy, electrolytes for replenishment and caffeine to tap more power and diminish pain.

From there we increase the amount of histidine, an essential amino acid, to act as a buffer and slow the energy-sapping lactic acid build-up in muscles.

We mix in higher levels of citrates (potassium citrate, sodium citrate, and citric acid) to help speed the conversion of carbohydrates into energy molecules and, like histidine, help mitigate acid build-up.

We also add more of the branched chain amino acids (BCAAs) leucine, valine and isoleucine to serve as another fuel source, aid in recovery and help maintain mental focus and reduce fatigue by limiting the central nervous system's production of serotonin.

Finally, we add a new ingredient, the amino acid complex Ornithine Alpha-Ketoglutarate (OKG) which limits the body's tendency to break down muscle protein tissue during extremely hard training and racing days. OKG keeps you going longer and promotes a speedier recovery.
