Gluta-Tren enhances workout performance replenishing glycogen and elevating glutamine plasma concentrations. Taking GLUTA-TREN during and after a workout or any physical activity helps reduce oxidative stress to muscle tissue as well as buffer lactic acid. GLUTA-TREN's Rapid Recovery System has many benefits, like lowering Creatine Kinase and increasing ATP levels. The best way to take GLUTA-TREN is to take a single serving dose of 16.5 grams mixed with 10-16 ounces of water as a pre and intra workout drink sipping it 15 minutes prior to physical activity and finished into your activity.
