DURING TRAINING
To support glucose levels and sustain muscular output, drink ½ serving every 30 minutes. Endurance athletes competing in prolonged excerise should sip 1 serving in 8-10oz. water for more energy and hydration.

For workouts lasting up to 90 minutes, consume ½-1 serving within 40 minutes post-training. Follow this with at least 20g of high-quality protein, such as 1 serving of GAT Sport Whey Protein. For workouts lasting longer than 90 minutes, consume 1 serving of CARBOTEIN® post-training and another 1 serving 60 minutes later.
