The G Series Pro is an advanced development by Gatorade that consists of nutritional support at the three different stages of physical activity: before, during & after. The series has come about through the work done at the Gatorade Sports Science Institute & the feedback of world class athletes. Whether you train every single day, competing on a regular basis, or if you exercise a couple of times a week & play in match ups every month or so, getting the most from your body & performing to your maximum still matters; the G Series Pro helps you do that. For the three stages there are three products. PRIME is for before, PERFORM is for during & RECOVER is for after; all are catered very specifically for their respective tasks. This is PERFORM. While powders are used primarily for muscle building, this is a new development to use powder, mixed with water, to produce a drink that will help maintain energy levels & performance throughout exercise. The fluid helps maintain hydration, & then it is the carbohydrates & sodium that help ensure that fuel stores are maintained as well as electrolyte balance, all of which contributes to maintaining performance for longer. Intense workouts & endurance sports require this blend of carbohydrates & electrolytes to help athletes compete. It delivers twice the sodium & three times the potassium per 12-fluid-ounce serving of regular Gatorade Thirst Quencher. Dehydration is a danger for every athlete at every level, but Endurance Formula is designed to support you every step of the way.36g of powder is suitable for 500ml of fluid approx.
