Progain also contains MCTs, a unique form of fat which is less likely to be stored as body fat than long chain triglycerides. Progain includes Nutriose and Inulin, two unique low glycemic carbohydrates that don't raise blood sugar and insulin levels, like sugar laden weight gainers do. Progain then includes the anabolic environment support formula, 'Nitrogain' a blend of NAC, Taurine, chromium and glutamine peptides.
