JetMassGAT Sports JetMASS is a volumizing creatine system built around a pure, patented Creapure creatine monohydrate dose (5 g per serving). By combining creatine with 13 g of fast acting carbohydrates, JetMASS triggers an insulin response that drives nutrientsincluding creatineinto muscle cells for maximal uptake. This approach optimizes the phosphocreatine energy system, which fuels short, intense efforts and helps increase strength, power output, and
