While Gnarly Pump does include ingredients that can be helpful when taken before a workout (caffeine, arginine and citrulline), it’s primary ingredient, creatine, can really be taken at any time of the day. The key with creatine supplementation is consistency. Supplementing with creatine increases your muscular stores of phosphocreatine, which leads to an increase in the generation of ATP during the anaerobic energy production. For more information on how to supplement with creatine, please see: (article link).
