Creatine Pure capsules from Fire Nutrition® use a raw material that guarantees the quality and safety of the product. Creatine helps increase endogenous phosphocreatine levels at the muscle level and this helps better physical performance. When a rapid increase in creatine levels is desired (as in the case of bodybuilding athletes), supplementation in loading form may be appropriate. Instructions for use: Take 3 capsules a day with a glass of water.
