Micro-Fine Creatine Monohydrate HPLC is very unique in its ability to absorb rapidly helping your muscles work longer and harder without fatigue by buffering the lactic acid build up that can occur during training. Studies have shown with the increase of creatine levels, can delay fatigue and increase energy metabolism in the muscle cells, improving endurance. Creatine also serves as a high energy bond in nerve and muscle tissues to maintain ATP(Adenosine Triphosphate) levels during muscular contraction. ATP is the actual fuel used by your body which makes the muscles work, increasing your duration of muscular strength and stamina.
