Creactor™ rapidly enhances your muscle cells’ ability to regenerate Adenosine Triphosphate (ATP). ATP is your primary source of anaerobic energy, so you can recovery faster between sets. During high intensity training, ATP from muscle stores is utilized first. Once this store has been diminished, you need to start generating your own ATP.  At high intensities of exercise, this ATP production occurs with the breakdown of phosphocreatine in your muscles.
