Directly increases levels of adenosine triphosphate (cellular energy)
Increases blood flow to muscle cells
Increases ATP by supplying direct precursor, cAMP
Increases testosterone production
Increases blood flow (for increased “pump”)
Increases oxygen efficiency
Significantly decreases fatigue
Allows for more efficient energy production during anaerobic activity
Facilitates fatty acid and amino acid conversion into muscle [...]
