Phosphocreatine

Phosphocreatine is a natural energy storage molecule found in muscles. It acts like a quick-release reserve, helping to regenerate ATP—the main energy source for muscle contractions—during intense activity. When muscles need rapid energy, phosphocreatinedonates its phosphate group to ADP, converting it back into ATP. This process provides immediate energy support for short bursts of activity, such as sprinting or heavy lifting. Overall, phosphocreatine helps maintain muscle performance and delays fatigue during high-intensity efforts.
