Creatine monohydrate supplementation (5g/day for 5-7 days, followed by 3-5g/day maintenance) significantly increases intramuscular creatine and phosphocreatine stores, leading to enhanced high-intensity exercise performance, greater training adaptations, and increased lean body mass in athletes.

Take 5 grams of creatine monohydrate four times a day for 5-7 days to saturate your muscles, then switch to 3-5 grams daily to maintain levels. This is the most proven supplement for increasing strength and power output. It is safe, legal, and does not cause kidney damage or cramping as commonly feared.

StrongSupportsVERY_HIGH confidence
Studies have consistently shown that creatine supplementation increases intramuscular creatine concentrations which may help explain the observed improvements in high intensity exercise performance leading to greater training adaptations... The most effective way to increase muscle creatine stores is to ingest 5 g of creatine monohydrate (or approximately 0.3 g/kg body weight) four times daily for 5–7 days... Once muscle creatine stores are fully saturated, creatine stores can generally be maintained by ingesting 3–5 g/day
