Theres alot more to Creatine than you think...
Creatine helps your body produce more ATP (your musclesā main energy source), meaning you can push heavier weight and get more reps. Thatās direct strength progression.
"The most underrated supplement"
It really is that simple

The science behind it
Creatine pulls water into muscle cells (intracellular hydration), making muscles appear fuller while also creating an anabolic environment for growth.
Creatine increases phosphocreatine stores in your muscles, helping regenerate ATP your bodyās primary energy source for short, explosive movements like heavy lifts and sprints.
With more available energy during high-intensity efforts, you can lift heavier, push harder, and progressively overload the foundation of muscle growth.
By helping reduce muscle cell stress and supporting energy replenishment, creatine allows you to recover faster and maintain high performance across sessions.
