The Physics
Creatine is not magic. It is fuel. Understanding the mechanism is the first step to utilizing it efficiently.
The Energy Limit
Your muscles run on ATP (Adenosine Triphosphate). It is the volatile currency of biological work. Every contraction, every thought, every impulse burns ATP.
The problem is storage. Your intramuscular ATP stores are microscopic—sufficient for only 1-2 seconds of maximal exertion. Once these stores are depleted during high-intensity exercise (lifting, sprinting), force production plummets. This is the physiological failure point known as fatigue.
The Recharge Loop
This is where Creatine works. It is stored in the muscle as Phosphocreatine (PCr). PCr functions as a localized, high-speed charging dock.
When ATP is broken down into ADP (Adenosine Diphosphate) to release energy, Phosphocreatine immediately donates a high-energy phosphate group to the ADP, resurrecting it back into ATP in milliseconds. This process is anaerobic and alactic.
Supplementation increases intramuscular PCr saturation by 20-40%, effectively extending your high-intensity runtime before failure occurs.
Daily Intake Strategy
Creatine is not a stimulant like caffeine. It does not work instantly. It relies on tissue saturation. You must fill the tank before you can use the fuel.
The Loading Phase
While loading (20g/day) saturates muscles faster (5-7 days), it often causes bloating. We recommend the linear approach.
Daily Consistency
A steady 3g-5g daily intake saturates muscles fully within 30 days without digestive distress. Consistency is the only metric that matters.
Washout
If you stop taking creatine, stores slowly return to baseline over 4-6 weeks. You do not need to "cycle" off creatine.
Beyond Muscle: The Brain
The benefits of creatine extend beyond the squat rack. The brain is a metabolic furnace, consuming 20% of your daily energy despite representing only 2% of body mass.
Like muscle fibers, neurons rely on ATP for signal transduction. Emerging data suggests creatine supplementation can buffer cerebral energy deficits, particularly during sleep deprivation, hypoxia, or complex cognitive tasks. It is fuel for the machine, regardless of the tissue.
