    Creatine Phosphate Restoration

    Faster ATP regeneration for repeated high-intensity efforts.

    TL;DR

    Creatine monohydrate is one of the best-evidenced supplements in existence: 3-5 g daily raises muscle phosphocreatine roughly 20% and improves repeated high-intensity output. Nothing else in this category comes close.

    Why It Matters

    Phosphocreatine is the rate-limiting energy buffer for efforts under 30 seconds. Higher stores improve sprint repeatability, strength training volume, and — in older adults — power and functional capacity.

    How to Measure

    Biomarkers

    Repeated sprint decrement
    1RM strength
    Lean body mass

    Optimization Protocol

    Creatine monohydrate 3-5 g daily, every day, timing irrelevant. Optional 20 g/day loading for five days saturates stores faster. Pair with resistance training; expect 1-2 kg of water-driven weight gain in the first fortnight.

    Frequently Asked Questions

    What does creatine phosphate actually do?
    It regenerates ATP within seconds during maximal effort, which is why it matters for sprints, jumps and heavy sets rather than endurance work.
    What is the best dosing approach?
    Either 3-5 g/day continuously, which saturates muscle stores in 3-4 weeks, or a loading phase of 20 g/day split into four doses for 5-7 days followed by 3-5 g/day.
    Is monohydrate still the best form?
    Yes. Creatine monohydrate has the largest evidence base and no alternative form has demonstrated superiority, despite costlier marketing claims.
    Does it cause water retention or kidney problems?
    An initial 1-2 kg gain is mostly intramuscular water. In people with healthy kidneys, long-term trials up to 5 years show no renal harm; existing kidney disease warrants medical advice.
    Do some people not respond?
    Yes. Those with already high muscle creatine, often higher meat eaters, show little further increase. Vegetarians typically respond most strongly.
    Does timing matter?
    Total daily intake matters far more than timing. Taking it with a carbohydrate-containing meal may slightly improve uptake.
