Quick Facts

Reference Sizes

250 g, 500 g, 1 kg, 200 capsules

Storage

Store dry at room temperature in a tightly closed container; avoid prolonged storage after mixing in acidic liquid

Solubility

Limited water solubility at room temperature; warm water improves dissolution but does not change total ingested dose

Catalog Description

Creatine monohydrate is the most extensively studied creatine form. A loading phase raises muscle stores quickly but is not required; lower daily intake reaches similar saturation more gradually. It is a nutrient supplement rather than a peptide or research drug.

Catalog descriptions reflect research context only. Not a medical claim or treatment recommendation.

Research Profile

Half-Life

A single plasma half-life is less relevant than muscle-store saturation and turnover; stores rise rapidly with loading or over approximately four weeks with 3 g/day

Onset

Muscle stores can approach saturation after 5-7 days of loading or about 3-4 weeks without loading

Administration Routes (Research)

Oral

Reported Research Effects

Increases intramuscular creatine and phosphocreatine
Supports repeated high-intensity exercise performance
Increases body water and often body mass

Reported Research Side Effects

Body-mass increase from water retention
Gastrointestinal discomfort with large single doses
Muscle cramping is not consistently supported in controlled evidence

Do not convert an amount between routes. Bioavailability, formulation, sterility, monitoring, and clinical context differ by route. Research-use context only; independently verify every cited source.

Research Notes

Current powders are commonly sold in 250 g 500 g and 1 kg containers; capsule products also exist. Community practice aligns with 3-5 g/day but is not needed to establish the evidence-based protocol.
