Measure the dose
Typical Creatine Monohydrate dose is 5000 mg. Use a weight-based calculator for individual adjustments.

Cycle if needed
No cycling required; continuous daily dosing is standard. Optional 20 g/day loading for 5 to 7 days to reach saturation faster.

Monitor for side effects
Watch for: water retention; mild GI upset at loading doses; weight gain (2 to 4 lb from intracellular water). Stop or reduce dose if tolerability breaks down.
Why this dose
Donates a phosphate group to ADP via creatine kinase, regenerating ATP during high-intensity, short-duration efforts.
The typical 5000 mg dose is the figure most commonly used in published protocols for Creatine Monohydrate. Treat the label as a starting point: body weight, training status, sleep, diet, and concurrent medications all shift the effective dose-response curve in real users.
How to administer
Creatine Monohydrate is administered via the oral route. Oral dosing is straightforward: take with water, with or without food unless specifically noted.
Onset of action runs around 1 weeks after administration. Plan the administration window so that peak effect lines up with whatever outcome you are dosing for, whether that is training, sleep, or symptom coverage.
Half-life note: Plasma half-life ~3 hours; intramuscular phosphocreatine saturation persists for weeks after loading
Cycling and tolerance
No cycling required; continuous daily dosing is standard. Optional 20 g/day loading for 5 to 7 days to reach saturation faster.
Effects to expect at typical dose
- Increases anaerobic strength and power output by ~5 to 15% across multiple training studies
- Adds ~1 to 2 kg of lean body mass over 4 to 12 weeks, partly intracellular water and partly true tissue gain
- Improves 1-rep max on bench and squat by ~5 to 10% versus placebo in resistance-trained adults
- Cognitive benefit appears mainly under sleep deprivation or high mental load, less so in well-rested individuals
- Saturation reached in ~28 days at 3 to 5 g/day, or ~5 to 7 days with a 20 g/day loading phase
- No evidence of renal harm in healthy adults across long-term studies; caution in pre-existing severe renal disease
Best-graded outcomes
- A 1RM strength (bench, squat) : 5 to 15% above placebo (Resistance-trained adults).
- A Lean body mass : 1 to 2 kg gain (water plus tissue) (Trained adults, 4 to 12 weeks).
- A High-intensity exercise capacity : 5 to 15% improved power output (Anaerobic and sprint efforts).
Side effects and interactions
Common side effects
- water retention
- mild GI upset at loading doses
- weight gain (2 to 4 lb from intracellular water)
Notable interactions
- nephrotoxic drugs (NSAIDs, cyclosporine) (moderate): theoretical additive renal strain in at-risk patients
- caffeine (high-dose acute) (minor): mixed data on ergogenic interference; chronic use appears compatible
Lists above cover commonly reported and well-characterized items. They are not exhaustive: review the full Creatine Monohydrate profile and discuss with a clinician familiar with your medication list before starting, particularly if you are on prescription therapy or have a chronic condition.
