Creatine for Men: Dose by Body Weight, Hair, Testosterone
Not medical advice. This summarizes randomized trials and meta-analyses, the labels manufacturers file with the NIH, and current Amazon prices. Men with kidney disease should ask a clinician before starting creatine.
Quick answer
Men take 3 to 5 g of creatine monohydrate a day, or 0.1 g per kilogram: 8.0 g at 80 kg, 10.0 g at 100 kg. That is the dose behind the evidence, and the evidence in men is the strongest in the literature: with resistance training, creatine added 1.1 kg of lean mass in a 2022 meta-analysis, and men specifically gained 1.46 kg. The two worries men search for, hair and testosterone, rest on one 2009 hormone study; the only trial that measured hair directly, in 2025, found nothing.
Buy plain monohydrate, 5 g a scoop, and skip the “men’s” formulas. On the 1,200 creatine labels filed with the NIH, monohydrate sells at a median 5 g per serving while hydrochloride sells at 2 g and buffered at 1.5 g, for more money and no evidence of an advantage. Optimum Nutrition Micronized Creatine Monohydrate is $0.27 per 5 g; Thorne Creatine is NSF Certified for Sport for anyone drug-tested. See the census →

The dose for men, by body weight
The International Society of Sports Nutrition’s position stand supports 3 to 5 g of creatine monohydrate a day as the maintenance dose for adults, with an optional loading phase of about 0.3 g per kilogram a day for 5 to 7 days to saturate muscle stores in a week rather than a month (Kreider 2017, PMID 28615996). The same authors’ review of common questions puts the maintenance dose as 3 to 5 g or 0.1 g per kilogram of body mass (Antonio 2021, PMID 33557850), which is the useful rule for men, because muscle creatine capacity scales with muscle mass and men are, on average, heavier.
| Body weight | Standard maintenance | 0.1 g/kg rule | Optional loading, daily for 5–7 days | Scoops of a 5 g powder (0.1 g/kg) |
|---|---|---|---|---|
| 60 kg (132 lb) | 3–5 g | 6.0 g | 18 g as 4 × 5 g | 1 |
| 70 kg (154 lb) | 3–5 g | 7.0 g | 21 g as 4 × 5 g | 1.5 |
| 80 kg (176 lb) | 3–5 g | 8.0 g | 24 g as 4 × 6 g | 1.5 |
| 90 kg (198 lb) | 3–5 g | 9.0 g | 27 g as 4 × 7 g | 2 |
| 100 kg (221 lb) | 3–5 g | 10.0 g | 30 g as 4 × 8 g | 2 |
| 110 kg (243 lb) | 3–5 g | 11.0 g | 33 g as 4 × 8 g | 2 |
Loading is a convenience, not a requirement: a meta-analysis of ingestion strategies in older adults found that higher-dose creatine, with or without a loading phase, produced significant leg-press gains, and that taking creatine only on training days still raised lean mass and strength (Forbes 2021, PMID 34199420). Timing barely matters; consistency does. Take it with a meal, any time of day, every day including rest days. The two rules diverge for bigger men: 5 g is 0.05 g per kilogram at 100 kg, half the body-weight rule, so a heavy man who plateaus on one scoop has room to take two; the position stand’s safety review covers doses far above that, up to 30 g a day for five years without harm in healthy adults (Kreider 2017). That is the only man-specific adjustment worth making, and the shelf below shows why the form matters more than the brand.
What creatine does for men: strength, mass, and the years after 50
The strength and lean-mass literature was built largely in young men, and the sex breakdown shows why the results read the way they do. A 2022 meta-analysis of randomized trials found creatine increased lean body mass by 0.68 kg across all designs and by 1.1 kg when paired with resistance training, regardless of age; without exercise it added nothing significant. Men on creatine gained 1.46 kg of lean mass, against a non-significant 0.29 kg in women (Delpino 2022, PMID 35986981). The mechanism is not anabolic: more phosphocreatine in the muscle lets you complete more high-intensity work in each session, and the training does the rest, which is why creatine without training does nothing measurable.
After 50 the case gets stronger, not weaker. A meta-analysis of 22 randomized trials in 721 older adults (mean ages 57 to 70) found creatine during resistance training added 1.37 kg of lean tissue over placebo and improved both chest-press and leg-press strength (Chilibeck 2017, PMID 29138605). Muscle loss with age is a functional problem before it is a cosmetic one, and creatine plus lifting is one of the few interventions with a pooled effect on it. The creatine for seniors guide covers the dose and the falls evidence.
The brain evidence is more contested and men search for it less: a 2023 meta-analysis found a small benefit to memory, larger in older adults (Prokopidis 2023, PMID 35984306), while a 2024 review argues the cognition literature fails to support the theory behind it (McMorris 2024, PMID 38582412). Buy creatine for the muscle; treat any cognitive effect as a possible bonus.
Hair, DHT and testosterone: one study against a direct trial
The hair-loss worry has a single source. In 2009, 20 college rugby players took creatine for three weeks in a double-blind crossover: after 7 days of loading, dihydrotestosterone rose 56% and stayed 40% above baseline after 14 days of maintenance, and the DHT-to-testosterone ratio rose 36% then 22% (van der Merwe 2009, PMID 19741313). Testosterone itself did not change. The study did not measure hair, and no study before or since has reproduced the DHT rise.
The direct test came in 2025: a 12-week randomized controlled trial in healthy young men, 38 completing, measured total and free testosterone, DHT and hair-follicle health before and after. There were no group-by-time effects for any hormone or any hair outcome; total testosterone rose and free testosterone fell in both groups by similar amounts, independent of creatine (Lak 2025, PMID 40265319). The reviews of creatine myths reach the same conclusion: no evidence that creatine causes hair loss, and creatine is not an anabolic steroid and does not raise testosterone (Antonio 2021; Antonio 2025, PMID 39720835). A man with a strong family history of baldness who wants to be cautious can take the maintenance dose without loading; that is the only concession the data suggest.
Kidneys, creatinine and the blood test
Creatine breaks down to creatinine, and serum creatinine is the number a routine kidney panel uses to estimate filtration. A man taking creatine will often show a slightly higher creatinine, which a doctor who does not know about the supplement can read as reduced kidney function. It is a measurement artefact, not damage: in a double-blind trial, 18 resistance-trained men loaded at 0.3 g per kilogram for 7 days and had 41 blood and urine markers measured 30 days later, with no change in renal or hepatic function and no adverse events (Almeida 2020, PMID 32597619). The position stand reaches the same verdict across the longer trials (Kreider 2017). Tell your doctor you take creatine before a blood test, and if you already have kidney disease, ask first.
We read 1,200 creatine labels: buy the form that is sold at the dose
Original research1,200 creatine labels from the NIH Dietary Supplement Label Database (2,412 on the market), 969 with a parseable creatine quantity and 788 with daily directions, read for creatine per serving and per day by chemical form. Every figure was recomputed in both halves of the read order; 2 of 4 findings held and only those are printed as statistics.
Monohydrate is the only form sold at the studied dose. Across the 1,200 labels, creatine monohydrate products sit at a median 5 g per serving; hydrochloride at 2 g, buffered creatine at 1.5 g, and magnesium chelate at 0.6 g. The premium forms are not sold as a smaller dose because less is needed; there is no trial showing any of them beats monohydrate gram for gram, and the buffered form failed to raise muscle creatine more than monohydrate in a head-to-head trial (Jagim 2012, PMID 22971354). A man buying by the scoop rather than the gram pays more for less.
| Item | Value ( g) |
|---|---|
| Creatine monohydrate (n=599) | 5 g |
| Creatine HCl (n=110) | 2 g |
| Buffered / Kre-Alkalyn (n=43) | 1.5 g |
| Magnesium chelate (n=39) | 0.6 g |
| Studied dose, low end | 3 g |
The directions add up to a normal dose. The median label serving is 3 g and the median day as directed is 3.5 g, because 868 of the 1,170 labels with directions call for one serving a day and the rest for two or more; that the directed day exceeds the serving held in both halves. Two labels in the census are worth knowing by name, as records rather than statistics: APS’s “Creatine Monohydrate 500g” prints 500 g on the front and 5 g on the panel, the tub weight against the dose, and Nutricost Women’s “Creatine 3 g Peach Mango” prints 3 g on the front and 2.3 g on the panel. Gendered creatine is a marketing category: the molecule and the dose are the same, and the women’s guide makes the same point from the other side.
How we read the labels, and what did not hold
Method, 969 labels with a parseable dose: creatine quantity per Supplement Facts serving; daily dose = serving x maximum daily servings; form from the row name and declared forms. Split-half validation: median dose as directed exceeds per-serving; Creatine monohydrate is dosed above the alternatives held; not printed as statistics: most of the market sells above the typical dose; a large share sells above the studied range. The census is published as open data at /creatine/forms-compared.json (CC BY 4.0). What it cannot tell you: whether the powder matches its label (see the gummy lab tests for the one format where it often does not), or how much of each sells.

Safety, briefly
Creatine monohydrate at 3 to 5 g a day is among the most-studied supplements in existence, with no medically significant adverse effects reported in healthy adults across decades of trials (Kreider 2017). Expect 1 to 2 kg of early weight gain, which is water in muscle, not fat; the myths reviews find no evidence for cramping, dehydration or fat gain (Antonio 2021). Stomach upset on loading doses resolves by splitting them. The one real caution is kidney disease, and the one real nuisance is the creatinine blood test.
Frequently asked questions
How much creatine should a man take per day?
3 to 5 g of creatine monohydrate a day, every day, or about 0.1 g per kilogram of body weight: 7.0 g at 70 kg, 9.0 g at 90 kg, 11.0 g at 110 kg. Bigger men sit at the top of the range because muscle creatine stores scale with muscle mass. A loading phase of 0.3 g per kg a day for 5 to 7 days (24 g a day at 80 kg, split into four doses) fills the stores in a week instead of three to four; it is optional, and the position stand treats it that way.
Does creatine cause hair loss in men?
The worry comes from one 2009 crossover study in 20 college rugby players, where three weeks of creatine raised dihydrotestosterone by 56% after loading and 40% above baseline on the maintenance dose; it did not measure hair. The only trial to measure hair directly, a 12-week randomized controlled trial in 38 young men published in 2025, found no effect of creatine on DHT, on the DHT-to-testosterone ratio, or on hair growth. One unreplicated hormone shift against a direct null trial: the evidence does not support the hair-loss claim, and no study has ever shown creatine causing baldness.
Does creatine raise testosterone?
No. Trials that measured total and free testosterone found the changes over time were the same with creatine and placebo; the 2025 hair trial saw both groups' total testosterone rise and free testosterone fall by similar amounts, independent of supplementation. Creatine is not an anabolic steroid and does not act on the androgen system; the strength gains come from more phosphocreatine in the muscle, which lets you do more work in training.
How much muscle does creatine add for men?
In a 2022 meta-analysis pooling trials with and without exercise, creatine added 0.68 kg of lean mass overall and 1.1 kg when combined with resistance training; men gained 1.46 kg against a non-significant 0.29 kg in women. Part of the early number is water drawn into muscle, and the rest depends entirely on training: creatine without exercise added nothing measurable in that analysis.
Is creatine safe for the kidneys?
In healthy men at the standard doses, every controlled study that has looked says yes. A double-blind trial in resistance-trained men loaded at 0.3 g per kg for 7 days and tracked 41 blood and urine markers 30 days later: no change in renal or hepatic function. Creatine raises blood creatinine because more creatine is being turned over, which can mislead a routine kidney test; tell the doctor you take it. Men with existing kidney disease should ask before starting.
Which creatine should men buy?
Plain creatine monohydrate powder, 5 g a scoop, from a brand that tests. On the 1,200 NIH creatine labels we read, monohydrate products sit at a median 5 g per serving; hydrochloride labels at 2 g and buffered at 1.5 g, at higher prices per gram with no evidence of superiority. Optimum Nutrition Micronized Creatine Monohydrate costs $0.27 per 5 g; Thorne Creatine is NSF Certified for Sport for anyone drug-tested.
