Creatine monohydrate

Also known as Creatine
AEVIDENCE

Consistency over ceremony. No loading-phase folklore required.

The honest take
If the Formulary had a crown jewel, this is it. Creatine is the single most-studied sports supplement in existence — hundreds of trials, a safety record longer than your gym membership, and it costs almost nothing. Everything glossier on the shelf is negotiable; this isn't. The only real mistake men make is overthinking it: no loading phase, no cycling off, no exotic form beats plain monohydrate. Take it every day and forget about it.
What it is
The most-studied strength supplement there is — a compound your muscles use to recycle energy during short, hard efforts.
How it works
Your muscles run short, explosive efforts on a molecule called ATP, and they burn through it fast. Creatine tops up the reserve your body uses to regenerate ATP — so the last rep looks like the first, and there's a little more in the tank for the set after. Over weeks it also pulls water into muscle cells, which is part of why you look fuller on it.
What it does
Supports strength, power output and training performance when taken consistently. The work is in showing up daily, not in the timing.
Who it's for
Anyone who lifts, sprints, or wants their training to add up faster — which is most men here. Vegetarians tend to feel it most, since dietary creatine comes from meat. Genuinely universal; there's no real 'not for me' beyond preference.
How to use it
5 g daily, any time of day — in your shake, in water, doesn't matter. Consistency is the whole game: the reserve builds over two to three weeks and stays topped up as long as you keep taking it. Skip the loading phase; it just bloats some people and buys you nothing long-term.
What to expect
A slightly fuller, harder look within a few weeks as cells hold more water, and strength that creeps up across a training block. It isn't a stimulant — you won't 'feel' a dose. The results show in the mirror and the logbook, not in the first hour.
The research
Grade A, and it isn't close — decades of trials support strength, power and training performance, with an exceptional safety profile in healthy adults. The old 'creatine wrecks your kidneys' line comes from misreading a harmless rise in a lab marker (creatinine); it doesn't apply to healthy people. Read the FORM and the dose. Dicreatine malate (IGNITE) is not monohydrate: the salt itself is barely studied, and 1.5 g of it carries roughly a gram of creatine — a fraction of the 3–5 g the evidence is built on. The A grade belongs to monohydrate at a full dose, not to this.
