The supplement runners skip — and shouldn't.

If you came from running, you've probably dodged creatine for fear of 'water weight.' Here's the truth — and what it actually does once you start lifting.

The myth

You've heard creatine 'makes you hold water.' The little water it pulls goes inside the muscle — where it helps it work. You're not getting puffy. You're getting stronger.

The lift

More reps left on the last hard set. Over weeks that's more total work — and more work is exactly what builds strength.

The recovery

Helps refill the fast energy your muscles burn, so you bounce back quicker between hard sessions.

The bonus

Newer research even points to cognitive benefits on low-sleep days — the one supplement that supports the body and the mind. The easiest win you can add to your routine.

Creatine helps replenish ATP — the fast energy your muscles use for hard efforts — supporting strength, power output, and recovery.

what's inside

One ingredient. Dosed right.

The most-proven supplement in fitness doesn't need a blend. It needs to be the real thing, at the real dose, and clean. 5 g per serving, 30 servings per tub.

5 g
Creatine Monohydrate

Will creatine make me hold water and feel bloated?

The small amount of water creatine draws goes inside the muscle cell, not under your skin. That's a good thing — it's part of how it helps the muscle perform. Most people don't notice any puffiness; they notice they're stronger.

Do I need to do a loading phase?

No. Loading just fills your stores a few days faster. Take 5g a day and you'll be fully saturated in about 3–4 weeks with zero stomach drama. Simpler is fine.

I'm a runner — do I even need creatine?

If you're starting to lift, yes. Creatine fuels short, hard efforts — the exact thing strength work demands. It won't weigh down your running, and it'll help you get more out of every session in the gym. It's the first supplement worth taking once a barbell enters the picture.

Is creatine safe? What about my kidneys?

Creatine has one of the strongest safety records of any supplement, studied for over 30 years. In healthy people, research consistently shows no harm to kidney function. If you have a pre-existing kidney condition, check with your doctor first — as with anything.

Monohydrate or one of the 'advanced' forms?

Monohydrate. The HCl, buffered, and liquid versions cost more and have never been shown to beat plain monohydrate. The most-researched, most-proven form is also the cheapest. We're not going to charge you extra for a worse deal.

What does micronized mean?

Just a smaller particle size. It mixes into water more cleanly with less grit and tends to be easier on the stomach. Same creatine monohydrate, nicer to actually drink.

Is creatine a steroid?

No. Creatine is a compound your body already makes and you get from food like red meat and fish. It's not a hormone and not a steroid — it just tops up a system you already run on.

When should I take it?

Whenever you'll remember. Creatine works by keeping your stores full over time, not by timing — so there's no magic window. Many people take it with their morning ATP or a post-workout shake simply out of habit.

Is it vegan?

Yes. Our creatine is synthetically produced (not animal-derived), so it's suitable for vegans and vegetarians — who often benefit the most, since they get less creatine from food.

Can I really get it for free?

Two ways to buy. Grab it on its own here for $29.99 — or $25.49 a month on Subscribe & Save. Or get it free: subscribe to Substrate ATP, our flagship, and a pouch ships free with every order for as long as you stay subscribed. We cover the basic everyone should be on; you invest in the upgrade you feel. Cancel anytime.
