The Signature Spec Difference™
Not All Creatine is Created Equal
Our Signature Spec™ Creatine wasn’t built to the industry standard, it was built to The Momentous Standard®.
The Purest Available
10-100x fewer impurities than the baseline
Hidden Impurities
Trace impurities undisclosed
Heavy Metals Tested & Minimized
2-5x tighter limits than other premium brands
No Heavy Metal Testing
Lead, arsenic, cadmium — heavy metal testing not required by the FDA
PFAS & Microplastics Testing
We pass with undetectable levels
PFAS & Microplastics Ignored
The FDA doesn't require testing for either
Purified With Reverse-Osmosis Water
No chemical washing
Washed With Chemicals
Standard production uses chemical rinses
Third-Party Testing & Certification
NSF for Sport®, Eurofins, Light Labs, SuppCo
No Outside Verification
Third-party testing isn't required
Unrivaled 6-Stage Testing Protocol
Quality claims are easy to make. Verifying them is harder. That’s why we go above and beyond what’s required by the FDA to guarantee quality at every stage—from raw material to the product on your shelf.
Expanded certificate of analysis (COA) verifying 24 parameters including potency, purity, heavy metals, microplastics, and chemicals.
Raw material samples from each production batch are verified by third-party labs (EuroFins and Light Labs) against our Signature Spec™.
Inbound verification at our packaging facility confirms that Stage 1 and Stage 2 are accurate before anything goes in the package.
Third-party verification of packaged goods on our COA for label claim accuracy, heavy metals, microplastics—beyond the industry standard.
Independent certification through NSF Certified for Sport® confirms every batch is free from contaminants and banned substances.
TESTED (a SuppCo certification) purchases products from us, just like a consumer would, to verify results against label claims.
THE BOTTOM LINE
The FDA requires manufacturers to test their own products against their own specs. Our protocol adds independent lab verification at four separate points, batch-level banned-substance certification, and a final off-the-shelf consumer purchase test — covering contaminants and accuracy checks the FDA doesn't require of anyone.

Frequently Asked Questions
Momentous® Signature Spec Creatine, simply put, is the cleanest creatine on the market verified by a testing protocol that goes far beyond the standard FDA requirements, including multiple third-party certifications and testing for microplastics and PFAS.
Our creatine is also supremely micronized resulting in an ultrafine powder, similar to powdered sugar. It mixes effortlessly into liquid, laying a foundation for a seamless daily routine.
Both. About 5% of your body's creatine is stored in your brain, where it fuels the same ATP energy system that powers your muscles. Research shows creatine supplementation supports working memory, reduces mental fatigue under stress, and protects cognitive function under conditions like sleep deprivation, heavy mental workload, and aging. It's increasingly recommended for high performers, peri- and post-menopausal women, and anyone investing in long-term brain health.
No, we no longer source our Creatine from Creapure. Our new Signature Spec™ Creatine is made in a pharmaceutical facility to a spec we own (called Signature Spec™) which is produced with tighter purity controls allowing for 10x fewer impurities than our previous creatine, 2-5x tighter heavy metal limits, and additional testing to validate undetectable levels of microplastics and PFAS.
Both deliver the same Signature Spec™ Creatine, so the decision comes down to lifestyle. Choose powder if you already have a daily shake or hydration routine you can add it to. Choose chews if you travel often, want something you can take without water, or simply prefer the convenience of grab-and-go. Many customers use powder at home and Chews on the road.
Signature Spec™ Creatine is available in powders starting June 16th, 2026 and will be available for Creatine Chews on July 1st, 2026.
Yes, you can take creatine daily indefinitely, and no, you don't need to cycle on and off. Cycling is a holdover from older supplement protocols and isn't supported by current research. Creatine works by maintaining saturated muscle and brain stores — when you stop, those stores gradually return to baseline over 4–6 weeks, and the benefits taper with them. For most people, the goal is sustained daily use as part of a long-term performance and longevity routine.
You bet it is! Not only is Signature Spec™ Creatine third-party tested, but it follows an unrivaled 6-stage testing & certification protocol leveraging 4 different independent agencies: Eurofins, Light Labs, NSF Certified for Sport®, and TESTED by SuppCo. The testing begins with raw materials and continues through to off-the-shelf packaged goods, ensuring that anytime the product changes locations it remains as pure as when it started.
