Momentous launches Signature Spec Creatine with tenfold tighter purity controls and PFAS screening

Published: 17-Jun-2026

The reformulated, pharmaceutical-grade product introduces six-stage independent testing and NSF Certified for Sport status, setting a new contaminant-screening benchmark as the first in Momentous' Signature Spec line

Utah-based nutrition company Momentous has announced the launch of Momentous Signature Spec Creatine — a reformulated version of its best-selling product.

The company called it a "major upgrade," saying the new product was "one of the highest quality creatine products in the history of the supplement category."

"Creatine is a proven daily essential for both body and brain, and when a supplement becomes part of your everyday routine, quality isn't optional," said Momentous CEO and co-founder Jeff Byers.

While the industry chased trends and ineffective formats, we focused on improving the creatine itself. We already had a market-leading product, but Momentous Signature Spec Creatine sets a whole new benchmark.

"This is The Momentous Standard in action, our relentless commitment to science, rigorous testing and raising the bar, because anyone investing in their health deserves to know they are getting real results."

The new Momentous Signature Spec Creatine promises ten times tighter purity controls than the industry's premium standard, as well as contaminant screening for PFAS and microplastics — neither of which the industry standards require.

Momentous added that the product will also be tested to meet two- to five-times tighter limits for lead, mercury and cadmium than the industry's premium standard.


It will be manufactured in a pharmaceutical facility and purified through an advanced reverse-osmosis water filtration process rather than by chemical washing, as in most commodity creatines, which Momentous said resulted in fewer residual impurities and a cleaner final product.

The reformulated product is then micronised into an ultrafine powder that mixes effortlessly into water without clumping, grit, or residue, ensuring every milligram in a serving is easily consumed.


Signature Spec Creatine is built to the brand's rigorous Momentous Standard, which it says sets it apart from industry norms through a unique six-stage independent testing process.

To eliminate contamination risks that often arise during transport, every batch is thoroughly verified across numerous markers, including microplastics, heavy metals and forever chemicals.

This testing is conducted by elite independent laboratories such as EuroFins, Light Labs and SuppCo's blind-purchase TESTED programme.

This extensive scrutiny has secured an NSF Certified for Sport designation, guaranteeing a clean, banned-substance-free product that represents the highest standard of supplement quality and transparency.

"Our commitment to The Momentous Standard doesn't always make things easy, but we believe it is the right thing to do for the customer," added Byers.

"To put that into perspective, even when we work with the highest-quality suppliers and apply some of the industry's most rigorous testing protocols, products can still fail third-party testing. When they do, they never reach our customers. We start over."

"We've always chosen the right path over the easy one. Creating Signature Spec Creatine wasn't a decision we were obligated to make; it was the only decision consistent with The Momentous Standard."

The supplement industry has a transparency problem. Brands test their own products, publish their own results and ask consumers to trust them.

"TESTED by SuppCo exists to verify those claims independently, by anonymously purchasing products directly from brand websites the same way that a customer would,” said Nick Michlewicz, co-founder of SuppCo.

Momentous Creatine has been verified TESTED by SuppCo, reflecting Momentous' commitment to transparency and confidence in its manufacturing standards.

The updated creatine formulation is the first product to feature the brand's new Signature Spec designation.

This designation represents the highest standard of quality in the Momentous portfolio, where the brand has enhanced formulation, sourcing and manufacturing to achieve a best-in-class product.

Creatine will be the inaugural product to receive this badge, with Whey Protein Isolate, Plant Protein, Omega-3, Fiber+ and more foundational products set to follow.
