Momentous Dropped Creapure®. Here's What "Signature Spec" Actually Is.
⚡ Direct Answer: Is Momentous Still Creapure®?
No. Momentous stopped using Creapure® in June 2026. It now uses an in-house standard called Signature Spec™ — creatine made in a pharmaceutical facility to a specification Momentous owns. It remains NSF Certified for Sport, and Momentous has actually added testing (PFAS, microplastics, blind off-the-shelf purchase) that neither Creapure® nor NSF requires. This is not a safety downgrade. But if you bought Momentous because it was Creapure®, that reason no longer exists — and almost nobody has told you. Is it actually better? →
Momentous said this out loud, on its own product pages: "Momentous no longer sources our Creatine from Creapure®." Yet half the internet — retailer listings, "best creatine" lists, review sites, and until this week our own Creapure® database — still tells you it does.
What Actually Changed
In June 2026, Momentous announced a complete reformulation of its best-selling product. The headline nobody covered properly: Creapure® is gone.
| Momentous — Before | Momentous — Now (Signature Spec™) | |
|---|---|---|
| Creatine source | Creapure® (AlzChem, Germany) | In-house "Signature Spec" — a spec Momentous owns |
| Manufacturing | Standard premium production | Pharmaceutical facility |
| Purification | Chemical washing (industry norm) | Reverse-osmosis water filtration |
| NSF Certified for Sport | ✅ Yes | ✅ Still yes |
| PFAS testing | ❌ No | ✅ Yes (not required by NSF or Creapure®) |
| Microplastics testing | ❌ No | ✅ Yes (not required by NSF or Creapure®) |
| Blind off-the-shelf testing | ❌ No | ✅ SuppCo "TESTED" — bought anonymously like a consumer |
⚠️ The claims Momentous is making
- 10× fewer impurities than its previous creatine — and its previous creatine was Creapure®. Read that again: they're implicitly claiming to beat the standard they abandoned.
- 2–5× tighter limits for lead, mercury and cadmium than "the industry's premium standard."
- Non-detectable arsenic, cadmium, lead and mercury; 99.8% potency accuracy.
Is Signature Spec Actually Better Than Creapure®?
This is the question that matters, and the honest answer has two halves that point in opposite directions.
✅ Where it's genuinely stronger
- Six-stage testing across four independent labs — Eurofins, Light Labs, NSF, and SuppCo
- PFAS + microplastics screening — neither Creapure® nor NSF requires this. Almost nobody in the category does it.
- SuppCo's TESTED program buys the product anonymously off the shelf, like a customer would. That closes the loophole where a brand submits a pristine sample and ships something else.
- Still NSF Certified for Sport — every batch, banned substances, heavy metals, label accuracy
- Testing runs from raw material through to packaged goods, catching contamination in transit
⚠️ Where the skepticism is fair
- "A spec we own" — Creapure® is defined by an external body (AlzChem). Signature Spec is defined by Momentous. They set the bar they're clearing.
- "10× fewer impurities" is a self-comparison against their own prior product, using their own spec. No independent body has adjudicated that claim.
- Creapure® is a 30-year-old known quantity with a public DCD/DHT testing standard. Signature Spec is weeks old.
- Dropping a licensed premium ingredient usually lowers input cost — and the retail price didn't drop.
💡 Our read: the specification is self-defined, but the verification is not
That distinction is everything, and it's where most takes on this will go wrong.
Yes — Momentous wrote its own standard, and you should be skeptical of any brand that grades its own homework. But they didn't stop there. They kept NSF Certified for Sport (external, every batch), added three more independent labs, and — crucially — signed up for blind off-the-shelf purchase testing, which is the single hardest form of verification to game. A brand cheating its own spec would not invite an anonymous buyer to test the retail product. On the evidence available, this looks like a real upgrade rather than a cost-cutting exercise dressed as one.

The Real Problem: Almost Nobody Updated Their Pages
Here's what makes this worth an article rather than a footnote.
📌 We got this wrong too — and we've fixed it
Our own Creapure® brands database listed Momentous as a Creapure® product. That was wrong, and we've removed it — along with a correction notice on every affected page.
We're telling you this because we'd rather be the site that corrects itself in public than the site that quietly edits and hopes nobody noticed. But we're far from alone: retailer listings, "best creatine 2026" roundups, and even trade press articles still describe Momentous creatine as containing Creapure®.
Why this matters practically: Creapure® is one of the top reasons people choose a premium creatine. If you picked Momentous off a list that said "NSF + Creapure®," you bought it for a property it no longer has — and the list never told you.
⚠️ Check what you're actually buying. The switch is recent (June 2026). Retail stock, including on Amazon, may still be the older Creapure® formulation depending on how quickly inventory turns over. If it matters to you either way, check the packaging for the Signature Spec™ designation before you buy — and don't assume a listing description is current.
Is Momentous Creatine Still Safe? Yes.
Let's be clear, because a "brand drops premium ingredient" headline invites the wrong conclusion:
✅ Momentous Signature Spec Creatine — Verified Safe
- NSF Certified for Sport — every batch, 290+ banned substances, heavy metals, label accuracy
- Heavy metals non-detectable — arsenic, cadmium, lead, mercury
- 99.8% potency accuracy — what's on the label is in the tub
- PFAS & microplastics screened — beyond any standard certification
- Blind off-the-shelf verification via SuppCo TESTED
This is a sourcing change, not a safety story. We're not going to pretend otherwise to make the headline sting more. Anyone telling you Momentous "downgraded its creatine" is reading the press release, not the testing.
Product-line note: Signature Spec applies to Momentous Creatine Monohydrate (powder, travel packs) and Creatine Chews. Momentous also sells whey and plant proteins, omega-3s and other products — nothing on this page transfers to those lines. We never carry a result or a claim from one product line to another.
The Question Momentous Won't Answer: Why Didn't the Price Drop?
Creapure® is a licensed premium ingredient. It costs more. Dropping it should reduce input cost. Yet Momentous sits at roughly $0.50/serving — the top of the market.
| Brand | $/Serving | Certification | Annual (5g/day) |
|---|---|---|---|
| BulkSupplements | ~$0.13 | NSF Certified | ~$47 |
| NOW Sports | ~$0.19 | Informed Choice | ~$69 |
| Thorne | ~$0.47 | NSF Certified for Sport | ~$172 |
| Momentous Signature Spec | ~$0.50 | NSF for Sport + PFAS/microplastics | ~$183 |
⚖️ The unavoidable fact
Creatine monohydrate is chemically identical across brands. A 5g dose from Momentous and a 5g dose from BulkSupplements do exactly the same thing in your body. You are not buying a better molecule — you are buying verification. Momentous now offers the deepest verification in the category (PFAS, microplastics, blind purchase). Whether that's worth ~$136/year over BulkSupplements is a question only you can answer — but you should answer it knowingly.
✅ What We'd Buy
Momentous Signature Spec — if you want the deepest verification available (PFAS, microplastics, blind off-the-shelf testing) and price isn't the constraint.

Frequently Asked Questions
Is Momentous creatine still Creapure®?
No. Momentous states on its own product pages that it no longer sources its creatine from Creapure®. The switch to Signature Spec™ happened in June 2026. Most retailer listings, review sites, and "best creatine" roundups still say otherwise — they're out of date.
What is Signature Spec™?
It's Momentous's own creatine specification — a standard the company owns, produced in a pharmaceutical facility and purified with reverse-osmosis water filtration instead of chemical washing. Momentous claims 10× fewer impurities than its previous (Creapure®) creatine and 2–5× tighter heavy-metal limits, plus PFAS and microplastics testing that no standard certification requires.
Is Signature Spec better or worse than Creapure®?
The specification is self-defined; the verification is not. That's the honest answer. Momentous wrote its own standard — be skeptical of any brand grading its own homework. But it kept NSF Certified for Sport, added Eurofins and Light Labs, and signed up for SuppCo's blind off-the-shelf purchase testing — which is the hardest form of verification to game. A brand cheating its own spec wouldn't invite an anonymous buyer to test retail product.
Is Momentous creatine still safe?
Yes. Still NSF Certified for Sport (every batch, 290+ banned substances, heavy metals, label accuracy), with non-detectable arsenic, cadmium, lead and mercury and 99.8% potency accuracy. This is a sourcing change, not a safety story, and we're not going to inflate it into one.
I bought Momentous because it was Creapure®. What now?
Decide knowingly — that's the whole point of this article. If Creapure® specifically was your reason, that reason is gone; see our list of brands that still use it. If you bought it for rigorous third-party testing, that's intact and arguably deeper than before. And check your tub: recent stock should say Signature Spec™, but older Creapure® inventory may still be on shelves.
Which brands still use Creapure®?
Genuine Creapure® options include Myprotein Creapure®, Klean Athlete, Bare Performance Nutrition, and Dymatize. See our complete Creapure® brands database — recently corrected to remove both Momentous and Thorne, neither of which is actually a Creapure® product.
The Bottom Line
Momentous quietly dropped Creapure® in June 2026, and almost nobody told you. What replaced it — Signature Spec™ — is a standard Momentous wrote itself, which is exactly the kind of thing that should make you suspicious. Except they then submitted it to more independent scrutiny than before: NSF Certified for Sport, Eurofins, Light Labs, and blind off-the-shelf purchase testing, plus PFAS and microplastics screening that no certification in the category requires. The spec is self-defined. The verification isn't. On the evidence, this looks like a genuine upgrade rather than cost-cutting in disguise. But if Creapure® was your reason for buying Momentous, that reason is gone — and you deserved to hear it from someone.
