What to Look for in a Third-Party Tested Creatine Gummy

"Third-party tested" is on a lot of supplement labels. Most of them mean different things by it. Some mean the raw material was tested once before manufacturing. Some mean a single batch from two years ago went to a lab. Some mean nothing verifiable at all.

If you're choosing a creatine gummy based on testing claims, you need to know what you're actually evaluating. Here's the framework.

What third-party testing actually means

A supplement is genuinely third-party tested when an independent laboratory — one with no financial stake in the outcome — has tested the finished product and confirmed it contains what the label claims.

The word "independent" is doing a lot of work in that sentence. In-house testing, where a brand tests its own product in its own facility, is not third-party testing. It's self-reporting, and it removes the independence that makes any verification meaningful.

Third-party testing requires three things:

  • An accredited external laboratory
  • Testing of the finished product (not just raw ingredients)
  • A published Certificate of Analysis (COA) you can access

If any one of these is missing, the "tested" claim is incomplete.

The four things to check on any brand

1. Which laboratory?

Not all labs are equal. Look for labs that are:

  • Nationally accredited (NATA in Australia, ISO 17025 internationally)
  • Recognised in the sports supplement industry
  • Willing to have their name on a publicly accessible COA

Recognised names include Eurofins, Informed Sport, NSF International, and HASTA (Human and Supplement Testing Australia). Eurofins is one of the world's largest food and supplement testing networks, with strict accreditation requirements. HASTA is specifically relevant in the Australian market for athletes — HASTA certification means the product has been tested against the World Anti-Doping Agency prohibited list.

If a brand says they're "tested" but won't name the lab, treat the claim as unverified.

2. What was actually tested?

There's a meaningful difference between testing the raw ingredient and testing the finished product.

A manufacturer might source pharmaceutical-grade creatine monohydrate powder that tests perfectly. But once that powder is combined with gelling agents, sweeteners, flavours, and processed into gummy form — and then split across thousands of units per batch — the delivered dose per gummy can vary.

The only test that verifies what you're actually consuming is a finished product test: the actual gummies, sampled from a production batch, tested by an independent lab for creatine content per unit.

Ask specifically: was the finished product tested, or just the raw material?

3. Is the COA batch-specific and current?

A Certificate of Analysis that covers one batch from the brand's initial launch does not verify current production.

Supplements are manufactured in batches. Each batch can vary based on equipment, materials, and conditions. A COA is only valid for the specific batch it was drawn from. If you're buying a product manufactured in 2025 and the only published COA is from 2022, you have no verified data on what you're buying.

What to look for:

  • A batch number on the COA that matches (or can be matched to) product on sale
  • Test date within the last 12 months
  • Multiple COAs published over time, showing ongoing testing — not a single historic document

4. What does the COA actually show?

Open the COA and read it. Specifically:

Creatine monohydrate per serve (mg) — Compare this to the label claim. If the label says 5g per serve (4 gummies), the COA should show approximately 1,250mg per gummy, or 5,000mg per serve. Results significantly below label claim indicate underdosing.

Percentage of label claim — Some labs report this directly. Industry standard is 90–110% of label claim. Results below 90% are underdosed; results above 110% suggest batch inconsistency.

Heavy metals screen — A thorough COA will test for lead, arsenic, cadmium, and mercury. Not all do, but it's a marker of a brand that takes testing seriously.

Prohibited substances — For athletes subject to anti-doping rules, HASTA or Informed Sport certification specifically includes a prohibited substance screen.

The recall context

In 2024, independent testing reported that at least one major Australian creatine gummy brand had been found to contain significantly less creatine than advertised. The resulting recall was covered nationally.

This matters because it demonstrates that underdosing is a real, documented problem in the category — not a theoretical risk. It happened to a widely distributed, visible brand. The only consumer protection against it is a COA from an independent lab on the finished product.

Green flags vs red flags

Green flags

  • Named lab (Eurofins, HASTA, Informed Sport, NSF)
  • Finished product tested (not just raw ingredients)
  • Batch-specific COA, current within 12 months
  • Multiple COAs published over time
  • COA accessible directly on the product page, not gated behind a contact form

Red flags

  • "Tested" on the label with no lab named
  • COA available only "on request" — opacity suggests they're not testing routinely
  • Single COA with no batch number or a batch number from years ago
  • In-house testing cited as verification
  • Dose per serve buried under a "proprietary blend" designation

How Cunnies is tested

Each production batch of Cunnies Creatine Gummies is tested by Eurofins — twice per batch, independently. The tests confirm 5g of creatine monohydrate per serve (4 gummies). The COA is published on each product page, batch-specific, and updated with each new production run.

HASTA certification is in progress. In the meantime, the Eurofins COA is the verification. It's there because anyone buying should be able to check it before purchasing — that's the standard we hold ourselves to.

The short version

When evaluating any third-party tested creatine gummy:

  1. Name the lab — if they won't, the claim is unverifiable
  2. Confirm finished product was tested, not just raw ingredients
  3. Check the COA is batch-specific and recent
  4. Read the actual mg per serve and compare to the label

Our creatine gummies are batch-tested at 5g per serve. The COA is on the product page. Start there.
