"Third party tested creatine" is searched about 1,300 times a month in the US, and "informed sport creatine" another 170. The people asking are mostly in two groups: buyers who want to know the tub holds what it says, and athletes who get drug-tested and need to know it holds nothing else. The words on the label do not tell either group which promise was made.
Google's AI answer for the question on 2 November 2026 listed Creapure alongside NSF and Informed Sport as a "certification", and treated NSF Certified for Sport and Informed Sport as the same thing. They are not. This page compares the programmes from their own published descriptions, read on 3 November 2026, and counts what the one public register this site could read held for creatine that day. It ranks no brand and no programme.
The programmes, side by side
| Programme (run by) | What it is | Banned-substance screen | Contents / contaminants | How often | Public register? |
|---|---|---|---|---|---|
| NSF Certified for Sport (NSF) | Certification | 290 substances | Label contents confirmed; contaminants via the contents standard | Lots tested and listed; facility audits annually or twice a year | Yes — lists products and tested lots |
| NSF/ANSI 173 (NSF) | Certification (contents standard) | Not a sport screen | Label contents, contaminants, microbiology, heavy metals | Annual testing and audits | Yes (separate listing) |
| Informed Sport (LGC) | Certification | More than 285 | Manufacturing review | Every batch before release, plus blind retail testing | Yes — refused automated reading |
| Informed Choice (LGC) | Certification | More than 285 | Manufacturing review | Monthly blind tests of retail samples, not every batch | Yes — refused automated reading |
| BSCG Certified Drug Free (Banned Substances Control Group) | Certification | More than 450 | Label claims and contaminants in its separate Certified Quality programme | Every finished lot, or ingredients monthly | Yes (client database) |
| Labdoor | Testing publisher | — | Buys products and publishes lab results with grades | When it tests; reports can expire | Yes — creatine page lists 12 reports |
| Creapure (Alzchem) | Ingredient brand, not a test | — | — | — | — |
Two other names turn up on creatine searches. USP Verified is a contents-and-manufacturing verification run by the US Pharmacopeia; its website refused automated requests on 3 November 2026, so this page reports none of its terms. Clean Label Project describes itself as testing products for heavy metals, pesticides and plasticisers that labels do not show; its programme page was not found at the address tried that day.
The column that matters most for a drug-tested athlete is the third, and the one that matters most for everyone is the last: a programme with a searchable register lets a buyer check a specific product, and a lot-based register lets them check a specific tub.
What each one actually promises
NSF Certified for Sport. NSF's certification page describes the route in steps: manufacturing-practice certification with audits annually or twice a year depending on grade, then contents testing to confirm the product "contains no unsafe levels of contaminants and meets the claims and contents shown on the product label", then testing "for 290 banned substances", a formulation and label review, and ongoing monitoring against the prohibited lists of the NFL, MLB and NSF's own Annex C. The certified listing names lots. The full two-programme explanation, and how to match a lot number, is on NSF-certified creatine.
NSF/ANSI 173. The contents half of the above, without the sport screen. A label that says "NSF certified" without "for Sport" usually means this.
Informed Sport. LGC, which runs a UK anti-doping laboratory, says Informed Sport "means every batch/lot of a product is tested prior to being released to the market", including every flavour, for "more than 285 substances banned in sport", with blind testing of retail samples after certification. It was developed in 2008 with UK Anti-Doping.
Informed Choice. Also LGC, with the same substance list, but LGC calls it "a global retail monitoring and quality assurance programme": after certification it buys retail samples "at least monthly" and blind-tests them. It does not test every batch. LGC describes it as designed for active people "who aren't necessarily subject to the strict doping measures of elite athletes".
BSCG Certified Drug Free. BSCG says the programme "tests every finished product lot, or monthly for ingredients, for an industry leading 450+ banned substances". Its label-claim and contaminant testing sits in a separate annual programme, Certified Quality, which BSCG says "is not designed for anti-doping".
Labdoor. A company that buys supplements, tests them and publishes grades. It certifies nothing; its creatine page on 3 November 2026 showed 12 product reports, 4 marked "Expired" and one marked "Upcoming". A Labdoor grade is a test result from one purchase on one date, not an ongoing programme.
Creapure. A trade name for creatine monohydrate made by Alzchem in Trostberg, Germany. It tells a buyer where the raw creatine came from. It is not an independent test of the finished product, and a tub made with it can carry any, or none, of the marks above. What the name does and does not guarantee is on Creapure explained.
What the one readable register held for creatine
NSF's Certified for Sport register returned its full listing on 3 November 2026. Counted the same way as this site's earlier count — rows carrying NSF's creatine product tag and with creatine in the product name:
| NSF Certified for Sport register | 2026-10-05 | 2026-11-03 |
|---|---|---|
| All product rows | 2,542 | 2,602 |
| Creatine rows | 184 | 184 |
| — of which gummies or chews | 39 | 46 |
Rows are per flavour and format, so one product in eight flavours counts eight times; brand names on the register were not merged for this count. The creatine total held steady while gummy and chew rows rose by seven — the format where the independent rounds below found the most trouble.
The Informed Sport and Informed Choice registers refused automated requests when this site tried them, as they had in October, so this page reports none of their listings. Where a brand profiled here claims one of those marks, the claim is reported on that brand's own page.
"Third-party tested", with no programme named
The phrase has no legal definition. Among the brands this site has read from their own stores and labels:
- Jocko Fuel says independent labs test every batch; no laboratory is named and neither NSF listing carries the brand.
- NativePath says it tests every production lot with an independent, accredited laboratory; no laboratory or result is published on the product page.
- Mindbodygreen publishes results for named lots — creatine measured 5.36 to 5.41 g against a 5 g claim — but names no laboratory and shows its heavy-metal results only as "Pass". One of its six creatine products, the electrolyte stick, is on the NSF sport register.
A published lot result is more than a bare claim, and a named programme with a searchable register is more than either: it is the only version a buyer can check against the tub in their hand. The full side-by-side of every brand profiled is the creatine label index.
What the independent rounds found
The best-known off-the-shelf check of creatine content looked at one format. In March 2024 NOW Foods — a supplement maker that sells creatine powder and so competes with every product it tested — bought 12 creatine gummy brands and measured their creatine by liquid chromatography, naming six as failing their label claim. It published no per-product figures. The survey, its conflict and its arithmetic problem are read in full on creatine gummies. It is the strongest practical argument for a named programme on a gummy: the format is harder to fill accurately than a scoop of powder, and a register entry is the only outside check a buyer can make.
For athletes who get drug-tested
A sport's anti-doping rules, not the supplement label, decide what counts. Programme marks reduce risk; none removes it, and under strict liability an athlete is responsible for what is in their sample. What WADA prohibits, compound by compound, is on WADA status by compound. Peptifact's third-party testing explainer covers the same questions for research peptides, a different market with no equivalent programmes.
Limits of this page
The programme descriptions are each organisation's own, read on one day; this site has not audited any of them. Two registers (Informed Sport, Informed Choice) and one programme site (USP) refused automated reading, so their rows rest on the organisations' descriptions only. The NSF count is a count of register rows, not of distinct products or brands. A mark on a tub is a claim until it is matched on the register.
