Third-party testing for creatine: what the seals mean

Independent testing for creatine isn't one program — it's shorthand for several different ones, each checking somewhat different things. NSF's Certified for Sport program screens for banned substances and label accuracy; USP's Verified Mark checks label accuracy and contaminant limits; Informed Sport tests every batch against the anti-doping list; Creapure is a purity mark for the raw material, not the finished product. Our label doesn't carry any of these seals, and we hold none of them for this product.

NSF's Certified for Sport program

NSF International runs a program called Certified for Sport that tests finished products for roughly 290 substances banned by major sports organizations — stimulants, steroids, diuretics, masking agents and similar categories — plus verifies the label's claimed ingredients and amounts match what's actually in the product. It's the program most often referenced by professional and college sports organizations specifically because of the doping-risk angle, not because it's a general purity or safety seal beyond that scope.

USP's Verified Mark

The U.S. Pharmacopeia runs a program called the Verified Mark, which checks that a product contains the ingredients and amounts listed on the label, that it doesn't contain harmful levels of specified contaminants, and that it was manufactured following current good manufacturing practices. USP reviews a relatively small number of products a year compared with the size of the supplement market, so a product without the mark isn't necessarily lower quality — it may simply not have gone through the program.

Informed Sport

Run by LGC, Informed Sport tests every manufactured lot of an enrolled product against the World Anti-Doping Agency's prohibited list before it ships, rather than testing a sample once. Like NSF's program, it's built around doping risk for competitive athletes specifically, not a general-purpose purity or safety claim.

Creapure

Creapure is a purity trademark for creatine monohydrate itself, manufactured in Germany to a specified process, licensed to supplement brands as a raw-material ingredient. A product made with Creapure is telling you something about where the raw creatine came from, not necessarily that the finished tub or capsule has itself gone through NSF, USP or Informed Sport screening — those are separate questions about the finished product.

Where our label stands

Electric Tiger Creatine Monohydrate doesn't carry an NSF, USP, Informed Sport, or Creapure mark, and we hold none of these for this product. That's the honest answer, not a claim dressed up to sound like something it isn't — see how to choose a good creatine for where this sits in the full label checklist.

Questions people ask

Is your creatine independently tested?

No. We don't hold NSF's Certified for Sport mark, USP's Verified Mark, Informed Sport enrollment, or Creapure certification for this product, and we're not going to imply otherwise.

What does NSF certification mean for creatine?

It means the specific product was screened for roughly 290 substances banned by major sports organizations and that its label claims were checked — a program built for competitive athletes' doping risk, run by NSF International.

Is Creapure the same as independent testing?

No. Creapure is a purity trademark for the raw creatine monohydrate itself, made in Germany to a specified process. It's a statement about the ingredient's origin, not an independent check of the finished product a brand packages and sells.

Do I need independently tested creatine?

It matters most to competitive athletes subject to drug testing, where NSF's or Informed Sport's screening reduces the risk of an inadvertent positive from a contaminated product. For general use, it's one item on a longer checklist — see how to choose a good creatine for the rest of it.
