Informed Sport says every batch of a certified product is tested for more than 285 substances prohibited in sport. NSF’s own programme site says 280+ banned substances. BSCG says its Certified Drug Free programme screens 450+ substances and tests every finished product lot. On headline count BSCG claims the most; on batch policy, NSF’s readable pages do not say.
That is the short answer to “Informed Sport vs NSF Certified for Sport vs BSCG, which tests more substances”, and it is worth saying plainly that there is no news peg here. Nobody changed a rule this week. What changed is that we sat down on 11 September 2026 and read what each certifier publishes about itself, because the pages ranking for this question mostly quote each other, and two of them are a bot-block and a dead Shopify store.
Informed Sport vs NSF Certified for Sport vs BSCG: what each certifier says it screens
Every row below is the certifier’s own wording, read from the page linked, on 11 September 2026. Where a figure is one certifier describing another, it says so.
| Programme | Stated screen size | Stated batch or lot policy | Where we read it |
|---|---|---|---|
| Informed Sport (LGC) | “more than 285 substances prohibited in sport” | “EVERY product batch (including all flavour variants)” tested before release; database searchable by batch number | Informed Sport certification process |
| NSF Certified for Sport | “280+ banned substances” (from an NSF news teaser about IM8 on the programme site) | Not stated on the NSF pages this desk could read; BSCG describes it as “variable by product and manufacturer” | nsfsport.com |
| BSCG Certified Drug Free | “450+ substances” | “Every finished product lot” | BSCG comparison, 8 June 2026 |
Two caveats the table cannot carry. The NSF figure comes from a promotional teaser on NSF’s own site, not from a programme-rules page, because the nsf.org Certified for Sport page answered our fetch with a Cloudflare block. And the BSCG figures sit on a page whose whole purpose is to compare BSCG favourably with the other two; BSCG says its data “are based on program documentation”, and we have no reason to doubt it, but it is self-reported.
Why the numbers you see elsewhere do not match
The incumbents disagree with the certifiers, and with each other. Momentous, a brand that carries both marks and holds the top result, writes that Informed Sport screens “over 250 compounds”; the certifier’s own page says more than 285. BSCG’s comparison table gives NSF “290+ substances”; NSF’s own site says 280+. Neither gap is dramatic, and screen sizes grow over time, so an older number is probably just an older number. But it means the question “which tests more substances” has been answered on the first page of results with figures nobody dated or sourced.
For what it is worth, BSCG’s same table puts the Cologne List at approximately 150 substances and HASTA at 250+. Those are BSCG’s attributions; we did not read either programme’s own page.
Why the count is the wrong thing to compare
We made this argument on 11 August in our piece on certification being a batch claim, not a brand claim, and the three certifiers’ own pages make it again. A screen of 285 or 450 substances protects you only if the tub in your hand was in the screened batch. Informed Sport’s process page is explicit: after certification, every batch, every flavour, is submitted for testing before the product can be released, a retained unit is stored for the product’s shelf life, and blind retail purchases start at between one and four per year. BSCG states every finished product lot. NSF’s readable pages give you a lot-number search, which is the tool that matters, but do not tell you the rule behind it.
So the operative question for a tested athlete is not 280 versus 450. It is whether your batch number returns a result in the certifier’s database. The CELSIUS NSF story we ran on 26 August is a reminder that a mark on a can or a tub is a claim about enrolled products, and the database is where you check it.
One more thing the two certifiers whose pages address it say outright: none of this is regulatory approval. Informed Sport’s homepage says a label reading “Approved by WADA” is meaningless because WADA and national anti-doping bodies do not approve supplement products. BSCG’s page says testing reduces risk but cannot eliminate it. Certification is a private testing scheme with a public database, and that is exactly as much as it is.
Is NSF Certified for Sport better than Informed Sport?
Not on any measure the two certifiers publish. Informed Sport states more than 285 substances and testing of every batch before release. NSF’s programme site states 280+ banned substances and a lot-number search, but the NSF pages this desk could read on 11 September 2026 do not state how often lots are tested. For a tested athlete, the batch you hold being in the database is the deciding check, not the mark.
How many banned substances does Informed Sport test for?
Informed Sport’s own certification-process page says every batch of a certified product has been tested for more than 285 substances prohibited in sport, using LGC’s ISO 17025 accredited screen. BSCG’s June 2026 comparison quotes the same 285+ figure. The Momentous brand blog that ranks first for this comparison still says over 250 compounds, which is below what the certifier currently publishes.
Does NSF Certified for Sport test every batch?
NSF’s own pages do not answer that to this desk. The nsf.org programme page returned a 403 block to our fetch on 11 September 2026, and nsfsport.com, which we did read, carries a lot-number product search but no line stating a per-lot testing frequency. BSCG’s comparison describes NSF’s frequency as variable by product and manufacturer. That is BSCG’s description, not NSF’s, and we cannot verify it against NSF.
What is BSCG certification?
BSCG Certified Drug Free is a third-party banned-substance certification run by BSCG, whose co-founder and chief science officer is the anti-doping scientist Don Catlin. On its comparison page dated 8 June 2026, BSCG states the programme screens 450+ substances, tests every finished product lot, includes a GMP compliance review and lists certified products in a public database. Those figures are BSCG’s own, published on a page that also grades its rivals.
What to actually do with this
If you are tested, buy from a certified batch, look the batch number up on the certifier’s site, and keep the tub. The Lipofit recall earlier this month, where FDA’s notice reported lab analysis finding fluoxetine and DNP in the tablets, is the kind of thing a banned-substance screen exists to catch, and the kind of thing no headline count tells you about a specific tub.
Supplements are not evaluated by the FDA and are not intended to diagnose, treat, cure or prevent any disease. Nothing here is medical advice, and no certification mark is a guarantee of anything beyond what the certifier states it tested, in the batch it states it tested.
