Which pre-workouts are NSF Certified for Sport? On 15 September 2026, NSF’s own certified-product database listed pre-workout powders from 1st Phorm (Megawatt), ATHLEAN-RX (X-Cite), Cellucor (C4 Sport), ZOA+, Klean Athlete, Thorne, Momentous, Garden of Life, Proven4, Podium, Bare Performance Nutrition and roughly a dozen smaller brands, each certified per listed flavour SKU rather than per brand.
There is no news peg; the date is the date this desk read the NSF certified-product listing.
The NSF Certified for Sport pre-workout list, as NSF shows it
The category filter on NSF’s page did not apply on our read; the page said it was returning all products. So this roster is a name search of the full database, and a certified pre-workout named without pre-workout wording can slip through. The counts are NSF’s own, duplicates included.
Why the flavour count matters more than the brand name
X-Cite has ten rows; LTH has six, two apparently duplicates. That is the point of the mark: certification attaches to the listed SKU and tested lot, the argument in our piece on certification as a batch claim, and NSF’s page is the proof. A flavour not on the list is not covered.
The C4 rows cut the other way. Under the C4 heading the database also carries C4 SuperSport (3), C4 Ripped SuperSport (2) and C4 Alphabomb Sport, none of them named pre-workout, so a name search misses them. The tub is certified; the brand is not.
What the labels say, where we could read them
Cellucor’s C4 Sport page states 200 mg of caffeine per serving, names CarnoSyn beta-alanine without a dose, and carries the NSF Certified for Sport wording on the same page. 1st Phorm’s Megawatt page prices the tub at $47.99, or $44.99 on subscription, and the researcher’s read of its warning text put caffeine at 150 mg per serving. Megawatt’s page text, in the passages we read, did not itself state NSF certification; that claim rests on NSF’s listing.
Everything else is unread: Klean’s site refuses a plain fetch, Thorne’s page gave us navigation and no panel, and we did not open the rest, so no citrulline, creatine or beta-alanine dose appears here.
Pros and cons of shopping from this list
Verdict
If you compete under anti-doping rules, buy from the table, match the flavour to the row, then read the brand’s own label before deciding whether the certified tub is a good one. For how NSF’s screen compares with Informed Sport and BSCG, our certifier comparison covers the substance counts we did not re-read, and the CELSIUS post explains why so much of the aisle goes without a mark.
Questions people ask about NSF certified pre-workouts
Is C4 pre workout NSF Certified for Sport?
C4 Sport is. NSF’s database lists Cellucor C4 Sport in Blue Raspberry, Fruit Punch and Watermelon under the C4 heading, and Cellucor’s own C4 Sport page states NSF Certified for Sport beside 200 mg of caffeine. Check the row: the mark sits on C4 Sport’s listed flavours, not on the C4 name.
What does NSF Certified for Sport mean?
It is a private third-party certification mark, not a regulator approval. NSF tests listed products against a screen of banned substances, checks that the label matches the contents, and lists each certified product by flavour on nsfsport.com. It says nothing about whether the doses inside are large enough to work, and it covers only the SKUs and lots listed.
Is Ghost pre workout NSF certified?
Not on the rows we read. Our name search of NSF’s database on 15 September 2026 returned no row containing pre-workout wording under the Ghost name, and the researcher’s earlier pass of the same page found only GHOST Energy cans. That is a scoped absence from one database on one date, not a verdict on Ghost’s testing.
As ever: none of this has been evaluated by the FDA, nothing here is intended to diagnose, treat, cure or prevent disease, this is not medical advice, and it is for adults. Follow the serving on the tub and, if you are tested, the lot number too.
