Is BulkSupplements creatine NSF certified?
Partly, 4 of the 5 sizes we track, not all of them. NSF lists a specific set of package sizes against each certificate, and BulkSupplements sells sizes that those listings do not name. Since the certificate is what NSF actually stands behind, we treat a package it does not name as unconfirmed rather than certified.
| Package | Named by an NSF listing? | Certificate |
|---|---|---|
| 100 g | Yes | 1796571 |
| 250 g | Yes | 1796571 |
| 500 g | Yes | 1676955 |
| 1 kg | Yes | 1676955 |
| 5 kg | Not named | 1676955 |
Why there is more than one answer
BulkSupplements holds 2 separate Certified for Sport listings for this product (1796571, 1676955). NSF records the brand under more than one spelling, so a search on the brand name alone can return one listing and miss another, which is exactly what happened to us, and it is why the table above is built from both.
The 5 kg package is not named by either listing. BulkSupplements' customer service told us in August 2026 that all sizes from 100 g to 5 kg are certified; the certifier's own listings do not say that, and where a seller and a certifier disagree about the certifier's scope we go with the certifier. We have asked NSF directly and will publish the answer.
What each product page shows
Every BulkSupplements product we track, across all categories: Is BulkSupplements third party tested?
Where to buy: the creatine monohydrate shortlist
The pick is the cheapest certified product, at the exact package sold where the certifier names packages, with no adverse finding on record, a price its retailer let us read recently, and no more than a year’s supply at the label’s serving; per delivered dose where the retailer publishes a delivery rate. Where none does, it is the cheapest such product before delivery, and it says how far the order is from free delivery. It is the same pick the category page shows. Any answer shown beside it is the cheapest under a different rule and says so on its own line; answers that cost more than the pick fold under one line until you ask for them.
How these lines are chosen
Among 61 products and 74 retailer listings we track; Amazon and Walmart are not included. A month is thirty doses of the size in the heading, priced the same way as the per-dose figure beside it. “Delivery known” ranks only products whose retailer publishes a delivery rate; a cheaper product with an unpublished rate is on its own line, or in the full list below.

What this rests on: prices we last recorded at the retailer named on each product page, which go stale, and each page says when it was checked; the products we track, not every product sold, and Amazon and Walmart are not among the stores; listings and labels read at the source, each linked from the page.
