Nutricost vs BulkSupplements Creatine (2026): Which to Buy
By Erin Rose Updated October 9, 2026 Methodology
Buy BulkSupplements Creatine Monohydrate. It is the same 5 g of creatine monohydrate as Nutricost, with nothing added, for the same price on Amazon ($0.21 a serving against $0.21). And it is on NSF Certified for Sport, a testing list you can look up. Nutricost is on no public list.

Is it the same creatine?
Yes. Both hold micronized creatine monohydrate and nothing else, 5 g a serving, 100 servings in 500 g (a bag for BulkSupplements, a tub for Nutricost). Creatine monohydrate is the form with the most research behind it (Kreider 2017). No study compares these two brands, so at the same dose we don’t expect one to work better. What differs is testing.
| Per serving | BulkSupplements | Nutricost |
|---|---|---|
| Serving | 5 g (about 2 tsp) | 1 scoop (5 g) |
| Creatine | 5 g | 5 g |
| Form | Creatine monohydrate, micronized | Creatine monohydrate, micronized |
| Other ingredients | None | None |
| Servings | 100 (500 g bag) | 100 (500 g tub) |
| Testing list | NSF Certified for Sport (5 named lots) | None found |
| Brand’s testing claim | “Third-party tested” | “Third party tested” |
| Per 5 g on Amazon | $0.21 | $0.21 |
Testing: only BulkSupplements is on a public list
- BulkSupplements: NSF Certified for Sport. NSF checks that the label matches what is in the pack and screens for more than 280 substances banned in sport. Its listing (1676955) covers the 500 g and 1 kg packs and names 5 certified lots (read September 28, 2026). Match the lot number on your bag to the listing.
- Nutricost: the brand’s own claim. The label says “Third party tested,” and Nutricost’s site says an independent, accredited lab checks the label. It does not name the lab or post results. We found Nutricost on none of the five testing lists we searched on October 5, 2026.

Listing 1676955
Testing matters most if you get drug-tested for sport or work. For everyone else, it means an outside group checks the product where anyone can look it up. It does not make the creatine work better.
How we checked this
We searched each program’s own list for both brands: BulkSupplements on September 28, 2026 (NSF lists) and September 22, 2026 (Informed and USP); Nutricost on all five on October 5, 2026.
| Program | BulkSupplements | Nutricost |
|---|---|---|
| NSF Certified for Sport | Listed (listing 1676955, 5 lots) | Not listed |
| NSF/ANSI 173 | Not listed | Not listed |
| Informed Choice | Not listed | Not listed |
| Informed Sport | Not listed | Not listed |
| USP Verified | Not listed | Not listed |
Nutricost’s searches on two of the lists, October 5, 2026: Informed Sport, “No results were found” and NSF/ANSI 173, “No Matching Products Found”.
Price: the same, or close
On Amazon (October 9, 2026), BulkSupplements’ 500 g bag is $20.97 and Nutricost’s 500 g tub is $21.50. Both hold 100 servings of 5 g: $0.21 and $0.21 a serving. Since the price is about the same, the testing list decides it.
| Pack | Price | Servings | Per 5 g |
|---|---|---|---|
| BulkSupplements, 500 g bag | $20.97 | 100 | $0.21 |
| Nutricost, 500 g tub | $21.50 | 100 | $0.21 |
Prices move. To check a pack you see somewhere else, divide its price by its servings.
