Same creatine, so pay for less
Both hold creatine monohydrate and nothing else, and a scoop of either gives 5 g. Creatine monohydrate is the form with the most research behind it (Kreider 2017). We found no study comparing these two brands, so at the same dose we don’t expect one to work better. Thorne’s tub holds 90 scoops; the BulkSupplements bag holds 100.
Testing: both are on the same two NSF lists
- NSF Certified for Sport lists both. It tests for substances banned in sport and checks that the label is right, Thorne’s two listings hold 77 lot reports; BulkSupplements’ two hold 10. If you are drug-tested, match your tub’s lot number on the listing. BulkSupplements listing · Thorne listing.
- NSF/ANSI 173 lists both too (BulkSupplements · Thorne). That standard checks the label and sets limits for contaminants.
