Our verdicts
Creatine Monohydrate
Bloom Creatine delivers the right 5 g dose of micronized monohydrate and gets good marks from buyers, so it works as well as any basic creatine. The problem is price: you pay premium-brand money without the named third-party certification that premium competitors offer. Buy it if you love the brand; otherwise the same result costs less elsewhere.

Creatine (Signature Spec)
Momentous offers some of the most thoroughly documented creatine on the market, with NSF Certified for Sport status and batch-level test results. It is an excellent choice for tested athletes and documentation-minded buyers, but the price is steep, and shoppers who valued it specifically for Creapure should know the raw material has changed.
