Our verdicts
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.

Creatine HMB
This is a carefully made, double-certified product with an honest label, and the 5 g of creatine alone guarantees it works. The HMB is dosed at about half of what research typically uses and adds modest benefit at best, which makes the roughly $1.67-per-serving price hard to justify. Tested athletes who want flavored, certified creatine may still find it worthwhile; everyone else can save money with plain monohydrate.
