Creatine COA Guide: How to Read a Certificate of Analysis

What Is a Certificate of Analysis?

A COA reports analytical information for a specific ingredient batch or lot. It is not a universal quality guarantee.

Raw-Material Testing vs Finished-Product Testing

A COA for a creatine raw material documents that ingredient batch; it should not automatically be described as finished-product testing unless the document actually applies to the finished supplement.

The Referenced Pürest Creatine™ Documentation

Nutribota’s quality education references Pürest Creatine™ High Purity Creatine Monohydrate batch HPCM2026032301, manufactured March 23, 2026.

The raw-material COA lists a dry-basis assay specification of at least 99.5% with a reported result of 100.2%, and a purity specification of at least 99.99% with a conforming result. A separate third-party analytical section for the same referenced raw-material batch reports 99.999% creatine purity.

The 99.999% result is a third-party analytical result for the referenced raw material, not a separate finished-stick-pack purity result. See Quality & Transparency for the full evidence boundary.

Where Nutribota Fits

Nutribota’s flagship format is 5g single-serve Creatine Monohydrate Stick Packs, 60 sticks per bag, unflavored, made with licensed Pürest Creatine™.

See the current flagship product page for current product facts and inventory-based purchase availability. The Creatine collection remains the connected category and education hub.

Final Takeaway

A COA is most useful when it is read as a batch-specific analytical document. Identify what material was tested, what specification applied, and what the reported results actually support.
