Creatine COA Guide: How to Read a Certificate of Analysis
PublishedA Certificate of Analysis, or COA, can help consumers understand how an identified raw-material or finished-product batch was evaluated. Identify what material was tested, which batch the document covers, what specification applied, and what the reported result means.

What Is a Certificate of Analysis?
A COA reports analytical information for an identified material or product batch. It may cover a raw ingredient or a finished supplement; read the sample name and lot number to establish which. It is not a universal quality guarantee or a substitute for the full test report.
How to Read a Creatine COA Step by Step
- Confirm the material name. The document should identify the ingredient or product that was submitted for testing.
- Match the lot or batch number. Results apply to the identified sample, not automatically to every lot sold under the same brand.
- Separate specifications from results. A specification is the acceptance limit; the result is what the laboratory reported for that sample.
- Check the units. Percent, mg/kg, ppm and CFU/g describe different measurements and should not be compared as if they were interchangeable.
- Read the method and reporting language. “Pass,” “conforms,” “not detected” and a numerical result do not all mean the same thing.
- Identify who issued the document. A supplier COA, manufacturer COA and independent laboratory report have different roles.
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.
Finished-Product Report Example: Batch VB26097500
The provided SGS report image GZF26-0057291-01, dated September 24, 2026, identifies the submitted sample as Nutribota Creatine Monohydrate Stick Packs, batch VB26097500. This is separate from the raw-material batch and purity result above.
Its creatine monohydrate result is 5.04 g/serving, not a purity percentage or a guarantee of the amount in every stick. Nine result rows are marked “Pass”; the mould, yeast and creatine monohydrate rows show a dash in the comment column. “ND” is retained as printed and must not be treated as zero.

| Field | What the provided image shows | How to interpret it |
|---|---|---|
| Sample and batch | Nutribota Creatine Monohydrate Stick Packs; VB26097500 | Match the named submitted sample and batch. Do not substitute the raw-material batch number. |
| Creatine monohydrate result | 5.04 g/serving | An amount per serving for the tested sample, not a purity percentage or a guarantee for every stick. |
| Comment column | Nine rows show “Pass”; mould, yeast and creatine monohydrate show a dash | Keep the printed comments distinct. A dash must not be rewritten as a “Pass” statement. |
| ND and units | Some entries use ND; metal results use mg/day and their LOQ entries use mg/kg | ND does not mean zero. Read each unit and limit together; different units cannot be compared as if identical. |
| Document scope | Provided report image GZF26-0057291-01, September 24, 2026 | A batch-specific image with the limitations described below; it is not product or sport certification. |
Compare the sample name, batch number, result unit, limit and comment for each test. Metal results are reported with mg/day units, while their LOQ entries use mg/kg.

Read the Footnotes Before Drawing a Conclusion
The referenced NNB supplier COA contains two scope notes: items marked with an asterisk are periodically analyzed, and results marked with a triangle come from the third-party analytical report. Do not read these notes as evidence that every listed test was newly performed on every production batch.
The third-party report CHG-50381416-0 also lists detection and quantitation limits, a test-location code, and a sample identifier. These details are part of the result, not optional fine print. If a decision depends on a result near a reporting limit or on the testing frequency, ask the document issuer for clarification.

Common Sections on a Creatine COA
| Section | What to verify | Why it matters |
|---|---|---|
| Identity | The sample is identified as the stated creatine material | Purity numbers are not useful if identity is unclear |
| Assay or purity | Specification, result, basis and method | Shows how much of the measured material was reported |
| Related impurities | Named compounds, limits and reported values | Provides more context than a purity headline alone |
| Heavy metals | Which metals, units and limits were evaluated | Confirms the scope of the reported screen |
| Microbiology | Organisms or counts tested and their limits | Clarifies which microbiological checks were included |
Questions to Ask Before Relying on a COA
- Does the batch number match the material or finished product being discussed?
- Is the document complete and legible?
- Are the test date, method, units and acceptance limits shown?
- Does the report cover raw material or the finished packaged supplement?
- Are marketing statements narrower than, and consistent with, the actual report?
How to Choose a Quality Creatine Product
Use documentation as part of a broader product check rather than relying on one front-label phrase.
- Identify the creatine form. The label should clearly state what type of creatine is present.
- Confirm the amount per serving. Do not confuse total powder weight with grams of creatine.
- Read the complete ingredient list. Check flavors, sweeteners, blends and other active ingredients.
- Look for lot-specific documentation. Match the material, batch, date, method and reported result.
- Separate raw material from finished product. Each document should be described according to what was actually tested.
- Check directions, warnings and manufacturer information. Quality communication includes more than a purity percentage.

Creatine COA FAQ
Is a raw-material COA the same as a finished-product COA?
No. A raw-material COA applies to the identified ingredient batch. A finished-product COA must identify the packaged product and its applicable batch.
Does “not detected” mean zero?
No. It generally means the result was below the stated method’s detection or reporting limit. Read the method and limit shown on the report.
Can a COA prove that every future batch is identical?
No. A COA is batch-specific. Ongoing quality review requires documentation tied to each relevant lot.
