Certificate of Analysis
Independent third-party laboratory verification for every active research material we distribute.
View COA LibraryVerified by independent labs
Grey Axis Research provides Certificates of Analysis (COAs) for active research materials to support laboratory verification and quality transparency. All materials are designated Research Use Only (RUO) and are not intended for human or animal consumption.
The COA registry is a compiled reference of analytical data including internal (1st party), contracted (2nd party), and independent laboratory (3rd party) testing. Data is provided for research documentation purposes only and should be independently reviewed and validated by the purchasing laboratory prior to experimental application.
Product Testing & Verification
Mass / Content
Quantitative determination of material present per vial based on batch-specific analytical measurement. Reported values may represent individual vial analysis or averaged analytical results derived from multiple tested units.
Purity / Composition
Analytical assessment of sample composition and relative chemical homogeneity as determined through applicable chromatographic and spectrometric methodologies. When available, corresponding batch-specific COAs and issuing laboratory documentation are referenced on the product page.
Sterility / Verification
For select materials, sterility screening or microbiological testing may be included within the associated batch documentation when applicable. Availability of sterility-related data varies by product and laboratory scope.

All materials are designated Research Use Only (RUO) and are not intended for human or animal use. Grey Axis Research does not perform laboratory testing in-house. Any analytical documentation provided is issued by external laboratories and/or independent testing entities. Grey Axis Research makes no warranties regarding the accuracy, completeness, or interpretation of third-party results. Documentation is provided for research recordkeeping and should be reviewed and validated by the purchasing laboratory prior to use.
How to Read a Certificate of Analysis
A Certificate of Analysis, commonly called a COA, provides analytical information about a submitted material sample. Depending on the laboratory, the document may instead be titled a test report or summary report.
These documents can identify the sample tested, the associated batch or lot, the testing party, the analysis date, and the reported results. Because report formats and available analyses vary, each document should be evaluated according to the information it actually contains.

Confirm the Product and Batch Information
Begin by reviewing the identifying information near the top of the report. Depending on the document, this may include:
- Product or sample name
- Labeled material amount
- Batch or lot number
- Client or submitting party
- Manufacturer, when identified
- Sample description
- Testing and analysis dates
- Report or task number
The product and lot information on the report should correspond with the material being evaluated. Results associated with one submitted batch should not automatically be applied to another batch.
If the manufacturer or batch is listed as unknown, the report should not be interpreted as establishing information that the laboratory did not document.
Identify the Laboratory and Verification Information
The report should identify the laboratory or analytical service that performed the testing. Some reports also include a QR code, task number, or unique key that can be checked through the laboratory’s verification system.
Verification can help confirm that a report appears in the laboratory’s records. It does not add tests, findings, or conclusions beyond those stated in the report.
Researchers should refer to the report itself to identify the party that conducted the analysis.
Review the Tests Performed
Analytical reports do not necessarily include the same tests. The document should be reviewed to determine which analyses were performed rather than assuming that every report includes identity, purity, quantity, or microbial testing.
Testing may include methods such as HPLC, LC-MS, UV/Vis analysis, quantitative assay, pH measurement, or microbial-count testing, depending on the material and laboratory.
Purity Analysis
A purity result should be interpreted according to the method and calculation stated in the report. An HPLC area-percent result describes the target peak’s share of the integrated chromatographic signal; it does not necessarily represent the peptide’s percentage by mass. Purity should not be treated as interchangeable with material identity, quantity, or sterility.
If the report does not identify the analytical method, the reader should not assume that the result was produced using HPLC or another particular technique.
Identity or Molecular-Mass Analysis
Identity-related testing evaluates whether measured characteristics correspond with the expected material. Methods such as LC-MS may provide molecular-mass information, but an identity claim should only be connected to LC-MS when that method is documented in the applicable report.
Quantitative Assay or Material Amount
A quantitative result reports the amount or concentration measured in the submitted sample using the stated method. This result may differ from the amount printed on the product label.
For a blended material, the report should be reviewed to determine whether the result represents the complete blend or separately measured components.
Microbial Counts
Total aerobic microbial count and total yeast and mold count tests evaluate microorganisms detected under the conditions stated in the report. These results should not be described as sterility testing unless the report specifically documents a validated sterility analysis.
Understand Specifications and “Pass” Results
Some reports provide an acceptance specification alongside each result. A result may be marked “Pass” when it meets the criterion shown on the document.
Other reports provide numerical findings without displaying an acceptance range or pass/fail determination. In that situation, the numerical result should not be presented as a passing result unless the applicable specification is documented elsewhere.
A pass designation applies only to the test, sample, and acceptance criteria identified in that report.
Consider What the Report Does Not Establish
A COA or test report documents the analyses reported for a particular submitted sample. Unless specifically supported by the document, it does not necessarily establish:
- Testing of every possible characteristic
- Results for a different product or batch
- The identity or quantity of every component in a blend
- The use of an analytical method not named in the report
- Sterility when only microbial counts were measured
- Safety, therapeutic effectiveness, or suitability for human use
The complete report should be evaluated rather than relying exclusively on a purity percentage or individual result.
