A Certificate of Analysis is a laboratory document reporting the testing performed on a submitted sample and the results issued by the laboratory.

Our COA library is continuously expanding. Some products are currently undergoing independent third-party testing, and finalized reports will be published once they become available.

The sample may still be under testing, the final report may not yet be issued, or the document may still be awaiting publication.

Testing practices may vary. In some cases, documentation may be available for the individual compounds used in a blend rather than the finished blended product itself.

A reported purity below 99% does not automatically indicate a quality issue. Manufacturers establish their own acceptance specifications based on the specific compound, manufacturing process, validated analytical methods, and internal quality standards. Because these specifications can vary, acceptable purity ranges are not necessarily identical across all manufacturers or products.

Depending on the manufacturer’s established specifications, purity values between 95% and 99% may still meet the applicable acceptance criteria.

At Mile High Peptides LLC, we believe transparency is an important part of quality. We do not try to hide or selectively publish only the highest results. We make available independent third-party Certificates of Analysis as they are received, including results that may vary between products or testing periods.

A Certificate of Analysis should be reviewed as a whole, including identity confirmation, analytical methodology, and any other testing reported by the laboratory—not purity alone.

Every manufacturer establishes its own acceptance specifications based on the specific compound, manufacturing process, validated analytical methods, and internal quality standards. As a result, acceptable purity specifications may differ between manufacturers and products.

For this reason, comparing products solely by a single purity percentage can be misleading. The complete Certificate of Analysis provides a more meaningful assessment than purity alone.

Yes. Testing is an ongoing process, and our COA library is a living resource. As additional products, production runs, or samples are independently tested, reports may be added, updated, or replaced to reflect the most current laboratory documentation available.

A report published today may differ from a report published later as new testing is completed.

Not every concentration of a product is necessarily submitted for separate third-party testing. In some cases, multiple concentrations are prepared from the same active ingredient or source material that has already undergone quality testing.

Depending on the manufacturer and production process, testing may be performed on the active ingredient, representative production samples, or other quality-control samples rather than every individual concentration. Manufacturers establish their own testing protocols and acceptance specifications based on their production and quality-control procedures.

At Mile High Peptides LLC, we publish available third-party Certificates of Analysis as they are received. Because testing is ongoing, additional reports may be added or updated as new products, concentrations, or production runs are independently evaluated.

If a product is not yet listed, it may still be undergoing independent third-party testing. Contact Mile High Peptides LLC support with the exact product name if you have questions about its current testing status.
