Certificates of Analysis – Independent Third-Party COA Verification

Maple Research Labs provides independent third-party Certificates of Analysis (COA) from an independent third-party testing laboratory. Each COA states the compound, the measured HPLC purity and the date tested, and is published here in full. Most certificates are HPLC-UV. Certificates marked HPLC-MS/MS were measured by liquid chromatography with tandem mass spectrometry, which also confirms identity against a reference standard.

This page serves as a centralized index of all current COA documentation across our product catalog. Researchers, institutions, and procurement departments can use this page to verify the testing status and purity data for any compound before placing an order.

How Our Testing Process Works

Our quality verification process includes the following steps:

1. Sample submission: For a tested batch, a sample is sent to an independent third-party laboratory. The certificate is published here once the laboratory issues its report.
2. HPLC analysis: High-Performance Liquid Chromatography (HPLC) determines the exact purity percentage of the compound.
3. COA generation: The laboratory issues a Certificate of Analysis with the purity result, the batch identifier, the date tested and a report number that the laboratory itself can look up.
4. Public verification: Every certificate in the table below is linked in full, and each one can be checked with the laboratory that issued it. Report numbers beginning DBAV are looked up at testides.com/verify. Report numbers beginning COA are issued by SideChain Analytics and carry a Verify at lab link to the laboratory’s own page for that report, or can be entered at sidechainanalytics.com.
5. Product page linkage: The COA document is linked directly on the corresponding product page as COA verification is completed.

Every compound with a current certificate is listed below with its report number, lot, measured purity and test date, and the certificate itself is one click away. Compounds without a current certificate are listed too and marked Awaiting certificate; current availability for every compound is shown on its product page. Use the search box to find a compound, CAS number, lot or report number.

Understanding HPLC Purity Results

High-Performance Liquid Chromatography (HPLC) is the gold standard for peptide purity analysis. The purity percentage indicates the proportion of the target compound relative to total detected substances in the sample. Research-grade peptides are generally specified at 98% purity or higher. Maple Research Labs publishes the measured HPLC value for each tested batch in the table above rather than a single blanket figure, so researchers can confirm the exact purity of the compound they intend to use.

The HPLC method separates individual components of a sample based on their interaction with a stationary phase and mobile phase. Each component produces a distinct peak on the chromatogram, and the relative area of the target compound peak determines the purity percentage.

Why Independent Third-Party Testing Matters

In-house testing creates an inherent conflict of interest: the company manufacturing the product is also the one certifying its quality. Independent third-party testing eliminates this conflict entirely. The laboratory has no financial relationship with Maple Research Labs beyond the testing fee. Every certificate is published here in full, so the result can be read directly rather than taken on the supplier’s word.

What a Certificate of Analysis Establishes, and What It Does Not

A certificate is strong evidence about one thing: the sampled material from one batch, on the date tested, by the method stated. Reading it correctly means knowing the edges of that evidence.

• HPLC purity is chromatographic purity. The figure is the area of the main peak as a percentage of all integrated peaks detected at the stated wavelength (214 nm on most certificates here). It reports UV-absorbing, chromatographically resolved components. It is not an absolute assay of how many milligrams of peptide are in a vial, and it does not account for water content, residual counter-ions such as trifluoroacetate, salts, or components that do not absorb at that wavelength or that co-elute with the main peak.
• Identity is only established where the certificate says so. HPLC-UV alone shows retention behaviour, not identity. Certificates marked HPLC-MS/MS compare the measured mass with the theoretical mass of the compound, which supports identity. Mass alone does not resolve stereochemistry or confirm sequence unless the report includes that data.
• Measured content applies to the sampled units. Where a certificate reports measured content against the label claim, that is the quantity found in the vial or vials the laboratory received. Other vials from the same batch were not individually tested.
• Scope is one lot, one sample, one date. Results describe the material as it reached the laboratory. They do not describe handling, storage or reconstitution after the material leaves us, and they do not carry over to other lots of the same compound.
• Not tested unless stated on the certificate: sterility, bacterial endotoxin, bioburden, heavy metals, residual solvents, water content and biological activity. A purity result is not a sterility result, and no certificate on this page establishes suitability or safety for any use. All materials are supplied for in-vitro research only.
• Laboratory verification confirms the document, not your vial. Looking a report number up at the laboratory confirms that the laboratory issued that report with those values. It does not re-test the material in your hands.

Frequently Asked Questions

How do I verify a COA from Maple Research Labs?

Each COA carries a report number issued by the testing laboratory. For report numbers beginning DBAV, open testides.com/verify and enter the report number to see the laboratory’s own record. For report numbers beginning COA, use the Verify at lab link beside the certificate in the table above, scan the QR code printed on the certificate, or enter the report number at sidechainanalytics.com. The laboratory confirms the certificate is authentic and serves the original PDF from its own site.

What happens if a product does not have a current COA?

We are actively expanding COA coverage across our full catalog. Products with current third-party verification are clearly marked on their product pages. Check the COA status table above for the latest verification status of each compound.

How often are COAs updated?

Certificates are batch-specific. When a new batch of a compound is tested, the new certificate replaces the previous one here and on the product page, and the lot number on the material matches the lot number on the report. Compounds marked Awaiting certificate have not yet had a report issued for the current batch.

Can I request the full COA document for my order?

Yes. Contact [email protected] with your order number and we will provide the batch-specific COA documentation for each compound in your order that has completed independent verification.

A Certificate of Analysis documents the chromatographic purity, and where stated the identity, of a tested batch. It does not establish sterility, endotoxin content, or suitability or safety for any use.
