The BioLongevity Labs COA Process

Every compound BioLongevity Labs ships carries a lot-matched certificate of analysis issued by an independent testing laboratory.

The certificates themselves are published in full in the COA Library, open to anyone, with no account and no purchase required.

This page explains how that testing works, what each certificate reports, how to read the numbers on your own document, and how to verify it directly with the laboratory that wrote it.

Four steps, and the whole process takes under a minute.

If your lot number does not appear, contact help@biolongevitylabs.com with a photo of the label and the certificate will be sent directly.

The full certificate library lives on its own page. It holds the current record for every lot in distribution, plus the endotoxin reports issued as standalone documents.

Certificates are ordered newest first and filter by product. Older lots stay published rather than being replaced, so the full testing history for each compound remains available.

A peptide certificate of analysis is the analytical record for one production lot. It reports what the material is, how pure it is, how much of it is in the vial, and what it should look like.

Five categories appear across the documents in the library.

Identity, purity, and quantity describe the synthesis itself. Endotoxin describes the handling, filling, and storage steps that follow it.

Both are important when material is going into a controlled protocol, which is why endotoxin results are always published, whether they sit on the certificate itself or in a separate report.

BioLongevity Labs uses more than one independent laboratory, and each one issues its documents in its own house format. The layout, the section names, and the field labels differ between them.

The reported measurements do not. Identity, purity, quantity, & appearance appear on every certificate regardless of which laboratory produced it.

BioLongevity Labs does not test its own material. Samples are sent to independent analytical laboratories, including MDx BioAnalytical Laboratory, Inc. and BioRegen, and the certificates published in the library are the documents those laboratories return.

Three points explain why that separation is worth the added step.

You do not have to take a published copy on faith. Every certificate in the library carries a document number and a route back to the laboratory that issued it.

Certificates carry a certificate of analysis identifier and a QC tracking number. Search the identifier at mdxbiolabs.com under the Certificates of Analysis tab. The QR code printed on the document opens the same record.

Certificates carry a COA number and a security key. Enter both at bioregen.com/verify. The QR code printed on the document opens the same record.

Each certificate also names the person who signed it, with a direct email address at the laboratory, if you would rather ask them.

If a document number does not resolve at the laboratory, email help@biolongevitylabs.com and it will be investigated.

Most questions about certificates come down to a handful of fields.

The product page states the minimum specification the lot has to clear. The certificate states what the lot actually measured, which normally sits above it. A specification of 99% with a measured result of 99.6% means the lot cleared the floor with room to spare.

This is the quantity of compound the laboratory measured in the vial, reported in milligrams against the labeled quantity. Measured content normally sits at or above the label rather than below it, because vials are filled with an allowance for handling and transfer loss.

Some certificates carry a verdict column alongside each result. Conforms means the result meets the specification. Over-conforming means the result sits above the specification rather than failing it, which is most common on quantity. Pass is used on endotoxin, where the result is measured against a ceiling rather than a target.

On the chromatogram, the main peak is the target compound. Its position and area are what the purity figure is calculated from. Small peaks at other positions are related substances counted against that figure.

The mass spectrometry section reports the measured mass. Compare it to the theoretical mass for the sequence. Certificates that print the molecular formula, the theoretical molecular weight, the CAS number, and the PubChem CID let you make that comparison without leaving the document. Salt forms such as acetate will read higher than the free base, which is expected rather than a discrepancy.

Certificates show when the sample reached the laboratory and when the analysis was reported. Those dates belong to the sample, not to the certificate’s publication date, so they are the figures to cite in a methods section.

Lyophilized material stored at negative 20 degrees Celsius holds for three to five years. Reconstituted material is intended for short-term use under sterile conditions.
