What Is a Research Peptide Certificate of Analysis?
A Certificate of Analysis (COA) is a quality document issued by an independent third-party laboratory that verifies the testing results for a specific lot of research peptide. A COA documents what the laboratory tested, how it was tested, and what the test results were – providing researchers with external proof of the peptide’s purity and identity before it enters their workflow.
Every Genryse research peptide ships with a lot-specific COA. The COA is generated for that exact batch – not a generic template, not a sample reused across lots. When a new batch of a research peptide is synthesized, it is tested independently, and a new COA is issued.
Compound Name
The full research peptide name and any alternative names referenced in published research literature.
HPLC Purity Result
The purity percentage measured by high-performance liquid chromatography. Must be 99%+ for release.
Molecular Weight (MS)
The molecular weight confirmed by mass spectrometry, verifying the identity of the compound.
CAS Number
The Chemical Abstracts Service registry number for the research compound, confirming the specific compound identity.
Lot Identifier and Test Date
The unique batch identifier and the date of independent laboratory testing for that specific lot.
What Information Appears on a Genryse Research Peptide COA
Every Genryse COA includes the following:
Product name — the research peptide (e.g., BPC-157, GLP-1 Sema, NAD+)
Lot / batch identifier — unique to that production run, traceable through internal records
Date of testing — when the third-party laboratory conducted analysis
HPLC purity result — verified at 99%+ for Genryse research peptides
Mass spectrometry identity confirmation — molecular weight result vs expected value
Testing laboratory — the independent third-party laboratory that conducted the analysis
Storage and handling conditions — recommended for that research peptide
Research-use disclaimer — confirming the research peptide is for laboratory use only
Sample Certificate of Analysis
The following is a representative example of the Certificate of Analysis format Genryse provides for every research peptide lot. Actual COAs are generated from independent laboratory test results specific to each lot.

How to Read a Research Peptide COA
The COA’s most important sections, briefly:
HPLC Purity Result
The HPLC chromatogram shows separation of the research peptide from any synthesis impurities. The percentage purity reported is the proportion of the sample identified as the target peptide. Genryse research peptides are verified at 99%+ – meaning at least 99% of the sample is the target compound.
Mass Spectrometry Result
The mass spectrometry section confirms molecular identity. The reported mass should match the expected molecular weight of the target peptide (within standard analytical tolerances). For example, BPC-157 has an expected molecular weight of 1419.55 g/mol.
Lot / Batch Identifier
Every COA is tied to a specific lot identifier. This identifier matches the label on the research peptide vial – allowing researchers to document the exact lot of research peptide used in their experiments. Strong research practice involves recording the lot identifier in laboratory notebooks or LIMS systems for every reagent.
Request a Current Lot-Specific COA Before Ordering

Research Peptide COA - FAQs
Yes. Every Genryse research peptide ships with a lot-specific Certificate of Analysis. The COA documents the HPLC purity result, mass spectrometry identity confirmation, lot identifier, and testing date for that specific batch.
Yes. Sample COAs for each Genryse research peptide are available on this page. For a current lot-specific COA – covering the exact batch you would receive – contact Genryse directly through the contact page.
All Genryse research peptide testing is conducted by independent third-party laboratories. Independent verification removes any conflict of interest from the testing process and provides researchers with external proof of every quality claim.
99%+ purity means HPLC analysis verified that at least 99% of the research peptide sample is the target compound, with less than 1% impurities. This threshold is documented on every Genryse COA and applies to every research peptide we ship.
A lot-specific COA is a Certificate of Analysis tied to a specific production batch (lot) of research peptide. The lot identifier on the COA matches the label on the research peptide vial – allowing researchers to document the exact lot used in their experiments.
Genryse COAs primarily document HPLC purity and mass spectrometry identity verification. Additional testing such as endotoxin or sterility verification can be requested for specific research peptides – contact Genryse to discuss research-specific testing requirements.
