Every batch of peptides sold by Velyx Research Ltd is accompanied by a Certificate of Analysis. This page publishes all current and historical batch COAs so researchers can verify exactly what they are receiving.
Current status
Opening batch COAs in progress
Velyx is currently in its opening batch phase. Our first stock is being prepared and batch testing is underway. COAs will be published here before any product goes on sale — consistent with our commitment that documentation is always available before purchase.
What is a COA?
Understanding Certificates of Analysis
A Certificate of Analysis is a document issued by a testing laboratory that confirms the identity, purity, and quality of a specific batch of compound. It is the primary document researchers use to verify that what they have received matches the stated specification.
Purity (HPLC)
Confirms the percentage of the active compound relative to total content, measured by High Performance Liquid Chromatography.
Identity confirmation
Confirms the compound is what it claims to be, typically via LC-MS mass spectrometry matching the expected molecular weight.
Batch reference
A unique batch number linking the COA to a specific production run — allowing full traceability from lab to delivery.
Endotoxin testing
Measures bacterial endotoxin levels in the sample — relevant for research applications requiring low endotoxin material.
Our testing process
How we verify every batch
1
Stock received Every new batch arrives at our facility and is logged with its production batch reference before any further steps.
2
Sample drawn for testing A sample vial is drawn from each new batch and prepared for dispatch to our testing laboratory.
3
Laboratory analysis The sample is analysed by HPLC for purity. Results are issued as a formal Certificate of Analysis referencing our batch number.
4
COA published here Once the COA is received and reviewed, it is published in this Quality Centre and linked from the relevant product page — before that batch goes on sale.
5
Products go live Only after the COA is published does the batch become available to purchase. We do not sell product without supporting documentation.
