Checking starts with the lot number.
Search by compound, then match the lot number printed on your vial to its certificate of analysis. Each report comes from an independent third-party laboratory. Full reports open for signed-in researchers.

Reading a certificate
What the numbers mean
Every certificate on the site follows the same layout, so you can compare lots at a glance.
- COA number and lot — the report ID from the lab and the lot printed on your vial. They should match.
- Purity — the main peak as a percentage of everything the detector saw. Our specification is greater than 99%.
- Net content — measured milligrams versus the label. The result is reported against the labeled amount.
- Endotoxin — EU/mL against the 0.5 EU/mL limit, with the assay’s own controls listed.
- PASS / REVIEW — a result inside specification is marked PASS. Anything outside it is marked REVIEW on the site, never removed.

How a batch is released
From synthesis to a published certificate
Our peptides are third-party lab tested, and each lab report is tied to a lot number. The same number is printed on the vial you receive.
1
Synthesis and lyophilization
Peptides are synthesized and freeze-dried in US facilities, then assigned a lot number that follows the batch through every later step.Lot number printed on every vial
2
Samples go to the independent lab
Finished vials from the lot are sent to BioRegen. The lab receives a sample reference and a security key, so a report can be matched back to the lot it describes.Third-party, not in-house
3
LC-MS: identity, purity, net content
The sample is analysed by LC-MS. The chromatogram and mass spectrum are recorded, purity is calculated, and the amount of peptide is measured against the label.Chromatogram and spectrum kept with the report
4
LAL endotoxin screen
A kinetic chromogenic LAL test is run with spike recovery and suitability controls. Results are reported in EU/mL against a 0.5 EU/mL limit.Separate report, same lot number
5
Certificate published, batch released
Results are attached to the product page: the summary and pass/fail status are public, the full PDFs are available to signed-in researchers. Any result outside specification is shown as REVIEW rather than hidden.Tap any purity badge on the site to read it
Questions
Testing, certificates and what to expect
Anything else? Our team can send the full report for any lot you have received.
Contact usWho runs the tests?
Independent third-party laboratories. Elivena does not issue its own certificates; every report carries the lab’s COA number, analyst and instrument.
How do I find the certificate for the vial I received?
Open the product page and compare the lot number on your vial with the lot on the certificate. Sign in to download the original PDF reports.
What happens when a result is outside specification?
The result is marked REVIEW on the site rather than removed, so the record stays complete. A lot is only described as conforming when every assay on its certificate passes.
Are these products for human use?
No. Every product is supplied strictly for in-vitro laboratory research and is not for human or veterinary use.
Every product page carries its certificate
Lab testing explains each assay and how to read a certificate.
