Certificates of Analysis
Tested by an outside lab. Published for you.
Each Vici lot goes to an independent analytical laboratory before it is listed. The signed certificate for every batch lives on this page. Look yours up by compound or lot number.
Certificate Library
One card per lot. Open the certificate, or go straight to the compound.
Lot numbers are printed on the vial label (for example RT20-2601-01). Paste one here to pull up that exact certificate.

What the full panel checks.
Each certificate reports these six results. What they mean:
Peptide purity01
RP-HPLC, UV 214 nmReverse-phase HPLC separates the sample and reports how much of the peptide material is the target compound. The lab specification is 98% or higher; our published lots run above 99%.
Net peptide content02
HPLC quantitationHPLC quantitation reports the milligrams of peptide actually present in the vial, listed next to the labeled amount on each card.
Identity & molecular weight03
LC-MSLiquid chromatography paired with mass spectrometry confirms the vial contains the named compound, and the measured mass is checked against the reference value.
Microbial sterility04
Growth screenAn accelerated growth screen checks the lyophilized material for bacterial contamination.
Endotoxin05
LAL, <0.5 EU/mLBacterial endotoxin is measured against a 0.5 EU/mL limit; the pass/fail result appears on every certificate.
Heavy metals06
Pb · Cd · As · HgLead, cadmium, arsenic and mercury are screened individually and reported one by one.

Three routes to the same document.
01Search this page
Enter the compound name or the lot number from your label in the library above.
02Check the product page
Each compound's page lists its current and earlier certificates beneath the description.
03Confirm with the laboratory
Every report is signed and carries the laboratory's own report number. Email us with that number and we will confirm the report directly with the lab.
Common questions.
What does a certificate of analysis tell me?
It is a signed laboratory report tied to one specific lot. It states what the compound is, how pure it is and how much is in the vial. The full panel adds molecular weight, microbial sterility, endotoxin and a four-metal heavy-metals screen.
Where is the certificate for the vial I bought?
Search the lot number from your label in the library above, or open the compound's product page, where the certificate section sits beneath the description. If a lot isn't published yet, email [email protected] with your order number.
How should I read the numbers?
Match the lot number to your vial first. Purity is the share of peptide material that is the named compound. Net content is the measured milligrams, shown beside the labeled amount. Identity confirms the compound by LC-MS or FTIR. Full-panel certificates also report sterility, endotoxin and heavy metals.
Who runs the tests?
Independent analytical laboratories with no ownership or financial ties to Vici Peptides. Each report carries the lab's own report number and analyst signatures.
When does a new certificate get added?
Each production lot is tested before it goes on sale. When a new lot arrives, its certificate becomes the "Latest" entry for that compound and the earlier one remains in the library marked archived.
