COA Guide
How to read a peptide COA with more confidence.
A certificate of analysis should help you confirm that the document matches the product and lot details connected to your order. This guide keeps that review simple, practical, and close to the rest of the Vigor verification path.
Start Here
Four things to check first on a peptide COA.
You do not need a complicated lab workflow to review a certificate. Most shoppers just need to confirm the document belongs to the right product, the right lot, and the right order context before they move on.
Lot or batch details
Check that the lot information shown on the item or order materials lines up with the certificate you are reviewing.
Document timing
Review the certificate date so you understand when the documentation was issued as part of the record trail.
Support path
If something does not match, pause and use the support path before placing a repeat order or relying on the document.
Quick Checklist
Use this review flow when a certificate lands in front of you.
The goal is not to overcomplicate the process. The goal is to keep the certificate tied to the exact product and order details you are trying to verify.
- Open the product page or order confirmation so you have the product name in front of you.
- Match the product name on the COA to the item you ordered.
- Compare any lot or batch details shown on the item or order materials to the certificate.
- Keep the COA with the order confirmation so support can help faster if a question comes up later.
- If a key detail feels off, stop and contact support before assuming the record is complete.
Why This Matters
Clear records reduce guesswork.
When a certificate, order record, and product page all point to the same item details, it becomes much easier to review the purchase path with confidence.

Common Questions
What a COA review can and cannot do.

A COA should stay with the order.

A mismatch is a support moment.
