# What should a research peptide vial label show?

A research peptide vial label should show the compound name, the stated amount (for example 10 mg), a printed lot number that matches the CoA, the storage condition and a research-use-only statement. The lot number is the critical field: it is the only link between the vial in your hand and its test results.

## Which fields matter, and why?

| Field | Why it matters |
| --- | --- |
| Compound name | Identity; must match CoA |
| Stated amount (mg) | Basis for concentration calculations |
| Printed lot number | Links vial to CoA and retained samples |
| Storage condition | Protects quality until use |
| Research-use statement | Defines intended use |
| Supplier name | Who to contact about the lot |

## Why is a printed lot number better than a handwritten one?

-   It is applied at the same step for the whole lot, reducing mix-ups.
-   It is legible and permanent (the 'legible' and 'enduring' parts of ALCOA+).
-   It can be matched character for character to the CoA.

## What does ICH Q7 say about labelling?

ICH Q7 requires that labels be controlled, that labelling operations prevent mix-ups, and that labels carry the batch number so each container is traceable to its batch record.

## What should a lab record from the label?

-   Compound, amount and lot number in the lab inventory.
-   A photo of the label for traceability.
-   Date received and storage location.

## How does Sable label vials?

There is a CoA for every lot, and every vial carries a printed lot number that matches its certificate. A CoA is emailed within 2 hours of a request.

## Frequently asked questions

### What is the most important field on a peptide vial label?

The printed lot number, because it links the vial to its CoA.

### Should the stated amount be used for concentration?

It is the starting point; net peptide content on the CoA gives a more exact figure.

### Why print rather than handwrite lot numbers?

Printing is consistent across the lot, legible and permanent, reducing mix-ups.
