What should a peptide label include?

A peptide label is small, but it should carry a specific set of information. What is on it, and what is missing, tells you a lot about the supplier.

4 min read Reviewed for accuracy Research Use Only
The short answer

A proper peptide label should include the compound name, the amount in milligrams, a batch or lot number, a clear research-use-only statement, and storage guidance. The batch number should tie to a certificate of analysis.

What belongs on the label

What missing information tells you

If a label lacks a batch number, an amount, or an RUO statement, you lose the ability to verify what you have. Complete, honest labeling is a basic sign of a supplier that takes quality seriously.

Key takeaways

  • A label should list compound, amount in mg, batch number, RUO, and storage.
  • The batch number ties the vial to its certificate of analysis.
  • The mg amount is total peptide, not a dose.
  • Missing label information is a warning sign.
