Tirzepatide: Chemical Identity and Documentation

Astra Biolabs Research Library · Updated October 4, 2026

Tirzepatide is a peptide-based molecule. This reference explains chemical identifiers and the questions to resolve when reading a laboratory-material listing.

Reference identity

PubChem, maintained by the US National Library of Medicine, records tirzepatide under CID 156588324. Its reference molecular formula is C225H348N48O68. The record represents a defined chemical structure, including its stereochemistry and chemical modifications.

A formula counts atoms in the reference molecule. It does not establish the composition of a supplied vial. When comparing a specification with a database, check the exact structure and chemical form rather than relying on a similar name.

Tirzepatide and the “Tirz” catalog name

The Astra catalog includes listings named Tirzepatide 5mg and Tirz 10mg. “Tirz” is an abbreviated catalog name; it is not a complete analytical identity statement. Confirm the full compound name, chemical form, and lot information on the label and specification.

Amount and concentration are different

Milligrams describe an amount. Milligrams per milliliter describe a concentration and require a stated volume to calculate a total amount. A product title alone may not resolve that distinction. Ask for clarification if the title, description, and label use different units; this reference does not convert an ambiguous listing into a verified specification.

What documentation would support a sample?

  • An exact identity and chemical-form specification.
  • A matching sample or lot identifier.
  • The test method, reported units, and results for that sample.
  • A clear distinction between identity, purity, and quantitative assay.

Astra Biolabs does not currently offer a lab report for these listings. This page does not assert batch-specific purity, identity verification, sterility, or a clinical result.

Read the COA checklist and analytical-methods guide. Materials are listed for laboratory research only, not human or veterinary use. See the research-use policy.
