Overview

Tirzepatide is a synthetic 39-amino-acid peptide engineered as a dual agonist of the glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. A C20 fatty diacid moiety attached via a linker to lysine-20 enables albumin binding and an extended half-life. Supplied as a lyophilized powder for in-vitro research.

  • Dual GIP / GLP-1 receptor agonist
  • Acylated with C20 fatty diacid for albumin binding
  • HPLC purity ≥ 99% on every batch
  • Batch-specific Certificate of Analysis included

Manufacturing & characterization

01

Solid-phase synthesis

Produced by Fmoc solid-phase peptide synthesis followed by preparative RP-HPLC purification.

02

Characterized by LC-MS

Identity confirmed by electrospray mass spectrometry against the theoretical monoisotopic mass.

03

Lyophilized for stability

Freeze-dried under vacuum in sealed, nitrogen-flushed vials to preserve integrity in transit.

  • Matches the COA exactly

    Verified purchase

    Ran our own HPLC on arrival and the purity came back within 0.2% of the certificate. Lyophilized cake was intact and reconstituted cleanly.

    M. Okafor · Cell biology core, university lab · Sep 30, 2026 · 5mg vial

  • Good product, slow courier

    Verified purchase

    Material itself is excellent and the batch documentation is thorough. Standard shipping took four days to reach us, which is at the top of the quoted window.

    R. Patel · Biotech start-up · Sep 13, 2026 · 10mg vial

  • Solid reference material

    Used as a reference standard for a receptor binding assay. Behaved as expected. Would appreciate a 1 mg size for method development.

    A. Fernández · Pharmacology department · Aug 22, 2026 · 15mg vial

  • Fine, but packaging could improve

    Verified purchase

    Peptide quality is good. The outer box arrived dented, though the insulated inner container and vials were unharmed.
