Researchers sourcing tirzepatide for preclinical studies, referred to in the research catalog as GLP-2 TZ, need a supplier that understands the analytical requirements for a dual incretin receptor agonist with lipidation chemistry similar to the GLP-1 SM class but with additional sequence complexity to engage both the GLP-1 and GIP receptors. This guide covers the supplier evaluation criteria and shows how Midwest Peptide meets those criteria for research grade GLP-2 TZ supply.

Frequently Asked Questions
What is Tirzepatide (GLP-2 TZ) in research contexts?
+
Tirzepatide (GLP-2 TZ) is a synthetic dual GLP-1/GIP receptor agonist with a 39-amino-acid sequence and a fatty-acid modification for extended half-life. It is studied in preclinical research for glucose regulation, food intake, and adipose tissue endpoints.
What sourcing standards apply to tirzepatide research peptides?
+
Verify HPLC purity above 98%, mass spec identity confirming the 39-amino-acid sequence and the C20 diacid fatty acid modification, peptide content quantification, endotoxin testing, and a recent batch-specific COA. Stability data is essential.
Where can research labs source verified tirzepatide?
+
Midwest Peptide supplies research-grade tirzepatide (GLP-2 TZ) with comprehensive COA documentation, HPLC purity verification, mass spec identity, fatty acid modification confirmation, and lot tracking for reproducible dual incretin agonist research.
Is Tirzepatide (GLP-2 TZ) approved for human use?

- GIP Receptor (GIPR)
- The class B G protein-coupled receptor for GIP, expressed in pancreatic islets, adipose tissue, and other peripheral tissues.
- Lipidation
- Covalent attachment of a fatty acid to a peptide to enable albumin binding and extend plasma half-life.
- C20 Diacid
- An eicosanedioic acid (20-carbon dicarboxylic) modification used in tirzepatide for albumin binding and half-life extension.
- Modified Amino Acid
- A non-canonical amino acid residue introduced into a peptide to alter its stability, receptor selectivity, or pharmacokinetics.
