Tirzepatide: Sourcing, Purity, and Verification Standards
How SpartaLabs sources, tests, and verifies tirzepatide for research applications. Educational reference.

GLP-1 / GIP dual receptor agonist. Lyophilized.
In Stock
Tirzepatide is a synthetic 39-amino-acid peptide that acts as a dual agonist of the GLP-1 and GIP receptors, modified with a C20 fatty-diacid moiety for extended albumin-binding stability in research preparations.
It is a reference dual-incretin compound in preclinical metabolic-research literature.
Lyophilized under inert atmosphere. Reconstitute with sterile bacteriostatic water; store reconstituted samples refrigerated. For laboratory and research use only. Not for human or veterinary use.
Every batch of Tirzepatide is independently tested by a third-party laboratory. Certificates of Analysis include HPLC purity testing, mass spectrometry confirmation, and sterility verification.
