How SpartaLabs sources, tests, and verifies mazdutide for research applications, including synthesis standards, HPLC purity, and third-party COA verification. Educational reference.

GLP-1 / Glucagon dual receptor agonist. Lyophilized.
In Stock
Mazdutide is a synthetic peptide that acts as a dual agonist of the GLP-1 and glucagon receptors, structurally derived from oxyntomodulin.
It has been characterised in preclinical metabolic-research literature as a reference dual-incretin compound.
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 Mazdutide is independently tested by a third-party laboratory. Certificates of Analysis include HPLC purity testing, mass spectrometry confirmation, and sterility verification.
