Most incretin research compounds are engineered from GLP-1 itself. Mazdutide starts from oxyntomodulin, a gut hormone that already binds both the GLP-1 and glucagon receptors, then modifies it for stability and a longer half-life. That pairs an intake pathway with an expenditure pathway — the same logic behind Retatrutide's glucagon arm, without the GIP component.

Every 10mg vial is tested to ≥98% purity by RP-HPLC, sealed, lyophilised and batch numbered. A batch-specific Certificate of Analysis is published against each lot and downloadable from the COA page.

Mazdutide is water-soluble. Reconstitute the lyophilised vial with bacteriostatic water added slowly down the side of the vial, swirl gently rather than shaking, then store at 2–8°C and use within roughly 28 days. Use our free calculator to work out target concentrations.
