M-Series is the Havoc Labs product name for mazdutide research material. Mazdutide, also identified as IBI362 or LY3305677, is a synthetic peptide analogue of oxyntomodulin studied for dual GLP-1 and glucagon receptor activity.
This material is not supplied as a medicine, treatment, supplement or consumer product. It is not for human or veterinary use, consumption or administration, and is not intended to diagnose, treat, cure or prevent any disease.
Compound overview
Research context
Mazdutide is a dual receptor agonist, distinct from GLP-1-only peptides and from compounds combining GLP-1, GIP and glucagon receptor activity. Published research includes controlled studies of metabolic endpoints in defined clinical populations.
Clinical publications describe specific trial formulations, participant groups and monitored conditions. They do not demonstrate equivalence to a Havoc Labs research vial or establish the suitability of this material for human use. Findings and adverse events must be interpreted together; see the Research tab for linked study summaries.
Reference identifiers are not batch verification. Consult the matching analytical documentation for identity, purity and the chemical form supplied. No pharmaceutical formulation, sterility or clinical equivalence is implied by the product name.
Batch documentation
Independent analytical documentation is published where available for specific batches and variations. A result indicator appears only when a published record is available. Match the compound, vial size and batch identifier to the corresponding report before relying on any result.
Supply and laboratory handling
- Supplied as a 10mg vial of lyophilised research material.
- Keep the vial sealed and protected from moisture, heat and direct light.
- Use suitable laboratory controls and independently verify identity and concentration for the intended experimental model.
- Follow batch-specific storage and handling instructions where supplied.
Frequently asked questions
What is M-Series?
The Havoc Labs product name for mazdutide research material. Published literature also uses IBI362 and LY3305677.
Which receptors are studied?
Mazdutide is studied as a dual GLP-1 and glucagon receptor agonist. It is not a GIP/GLP-1/glucagon triple agonist.
Are clinical trials available?
Yes. The Research tab links controlled trials and identifies their populations and limitations. Trial results concern the study materials, not this research batch.
Is this a pharmaceutical product?
No. This page supplies laboratory research material, not the clinical formulations described in published trials.
Are laboratory results available?
A shield appears beside a variation only when a published result is available. Check the COA tab for matching records; no indicator means no product-specific result is currently displayed.
How should the material be stored?
See the Storage Guidelines tab and follow any batch-specific instructions. No human dosing, administration or injection guidance is provided.
