Mazdutide

Subcutaneous injection
Written by Peptide Association Editorial TeamMedically reviewed by Ian Justl Ellis, MD, CPTLast reviewed Editorial policy

Overview

Mazdutide is a dual glucagon-like peptide-1 (GLP-1) and glucagon receptor agonist delivered as a synthetic peptide. By co-activating both receptors, it aims to combine the glucose-lowering and weight-reducing effects of GLP-1 with the energy-expenditure and hepatic fat-reducing actions of glucagon receptor stimulation.

Mechanism of Action

This dual mechanism is hypothesized to provide enhanced metabolic benefits in obesity and metabolic dysfunction-associated steatotic liver disease.

Research Summary & Key Findings

Phase 2 studies in obesity have shown significant weight reduction and improvements in liver fat content compared to placebo. Data presented at international obesity and liver meetings in 2022 and 2023 support further development in metabolic indications. Phase 3 trials are in progress to confirm these findings in larger populations.

Clinical Status

In Clinical Trials

Mazdutide is currently undergoing clinical trials. It is not yet FDA-approved and is available only through clinical research settings or investigational protocols.

No lawful pathway today

Mazdutide is not FDA-approved and does not currently have a lawful prescription or compounding pathway in the United States, so there is nothing for us to sell you here and no consultation to book. That can change: eight peptides moved back to a lawful pathway in February 2026.
