Survodutide

Limited human data

Investigational glucagon receptor / GLP-1 receptor dual agonist peptide · Also known as BI 456906, glucagon/GLP-1 dual agonist

Overview

Survodutide is an investigational once-weekly peptide that activates both the glucagon receptor and the GLP-1 receptor; the glucagon component is intended to raise energy expenditure and act directly on the liver, while GLP-1 activity reduces appetite and supports glycemic control. In a published Phase 2 trial in metabolic dysfunction-associated steatohepatitis (MASH), it significantly improved liver histology versus placebo, and a separate Phase 2 obesity trial showed clinically meaningful weight loss. The evidence is encouraging but mid-stage: as of 2026 it is in Phase 3 development (for both MASH and obesity) and is NOT FDA-approved. Developed by Boehringer Ingelheim (with Zealand Pharma). It is a true peptide.

Commonly Reported Uses

These are uses commonly discussed or marketed by users and vendors — not a list of proven or approved benefits, and not a recommendation.

  • Metabolic dysfunction-associated steatohepatitis (MASH) / liver fibrosis (investigational; Phase 2 human data, not FDA-approved)
  • Weight loss / obesity (investigational; Phase 2 human data)
  • Type 2 diabetes glycemic control (investigational; earlier human data)

What to Track

Data points you and your clinician might monitor. For observation only — not a diagnostic protocol.

  • Labs — ALT/AST and other liver enzymes if a clinician is monitoring liver effects
  • Smart scale — weight and body-fat % trend
  • InBody/DEXA — skeletal muscle mass vs. fat mass during weight loss
  • Labs — HbA1c and fasting glucose for glycemic response
  • Subjective — daily nausea, appetite, and GI tolerability check-ins

Safety & legal notes

NOT FDA-approved; investigational and only legitimately available in clinical trials. In the Phase 2 MASH trial, adverse events more frequent than placebo included nausea, diarrhea, and vomiting. As an incretin/glucagon dual-agonist peptide, it is not the same mechanism class as banned growth-factor peptides; GLP-1-class agents are currently monitored (not prohibited) by WADA, but athletes should verify the current List. Long-term human safety is not established. Consult a licensed clinician.
