Product Details
Survodutide Peptide (BI 456906) — Research Grade Peptide, ≥98% Purity (HPLC)
Dual GCGR/GLP-1R agonist. Oxyntomodulin analog. Lyophilized powder. Lot-specific COA included.
Survodutide, also known as BI 456906, is an investigational once-weekly dual agonist at the glucagon receptor (GCGR) and the glucagon-like peptide-1 receptor (GLP-1R). The compound is designed to replicate the actions of oxyntomodulin, an endogenous GCGR/GLP-1R dual agonist that influences body weight and liver health. Its proposed mechanism combines reduced food intake through GLP-1 receptor agonism with glucagon receptor-mediated effects on energy expenditure and hepatic metabolism. Preclinical studies indicate that Survodutide peptide acts through circumventricular organs in the brain and activates neuronal regions associated with appetite regulation, including GLP-1R–expressing satiety nuclei.
The dual mechanism distinguishes Survodutide peptide from selective GLP-1 receptor agonists. GLP-1R activation mediates insulin secretion, appetite suppression, and gastric emptying, while GCGR activation increases energy expenditure and hepatic fatty acid oxidation. In Phase 2 trials, participants assigned to the 4.8-mg dose achieved a mean body-weight reduction of up to 18.7% at 46 weeks, compared with 2.3% with placebo.
Supplied as a sterile-filtered, lyophilized powder for in vitro and preclinical research applications. Each lot is independently verified for purity and identity and ships with a Certificate of Analysis. Survodutide peptide

Note: Survodutide peptide is supplied in both free base and salt forms. Verify the exact form, molecular weight, and purity against the Certificate of Analysis supplied with your lot. Independent testing of commercial Survodutide products has reported purity ranging from 99.87% to 99.95% in some samples, with fill deviations up to +7% relative to stated amounts.
Research applications
Survodutide is used in laboratory settings to investigate:
-
Dual incretin receptor signaling — simultaneous activation of GCGR and GLP-1R, and downstream cAMP accumulation via adenylyl cyclase in transfected cell lines
-
Hepatic lipid metabolism and MASH/MASLD research — suppression of lipid uptake, de novo lipogenesis, and lipid droplet formation, with most adults with obesity and serious fatty liver disease reaching at least a 30% reduction in liver fat over 48 weeks in Phase 3 trials
-
Energy expenditure and adipose tissue research — GCGR-mediated lipolysis and thermogenesis in diet-induced obese (DIO) mouse models
-
Circumventricular organ signaling — activation of neuronal regions associated with appetite regulation and satiety nuclei
-
Glycemic control research — HbA1c reductions up to 1.21% from baseline in adults with obesity and type 2 diabetes in Phase 3 trials
-
Analytical method development — LC-MS/MS quantification and reference standard preparation for dual agonist peptide analysis
Handling and storage
Reconstitute under aseptic conditions using sterile water or an appropriate aqueous buffer. Survodutide peptide is soluble in water. Aliquot immediately after reconstitution to avoid repeated freeze-thaw cycles. Lyophilized powder is stable for up to 2 years at −20 °C under sealed, desiccated, light-protected conditions. Reconstituted solutions should be stored at 2–8 °C and used within 14–21 days. Do not freeze reconstituted solution.
