At a glance
Synthetic peptide that simultaneously activates the GLP-1 and glucagon receptors. Developed by Boehringer Ingelheim and Zealand Pharma; in phase-3 trials for obesity (SYNCHRONIZE) and MASH. No marketing approval yet.

US: Unapproved
No FDA approval. Phase-3 programme SYNCHRONIZE is ongoing; an approval decision is expected no earlier than 2026.
Survodutide is a dual agonist at the GLP-1 and glucagon receptors. The GLP-1 component mediates glucose-dependent insulin secretion, inhibition of glucagon secretion at high blood glucose and modulation of satiety. The glucagon component raises basal energy expenditure via hepatic and brown adipocyte effects. A fatty-acid side chain enables albumin binding and weekly dosing.

What the studies show
Human RCT
Mensch
Le Roux CW. et al. 2024
Weight reduction over 46 weeks documented in a phase-2 obesity trial
What does NOT follow: Phase-2 data; phase-3 programme SYNCHRONIZE is ongoing. Long-term data beyond 1 year pending.
Human RCT
Mensch
Sanyal AJ. et al. 2024
Histological MASH improvement reported in a phase-2 trial over 48 weeks
What does NOT follow: Phase 2 with biopsy endpoints; phase-3 confirmation with clinical endpoints (liver disease progression) pending.
Human RCT
Mensch
Le Roux CW. et al. 2024
Gastrointestinal adverse events (nausea, diarrhoea) were dose-dependently frequent across all phase-2 trials
What does NOT follow: Profile similar to other incretin-based substances; titration phase relevant.
05
Pharmacokinetics
Theoretical concentration curve at a half-life of 168 h. Pure pharmacokinetic model — not a dosing recommendation.
Which routes of administration the available studies describe — neutral reporting, not a usage guide.
Subcutaneous
In all phase-1 and phase-2 trials administered subcutaneously once weekly.
07
Known adverse events from studies
Factual reporting of what studies observed. Not a safety statement for individual use.
Human RCT
Nausea / vomiting
Most frequent events documented in phase 2; often transient during titration.

Human RCT
Transient glucose increase
Consequence of the glucagon component; clinically not significant in the obesity studies, to be monitored carefully in diabetes settings.

Interactions & combinations
Documented interactions and contraindications from studies, prescribing information and guidelines. Where no data exists, this is stated.
Reporting of risks, NOT a combination guide. The absence of an entry does not mean „safe to combine“ but „not sufficiently studied“.
No documented interactions recorded
We have not yet found robustly documented interactions for this peptide. This does NOT mean none exist — the data is limited.

Reconstitution calculator
Pure mg/mL maths — works like a calculator. Not a usage recommendation.
Peptides ship as a dry powder. Once dissolved in a liquid (reconstitution), this calculator answers a single question: how much substance is in one millilitre of solution afterwards?
1Enter the vial's substance amount (printed on the label).
2Enter how much solvent you add.
3Result = concentration in mg per mL.

mg / mL
5 mg in 2 mL gives 2.50 mg/mL — each millilitre contains 2.50 mg of substance.
