Survodutide

Research Use
Also known as BI 456906

Complete Research Guide

Open each section for the available evidence. Gaps are stated rather than inferred.

Overview

Survodutide is listed as metabolic / glp-1 + glucagon dual agonist.

  • Obesity
  • MASH (investigational)

Regulatory status: Investigational (Boehringer Ingelheim / Zealand, Phase 3).

Structure & Properties

Compound: Survodutide; also known as BI 456906.

Pharmacologic class: Metabolic / GLP-1 + Glucagon Dual Agonist.

Known delivery routes: Subcutaneous.

Sequence, molecular weight, salt form, and excipient details are formulation-specific and are not listed unless verified by a manufacturer or laboratory COA.

How It Works

Dual GLP-1 / glucagon receptor agonist — appetite suppression plus hepatic energy expenditure; strong hepatic-fat reduction.

  • Weight loss
  • MASH/MASLD resolution
  • Improved liver enzymes
Human Research

Evidence grade: Clinical RCT (Limited)

Clinical RCT (Limited). Phase 2 ~19% weight loss; MASH Phase 2 positive.

Laboratory Research

Phase 2 ~19% weight loss; MASH Phase 2 positive

Preclinical findings describe biological plausibility, not proven benefit in people. Animal and laboratory doses do not translate directly to human use.

Processing & Interactions

Timing and exposure

Once weekly.

Potential interactions and combinations to avoid

  • Other incretin-based agonists
  • MTC/MEN2

Absorption, half-life, metabolism, and clearance can vary by formulation and route. Use prescribing information when an approved product exists.

Safety & Precautions

Known or reported risks

  • GI intolerance
  • Heart rate increase
  • Hyperglycemia risk via glucagon arm

Contraindications

  • MTC / MEN-2 (class)
  • Pregnancy
  • Personal or family history of medullary thyroid carcinoma or MEN-2 syndrome
  • History of pancreatitis or unexplained elevated lipase/amylase
  • Gastroparesis, severe GERD, or chronic gastrointestinal motility disorder
  • History of symptomatic gallstones or biliary disease
  • Active eating disorder, malnutrition, or BMI already in the underweight range
  • Type 1 diabetes as monotherapy for glycemic control
  • Planned surgery/anesthesia without pre-procedure fasting adjustment (aspiration risk)
  • Proliferative diabetic retinopathy with rapid glycemic lowering
  • Severe renal impairment with ongoing dehydration or vomiting
  • Bleeding disorders or anticoagulant therapy without physician guidance (injection-site haematoma)
  • Active skin infection, cellulitis, or lipohypertrophy at intended injection sites
  • Inability to maintain sterile technique or safe sharps disposal
  • Not FDA-approved for human therapeutic use — no verified purity, sterility, or potency standards
  • Immunocompromised or transplant patients (unverified sterility and immunogenicity risk)
  • Concurrent participation in drug-tested sport (WADA prohibited or non-cleared substance)
  • Known hypersensitivity or prior reaction to this compound or any excipient/diluent
  • Pregnancy, attempting conception, or breastfeeding unless prescribed and monitored by a physician
  • Children and adolescents with open growth plates (unless under specialist endocrine care)
  • Active or recently treated malignancy without oncology clearance
  • Use without a confirmed diagnosis, baseline labs, and licensed clinical supervision

Unknown long-term toxicity should be assumed where controlled human data are limited. Seek urgent care for a severe or unexpected reaction.

Administration & Studied Formulations

Reference range: 0.6–4.8 mg/week (trial)

Frequency: Weekly

Cycling: Continuous, stepwise titration.

Subcutaneous (SubQ)

Default route for most research and therapeutic peptides — best absorption for reconstituted powder.

31G × 5/16" insulin syringe (U-100). 100 units = 1 mL. Pinch skin at abdomen (2" from navel), outer thigh, or love handle. Insert at 45–90°. Rotate sites daily to prevent lipohypertrophy. Alcohol-swab site, air-dry, inject slow, hold 5 sec.

Dosing information is educational context, not a personal recommendation. Approved products must follow their label and prescriber instructions.

Applications & Related Therapies

Potentially complementary measures

  • Protein-forward diet, resistance training

Clinical use should account for diagnosis, approved alternatives, nutrition, activity, sleep, rehabilitation, current medicines, and appropriate monitoring.

Cases, Considerations & Ethics

Decision framework: establish the clinical goal, confirm evidence quality and legal status, screen contraindications and interactions, compare approved alternatives, define monitoring and stopping criteria, and use shared decision-making with a licensed clinician.

Case evidence: individual reports cannot establish safety or effectiveness and should not outweigh controlled trials.

Ethics: informed consent should distinguish established care from experimental use, disclose uncertainty and cost, avoid overstated claims, and never substitute research products for medically necessary care.

Administration & Technique

Subcutaneous (SubQ)
Default route for most research and therapeutic peptides — best absorption for reconstituted powder.
Device31G × 5/16" insulin syringe (U-100). 100 units = 1 mL.
TechniquePinch skin at abdomen (2" from navel), outer thigh, or love handle. Insert at 45–90°. Rotate sites daily to prevent lipohypertrophy. Alcohol-swab site, air-dry, inject slow, hold 5 sec.

Injection & Application Sites

Front
Back
Subcutaneous (SubQ)
  • Abdomen2 in (5 cm) away from the navel, either side. Fastest, most consistent SubQ absorption.
  • Flank / love handleLateral fat pad above the hip. Good rotation site when the abdomen is tender.
  • Outer thighUpper outer quadrant, a hand-width below the hip. SubQ pinch at 45°.

Diagram is a general illustration, not a medical instruction. Rotate sites every injection, keep 1 in (2.5 cm) between recent sites, and avoid scars, moles, bruises and the navel area.

Cycling

Continuous, stepwise titration.

Timing & Interactions

When to take
Once weekly.
Do not combine with
  • ·Other incretin-based agonists
  • ·MTC/MEN2
Complements
  • ·Protein-forward diet, resistance training

Storage & Reconstitution

Powder (Pre-Reconstitution)
Lyophilized powder: refrigerate 2–8°C for up to 24 months, or freeze at –20°C for extended storage. Keep sealed, desiccated, and protected from light.
After Reconstitution
After reconstitution with bacteriostatic water, refrigerate at 2–8°C and use within 28 days. Discard if cloudy, discolored, or precipitated.
Notes
Do not freeze after reconstitution — freeze/thaw cycles degrade most peptides.
