Survodutide Dosage Chart

Survodutide is dosed at 600 mcg–6 mg weekly via subcutaneous injection in educational protocols. A 10 mg vial reconstituted with bacteriostatic water yields about 5 mg/mL. This information is for research and educational use only.

• Reconstitute: Add 2.0 mL bacteriostatic water → 5 mg/mL (5000 mcg/mL) concentration.
• Typical weekly range: 0.6–6.0 mg once weekly (gradual titration over 10–12 weeks).
• Easy measuring: At 5 mg/mL, 1 unit = 0.01 mL = 50 mcg on a U‑100 insulin syringe.
• Storage: Lyophilized: freeze at ≤−20 °C (≤−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); protect from light.

Survodutide (BI 456906) is an investigational dual GLP‑1/glucagon receptor agonist under development for obesity and metabolic liver disease. In phase 2 trials, once‑weekly subcutaneous dosing (0.6–4.8 mg) produced dose‑dependent weight loss of 12.5–14.9% versus placebo over 46 weeks. This educational protocol presents a once‑weekly subcutaneous titration approach using a practical dilution for clear insulin‑syringe measurements.

Standard / Gradual Titration (2 mL = 5 mg/mL)

Route & Frequency: Subcutaneous injection once weekly (all clinical trials used weekly dosing).

Week	Weekly Dose (mg)	Weekly Dose (mcg)	Units (mL)
Weeks 1–2	0.6 mg	600 mcg	12 units (0.12 mL)
Weeks 3–4	1.2 mg	1200 mcg	24 units (0.24 mL)
Weeks 5–6	1.8 mg	1800 mcg	36 units (0.36 mL)
Weeks 7–8	2.4 mg	2400 mcg	48 units (0.48 mL)
Weeks 9–10	3.6 mg	3600 mcg	72 units (0.72 mL)
Weeks 11–12	4.8 mg	4800 mcg	96 units (0.96 mL)
Week 13+	6.0 mg	6000 mcg	120 units (1.20 mL)*

*Note: The 6.0 mg maintenance dose (120 units / 1.20 mL) exceeds a standard 100‑unit (1 mL) insulin syringe. Use a 1 mL or 3 mL Luer‑lock syringe with appropriate needle, or administer as two separate injections.

Reconstitution Steps

1. Draw 2.0 mL bacteriostatic water with a sterile syringe.
2. Inject slowly down the vial wall; avoid foaming.
3. Gently swirl/roll until dissolved (do not shake).
4. Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.

Supplies Needed

Plan based on an 8–16 week weekly protocol with gradual titration.

• Peptide Vials (Survodutide, 10 mg each):
  • 8 weeks ≈ 2 vials (~17 mg total)
  • 12 weeks ≈ 4 vials (~39 mg total)
  • 16 weeks ≈ 7 vials (~63 mg total)
• Insulin Syringes (U‑100) or 1 mL Luer‑lock Syringes:
  • Per week: 1 syringe (once weekly)
  • 8 weeks: 8 syringes
  • 12 weeks: 12 syringes
  • 16 weeks: 16 syringes
• Bacteriostatic Water (10 mL bottles): Use 2.0 mL per vial for reconstitution.
  • 8 weeks (2 vials): 4 mL → 1 × 10 mL bottle
  • 12 weeks (4 vials): 8 mL → 1 × 10 mL bottle
  • 16 weeks (7 vials): 14 mL → 2 × 10 mL bottles
• Alcohol Swabs: One for the vial stopper + one for the injection site each week.
  • Per week: 2 swabs
  • 8 weeks: 16 swabs
  • 12 weeks: 24 swabs
  • 16 weeks: 32 swabs → recommend 1 × 100‑count box

Protocol Overview

Concise summary of the once‑weekly regimen.

• Goal: Support metabolic improvement and weight management through dual GLP‑1/glucagon receptor activation.
• Schedule: Weekly subcutaneous injections for 12–16 weeks (or longer as studied in phase 3 trials).
• Dose Range: 0.6–6.0 mg weekly with gradual titration over 10–12 weeks.
• Reconstitution: 2.0 mL per 10 mg vial (5 mg/mL) for accurate unit measurements.
• Storage: Lyophilized frozen; reconstituted refrigerated; protect from light and avoid freeze–thaw.

Dosing Protocol

Suggested weekly titration approach based on clinical trial designs.

• Start: 0.6 mg weekly; increase by 0.6 mg every 2 weeks as tolerated.
• Target: 4.8–6.0 mg weekly by weeks 11–13.
• Frequency: Once per week (subcutaneous).
• Cycle Length: 12–16 weeks minimum; phase 3 trials extend to 48–72 weeks.
• Timing: Same day each week; rotate injection sites.

Storage Instructions

Proper storage preserves peptide quality.

• Lyophilized: Store at ≤−20 °C (≤−4 °F) in dry, dark conditions; minimize moisture exposure.
• Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F); protect from light and avoid repeated freeze–thaw cycles.
• Allow vials to reach room temperature before opening to reduce condensation uptake.

Important Notes

Practical considerations for consistency and safety.

• Use new sterile syringes; dispose in a sharps container.
• Rotate injection sites (abdomen, thighs, upper arms) to reduce local irritation.
• Inject slowly; wait a few seconds before withdrawing the needle.
• Document weekly dose, injection site, and any tolerability observations.
• For doses exceeding 100 units (1.0 mL), consider using a 1 mL Luer‑lock syringe or splitting into two injections.

How This Works

Survodutide is a dual agonist that activates both GLP‑1 and glucagon receptors. The GLP‑1 component enhances satiety and improves glycemic control, while the glucagon component increases energy expenditure and promotes hepatic lipid oxidation. This dual mechanism is hypothesized to provide additive or synergistic effects on body weight and liver fat beyond GLP‑1 agonism alone. In phase 2 trials, survodutide demonstrated substantial weight loss alongside improvements in liver enzyme markers.

Potential Benefits & Side Effects

Observations from clinical literature.

• Dose‑dependent weight loss of 12.5–14.9% (vs placebo) over 46 weeks in phase 2 obesity trials.
• Improvements in liver‑related biomarkers in NAFLD/NASH populations.
• Meta‑analysis confirms consistent weight‑loss efficacy across multiple randomized controlled trials.
• Adverse effects are primarily gastrointestinal: nausea, vomiting, diarrhea, and constipation (most common during dose escalation).
• Gradual titration helps mitigate GI tolerability issues.

Lifestyle Factors

Complementary strategies for best outcomes.

• Pair with a balanced, protein‑forward diet tailored to energy needs; GLP‑1 agonists can reduce appetite significantly.
• Combine resistance training and aerobic activity to preserve lean mass during weight loss.
• Stay well hydrated, especially if experiencing GI side effects.
• Prioritize sleep and stress management to support metabolic health and adherence.

Injection Technique

General subcutaneous guidance from clinical best‑practice resources.

• Clean the vial stopper and skin with alcohol; allow to dry.
• Pinch a skinfold; insert the needle at 45–90° into subcutaneous tissue.
• Do not aspirate for subcutaneous injections; inject slowly and steadily.
• Rotate sites systematically (abdomen, thighs, upper arms) to avoid lipohypertrophy.
