What Is It?

Survodutide

GLP-1 / glucagon dual agonist in clinical study.

Bacteriostatic Water

Sterile water containing a bacteriostatic preservative, commonly used when preparing multi-use research vials.

How To Mix Survodutide

1
Clean

Use alcohol swabs to clean the tops of both vials.

2
Draw BAC Water

Draw the selected amount of bacteriostatic water.

3
Inject Slowly

Add the liquid slowly down the side of the vial.

4
Swirl Gently

Do not shake. Swirl gently until dissolved.

5
Store Properly

Store as directed and protect from heat and light.

Best Practices & Common Mistakes

Best Practices

  • Use sterile technique.
  • Protect from light and heat.
  • Store refrigerated when appropriate.
  • Use clean syringe-unit math before measuring.

Common Mistakes

  • Confusing milligrams with milliliters.
  • Choosing an option with awkward decimal units.
  • Using too little liquid for very small measurements.
  • Shaking the vial aggressively.

Survodutide Storage & Handling

Lyophilized Powder: −20°C (−4°F) for long-term storage (up to 24 months). Refrigeration 2–8°C (36–46°F) for short-term use (up to ~3 months). Original sealed vial in the freezer is safest.
Reconstituted Solution: 2–8°C (36–46°F), use within ~7–14 days. Keep sealed, avoid light, and do not repeat freeze-thaw cycles.

Frequently Asked Questions

Survodutide is acylated with a C18 diacid, which binds to plasma albumin to extend the half-life to around 5.5 days—designed for once-weekly dosing. Using the calculator's default daily schedule would lead to dangerous accumulation. Always calculate your doses on a per-week basis, not per day.
Don't just trust the calculator's numbers. Survodutide is soluble in PBS at around 10 mg/mL, but at higher concentrations, the C18 fatty acid chain can cause aggregation. If your formula requires a very concentrated solution (e.g., >10 mg/mL in water), the powder may not dissolve fully. Use more BAC water to stay within a safe solubility range.
No. The lyophilized powder is stable for at least a year at -20°C, but once reconstituted, most suppliers recommend aliquoting and freezing to avoid multiple freeze/thaw cycles. Don't rely on the calculator's generic "4°C" temperature assumption for long-term peptide storage.
Titration takes weeks, not days, to improve gastrointestinal tolerability. The calculator will show you the correct weekly dose, but you must separately track the titration schedule, increasing the dose every 2-4 weeks. The calculator itself doesn’t manage the start low, go slow escalation plan.
The molecular weight listed in references (4231.63 g/mol) refers to the free base peptide. However, research vials are often the acetate or TFA salt form. The calculator won't know the difference; check your Certificate of Analysis (CoA) for the exact peptide content.
Practical takeaway: If your real goal is weight or metabolic health, the most useful next step is discussing approved treatment options with a clinician rather than relying on an unapproved compound.
