What Is It?

Cagrilintide

Long-acting amylin analogue paired with GLP-1 agents.

Bacteriostatic Water

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

How To Mix Cagrilintide

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.

Cagrilintide 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

In studies it's dosed once weekly with slow escalation: 0.6 mg for 4 weeks, then +0.6 mg every 4 weeks — 1.2 → 1.8 mg — typically up to about 2.4 mg. These are research amounts shown for reference, not a recommendation. Cagrilintide is investigational and not approved; dosing belongs with a licensed clinician.
Yes. While one source notes Cagrilintide is soluble in water up to 50 mg/mL, other research No — that's its defining trait. Cagrilintide is a long-acting amylin analogue, a different pathway from GLP-1 drugs like semaglutide. The two are studied together (the combination is called CagriSema) because their mechanisms complement each other. For the calculator it changes nothing — the mg-to-units math is identical — but the drug class is what sets cagrilintide apart.
These blends are studied in research, but the two compounds aren't combined into one formula — each is a separate molecule with its own concentration and schedule. The safe way to use the calculator is one compound at a time: enter cagrilintide to get its units, then enter the other peptide separately. How they're paired in a protocol is a clinical decision, not something a calculator should merge.
Add BAC water slowly down the side of the vial and swirl gently until clear — never shake. A common mix is a 5 mg vial with 2 mL (2.5 mg/mL), so a 2.4 mg dose is ~0.96 mL (96 units); a 10 mg vial with 3 mL gives ~3.33 mg/mL. Moderate concentrations dissolve reliably and make fine dose adjustments easier — the calculator highlights the cleanest unit matches.
About 160 hours — roughly a week. That long half-life is exactly why it's injected once weekly, not daily, and it means levels accumulate over the first several weeks before reaching a steady state. A single-dose calculation describes your first injection; later weekly troughs sit higher than that first amount.
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.
