Example Cagrilintide Titration Schedule
| Weeks | Dose | Note |
|---|---|---|
| Weeks 1–4 | 0.25 mg | Phase 3 start |
| Weeks 5–8 | 0.5 mg | Step +0.25 |
| Weeks 9–12 | 1.0 mg | Step +0.5 |
| Weeks 13–16 | 1.7 mg | Step +0.7 |
| Weeks 17+ | 2.4 mg | Phase 3 target |
| (Max studied) | 4.5 mg | Phase 2 top dose |
Investigational. Phase 2 dose levels were 0.3 / 0.6 / 1.2 / 2.4 / 4.5 mg — the 0.6 → 1.2 → 1.8 mg ladder does not exist in any trial; 4.5 mg adds minimal benefit over 2.4 mg.

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 goal involves weight management, metabolic health, recovery, physical performance, cognitive function, appearance, or general well-being, discuss it with a licensed healthcare professional. They can help you evaluate approved, evidence-based options rather than relying on an unapproved or investigational compound. This calculator is intended only for transparent research-reference calculations and does not determine an appropriate amount, recommend use, or replace professional medical guidance.
