| Weeks | Cagrilintide | Semaglutide |
|---|---|---|
| Weeks 1–4 | 0.25 mg | 0.25 mg |

Investigational fixed combination (Phase 3 REDEFINE; NDA filed Dec 2025). Both components escalate in parallel in one weekly injection; single-range dosing tables described a different drug.

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.
CagriSema 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 a 2.4 mg maintenance dose. These are the amounts used in clinical research, shown for reference, not a recommendation. Cagrilintide is investigational and not approved; dosing belongs with a licensed clinician.
No — and that's its defining trait. Cagrilintide is a long-acting amylin analogue, a different hormone pathway from GLP-1 drugs like semaglutide. The two are often studied together (the combination is called CagriSema) because they work through complementary mechanisms. For the calculator it makes no difference — the math is the same mg-to-units conversion — but the class is what sets cagrilintide apart.
It's a once-weekly compound, with research protocols escalating to a maintenance dose of around 2.4 mg weekly and some extended schedules going higher (studies note not exceeding ~4.5 mg per dose). Because the half-life is long (~7 days), it isn't dosed daily — a single weekly injection is the studied pattern. These are research figures, not a personal recommendation.
Add BAC water slowly down the side and swirl gently until clear — never shake. A common research 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), or a 10 mg vial with 3 mL (~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 rather than 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.
