Cagrilintide Dosage & Reconstitution Guide
Research and educational use only — not medical advice, and not for human consumption. The figures below are summarized from public sources, product labeling, and community reports, and are not a prescription or a substitute for a qualified clinician.
Reconstitution
Cagrilintide ships as a freeze-dried (lyophilized) powder that has to be mixed with bacteriostatic water before use. Draw 1 mL of bacteriostatic water into a syringe and add it to a 5 mg vial, letting the stream run down the inside wall of the glass rather than blasting the powder directly. Swirl gently — never shake — until the solution is clear, then keep it refrigerated.
Worked example. 1 mL into a 5 mg vial gives a concentration of 5 mg/mL (5000 mcg/mL). A 4.5 mg dose then works out to 0.9 mL = 90 units on a U-100 insulin syringe. Scale the water volume up or down to make your target dose land on an easy-to-read mark (1 unit = 0.01 mL).
- Wipe both vial stoppers (peptide and bacteriostatic water) with an alcohol swab and let them dry.
- Draw 1 mL of bacteriostatic water into a syringe.
- Inject it slowly against the inside wall of the peptide vial.
- Swirl gently until fully dissolved; do not shake.
- Label the vial with the contents, concentration, and date, and store it in the refrigerator.
Dosing schedule
| Phase | Dose | Volume | Insulin units (U-100) | Notes |
|---|---|---|---|---|
| Weeks 1–4 | 0.3 mg | 0.06 mL | 6 units | weekly — starter step |
| Weeks 5–8 | 0.6 mg | 0.12 mL | 12 units | weekly |
| Weeks 9–12 | 1.2 mg | 0.24 mL | 24 units | weekly |
| Weeks 13–16 | 2.4 mg | 0.48 mL | 48 units | weekly |
| Week 17+ | 4.5 mg | 0.9 mL | 90 units | weekly — trial target/maintenance |
Timing & cycling
Same day each week, any time; rotate abdomen/thigh sites.
Cycle length. Trials ran continuous weekly dosing with monthly escalation steps.
Storage & handling
Keep the lyophilized (unmixed) vial refrigerated at 2–8 °C (36–46 °F) in a dry, dark place — it tolerates short periods at room temperature during shipping. Once reconstituted, store it at 2–8 °C, never frozen, and use it within about 2–4 weeks (sooner if the solution turns cloudy or discolored). Swab the stopper before every draw and use a fresh needle each time.
Supplies you'll need
- Cagrilintide vials — about 8 for an 8-week run at the upper dose
- Bacteriostatic water — 1 mL per vial (a 10–30 mL multi-dose bottle covers several vials)
- U-100 insulin syringes (0.3–0.5 mL / 30–50 unit barrels are easiest to read) — roughly 8 for 8 weeks, plus spares
- Alcohol swabs — one per injection and one per vial draw
- Sharps container for safe needle disposal
Key points
- An amylin analog — in trials it is most powerful combined with semaglutide (CagriSema), but that is a clinical-trial protocol, not a home recipe.
- Escalate monthly at most; slower is fine.
What to monitor
Weight trend and GI tolerance; nausea is dose-gated the same way as with GLP-1s.
Legal & prescription status
No legal prescription exists. It is an unapproved research chemical, sold only for laboratory research and labelled 'not for human consumption.' It is not FDA-approved for any human use.
