At a glance
A long-acting amylin analogue investigated in appetite and weight research.
This profile separates the compound’s scientific background from specification-specific preparation and source schedules. Begin with the research findings and limitations, then select the formulation you want to examine.
How it works
Potential benefits & side effects
Interpret each outcome in the context of the study population, formulation and evidence type. Research findings do not establish a personal treatment outcome.
Potential benefits & research findings
Weight and metabolic outcomes are central to the cited trials. Findings from cagrilintide alone and from a combination regimen should be read separately.[4][5][12]
Read the original publications to see the measured endpoints, comparator, duration and uncertainty. Mechanistic plausibility and a favorable experimental result are different from demonstrated clinical benefit.
Side effects & evidence limitations
Interpret the reported adverse effects together with the study population, route and observation period. Small or short studies can miss uncommon and delayed harms. Evidence from a related compound does not establish the safety of Cagrilintide.
Source-reported adverse effects and cautions

Standard / Gradual Approach (3 mL = ~3.33 mg/mL)
| Week/Phase | Weekly Dose (mg) | Units (per injection) | Volume (mL) |
|---|---|---|---|
| Weeks 1–2 | 0.6 mg | 18 units | 0.18 mL |
| Weeks 3–4 | 1.2 mg | 36 units | 0.36 mL |
| Weeks 5–6 | 2.4 mg | 72 units | 0.72 mL |
| Weeks 7–16 (Maintenance) | 4.5 mg | 135 units | 1.35 mL |
Route: Subcutaneous injection. Frequency: Once weekly on a consistent day. Note: The maintenance dose of 4.5 mg requires 135 units (1.35 mL), which exceeds a standard U‑100 insulin syringe capacity. Use a 3 mL syringe with an appropriate subcutaneous needle (e.g., 25–27G, ½–⅝ inch) for doses above 1.0 mL. For titration doses (≤72 units), a U‑100 insulin syringe provides excellent accuracy.
Additional schedule context & duration
Concise summary of the once‑weekly regimen.
- Goal: Support satiety, reduce food intake, and promote weight management over time[2][4].
- Schedule: Weekly subcutaneous injections for 12–16 weeks (or longer as appropriate).
- Dose Range: 0.6–4.5 mg weekly with gradual titration every 2 weeks.
- Reconstitution: 3.0 mL per 10 mg vial (~3.33 mg/mL) for practical volume measurements.
- Storage: Lyophilized frozen; reconstituted refrigerated; avoid repeated freeze–thaw cycles.
Suggested weekly titration approach based on clinical trial designs[1][6].
- Start: 0.6 mg weekly for the first 2 weeks to assess tolerability.
- Escalate: Double the dose every 2 weeks (0.6 → 1.2 → 2.4 → 4.5 mg) as tolerated.
- Target: 4.5 mg weekly by Weeks 7–8; maintain at this dose.
- Frequency: Once per week (subcutaneous) on the same day each week.
- Timing: Any consistent time; rotate injection sites.
Preparation
Reconstitution Steps
- Draw 3.0 mL bacteriostatic water with a sterile syringe.
- Inject slowly down the vial wall; avoid foaming or vigorous agitation.
- Gently swirl or roll until fully dissolved (do not shake).
- Label with date and concentration; refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.
- Use within 30 days of reconstitution; discard if cloudy or particulate matter appears.
Storage Instructions
Proper storage preserves peptide integrity and potency.
- Lyophilized: Store at −20 °C (−4 °F) in dry, dark conditions; minimize moisture exposure.
- Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F); use within 30 days and avoid freeze–thaw cycles.
- Allow vials to reach room temperature before opening to reduce condensation uptake.
Injection Technique
General subcutaneous guidance from clinical best‑practice resources[13][14].
- Clean the vial stopper and skin with alcohol; allow to air dry completely.
- Pinch a skinfold; insert the needle at 45–90° into subcutaneous tissue[13].
- Do not aspirate for subcutaneous injections; inject slowly and steadily.
- Hold for 5–10 seconds before withdrawing the needle to ensure complete delivery.
- Rotate sites systematically (abdomen, thighs, upper arms) each week to avoid lipohypertrophy[14].
Materials & quantity planning
Source materials checklist · 10 mg
Plan based on an 8–16 week weekly protocol with gradual titration.
-
Peptide Vials (Cagrilintide, 10 mg each):
- 8 weeks ≈ 2 vials (17.4 mg total needed)
- 12 weeks ≈ 4 vials (35.4 mg total needed)
- 16 weeks ≈ 6 vials (53.4 mg total needed)
-
Syringes:
- Weeks 1–6 (doses ≤72 units): U‑100 insulin syringes work well
- Weeks 7+ (doses >100 units): 3 mL syringes with 25–27G subcutaneous needles
- Per week: 1 syringe
- 8 weeks: 8 syringes
- 12 weeks: 12 syringes
- 16 weeks: 16 syringes
-
Bacteriostatic Water (10 mL bottles): Use 3.0 mL per vial for reconstitution.
- 8 weeks (2 vials): 6 mL → 1 × 10 mL bottle
- 12 weeks (4 vials): 12 mL → 2 × 10 mL bottles
- 16 weeks (6 vials): 18 mL → 2 × 10 mL bottles
-
Alcohol Swabs: One for the vial stopper + one for the injection site each week.
- Per week: 2 swabs
- 8 weeks: 16 swabs
- 12 weeks: 24 swabs
- 16 weeks: 32 swabs → recommend 1 × 100‑count box
Calculate a phased quantity
Enter each finite phase from the schedule you are studying. Open-ended phases need an explicit duration. Calculation uses 10 mg per vial and 3 mL per vial.
Complete each phase to calculate totals.
Quantity estimates exclude preparation losses and expiry. Follow the formulation’s handling and disposal requirements.
