TypePeptide
SequenceLong-acting amylin receptor agonist
Typical doseTitrated; up to ~2.4 mg weekly in trials
FrequencyOnce weekly
RouteSubcutaneous injection
Half-lifeLong — once-weekly dosing.

Overview

Cagrilintide mimics amylin, a hormone that works alongside insulin to control appetite and slow digestion. It is investigational for weight management and has shown strong results combined with a GLP-1 agonist.

How it’s thought to work

  • Activates amylin and calcitonin receptors to increase fullness and slow gastric emptying.
  • Complements GLP-1 agonists via a separate appetite pathway.

Researched uses

  • Weight management (investigational)
  • Combination therapy with GLP-1 agonists

Commonly cited protocol

Typical doseTitrated; up to ~2.4 mg weekly in trials
FrequencyOnce weekly
RouteSubcutaneous injection
NotesTrial dosing; not an approved regimen.

Reconstitution

Often a 5 mg vial. 5 mg with 2 mL water = 2.5 mg/mL, so 300 mcg = 12 units on a U-100 syringe.

Cagrilintide dosage calculator

The calculator below is pre-filled with Cagrilintide’s commonly cited vial size and dose. Adjust the vial amount, bacteriostatic water, or dose to match your own vial — it will show the exact insulin-syringe units to draw, the concentration, and how many doses the vial holds.

📋 In plain English

Add 2 mL of bacteriostatic water to your 5 mg vial. That gives you about 16 doses of 300 mcg. For each dose, draw 12 units into a 100-unit insulin syringe.

Cautions

  • Not approved — still investigational.
  • GI side effects similar to other weight-loss agents.
  • Medical supervision essential.
