Retatrutide + Cagrilintide Blend Dosage Calculator
Enter how much bacteriostatic water was added and the blend dose — this returns the exact draw on a U-100 insulin syringe and how many mcg of each peptide in the blend that draw delivers.
Retatrutide + Cagrilintide Blend ships as a fixed-ratio blend (Retatrutide 12.5mg + Cagrilintide 2.5mg = 15mg/vial), so one draw delivers all components in that ratio.
| Component | Share of vial | Per this dose |
|---|---|---|
| Retatrutide | 12.5 mg (83%) | 1,000 mcg (1.00 mg) |
| Cagrilintide | 2.5 mg (17%) | 200 mcg (0.20 mg) |
U-100 syringe: 100 units = 1 mL. Figures are arithmetic from the vial size, diluent volume and dose entered. Protocol presets report community-reported and published protocols for research context, not a recommendation. Verify against your own vial label.
Documented Retatrutide + Cagrilintide Blend protocols
The presets above come from these commonly reported protocols, reported for research context rather than as a recommendation.
| Protocol | Dose | Frequency | Typical length |
|---|---|---|---|
| Maintenance Stack (12 weeks) | 1.2 mg | 1x/week | 12 weeks |
| Higher Maintenance (12 weeks) | 2.4 mg | 1x/week | 12 weeks |
| Extended Run (24 weeks) | 3.6 mg | 1x/week | 24 weeks |
How the math works
Concentration = total vial mg ÷ bacteriostatic water (mL). Draw volume = blend dose ÷ concentration. On a U-100 syringe, 100 units = 1 mL. Each component scales by its share of the vial, so the ratio is fixed no matter the dose.
