5 mg vial
Cagrilintide: a 5 mg vial
What a 5 mg vial of Cagrilintide becomes once it is mixed, and what each dose reported in the sources draws to on a syringe. Every figure is arithmetic on the vial size in the heading — none of it is a recommendation, and the doses are the ones our sources describe rather than ones we picked.
Leading with
5 mg + 2 mL bacteriostatic water = 2.5 mg/mL
Chosen because it puts the reported doses on readable marks of a 1 mL U-100 syringe. Other volumes are perfectly valid — the dilution table further down covers them, and the concentration changes what every dose draws to.
What each reported dose draws to
At 2.5 mg/mL, on a 1 mL U-100 syringe. Every row names the source it came from, and a trial protocol and a community convention are not the same kind of information.
| Goal | Dose | Units | Doses in this vial | Source |
|---|---|---|---|---|
| Phase 2 escalation, single agentOnce weekly, escalating over several weeks · Subcutaneous | 300 mcg – 4.5 mg | from 12 unitstop of the range needs a second vial | 16 | Clinical trial |
| Combination with semaglutide, as studiedOnce weekly · Subcutaneous | 2.4 mg | 96 units | 2 | Clinical trial |
Check every figure against the vial in front of you before drawing. Vials are filled with an overage and labels are not a guarantee. Change any of these numbers in the calculator.
How long a vial lasts
Vials round up, because most of a vial is not a thing you can buy. Only doses with a stated continuous frequency appear here — anything described as a course, a range or “as needed” has no honest weekly rate, so it is left out.
Phase 2 escalation, single agent
Once weekly, escalating over several weeks
One 5 mg vial holds 0–16 doses at this dose, which is 0–16 weeks of use.
| Cycle | Doses | 5 mg vials | Syringes | Bacteriostatic water |
|---|---|---|---|---|
| 8 weeks | 8 | 1–0 | 8 | 2 mL – 0 mL |
| 12 weeks | 12 | 1–0 | 12 | 2 mL – 0 mL |
| 16 weeks | 16 | 1–0 | 16 | 2 mL – 0 mL |
Combination with semaglutide, as studied
Once weekly
One 5 mg vial holds 2 doses at this dose, which is 2 weeks of use.
| Cycle | Doses | 5 mg vials | Syringes | Bacteriostatic water |
|---|---|---|---|---|
| 8 weeks | 8 | 4 | 8 | 8 mL |
| 12 weeks | 12 | 6 | 12 | 12 mL |
| 16 weeks | 16 | 8 | 16 | 16 mL |
Syringes assume one per dose and no wastage. Water assumes each vial is mixed at 2 mL. Neither accounts for a dropped vial, a bent needle or a dose you decide to change, all of which happen.
If you add a different amount of water
The same 5 mg of compound, at four common volumes. More water means a larger, easier-to-measure draw of a weaker solution; less water means the opposite. The amount of compound you inject is identical in every row — only the volume carrying it changes.
| Water added | Concentration | 300 mcg draws to |
|---|---|---|
| 1 mL | 5 mg/mL | 6 units units · 0.06 mL |
| 2 mLshown above | 2.5 mg/mL | 12 units units · 0.12 mL |
| 3 mL | 1.667 mg/mL | 18 units units · 0.18 mL |
| 5 mL | 1 mg/mL | 30 units units · 0.3 mL |
Storage
Before mixing
Refrigerated at 2–8 °C, protected from light.
After mixing
Refrigerated at 2–8 °C. Do not freeze once mixed.
