To convert a cagrilintide amount to U-100 units, first find your concentration by dividing the vial’s milligrams by the milliliters of bacteriostatic water you added — for example, a 5 mg vial reconstituted in 1 mL gives 5 mg/mL. Then units = your amount in mg / concentration x 100, because a U-100 syringe reads 100 units per milliliter. Cagrilintide is investigational with no established standalone dose, so you supply your own value and the tool never presets one. This is arithmetic only, not medical advice — verify every number with a licensed clinician.

Reconstitution / draw volume / syringe units / supply-chain
Arithmetic checks out. Confirm clinically, against the label, and against the actual vial before any use.
Independent check - dose mg / concentration mg/mL = volume. U-100 units = mL x 100.
Phase 2 monotherapy trial tested 0.3, 0.6, 1.2, 2.4 and 4.5 mg weekly
Study range only; do not substitute CagriSema combination-study doses.
Investigational amylin analogue; no approved standalone product concentration or label.

Same-syringe co-draw. Reconstitute each peptide in its own vial, then draw them into one syringe.
- Reconstitute each peptide in its own vial — never add water to multiple peptides in one vial.
- Only co-draw peptides with the same diluent (e.g. both bacteriostatic water) and compatible pH.
- Draw and inject fresh — do not pre-mix and store; mixture stability is not established.
- No blended stack is clinically validated. Verify each component and confirm with a clinician.
Cagrilintide dose to syringe units: reference chart
| Vial + water | Concentration | Units per 1 mg | 0.3 mg | 0.6 mg | 1.2 mg | 2.4 mg | 4.5 mg |
|---|---|---|---|---|---|---|---|
| 5 mg + 1 mL | 5 mg/mL | 20 | 6 | 12 | 24 | 48 | 90 |
| 5 mg + 2 mL | 2.5 mg/mL | 40 | 12 | 24 | 48 | 96 | 180 |
| 5 mg + 3 mL | 1.67 mg/mL | 60 | 18 | 36 | 72 | 144 | 270 |
| 10 mg + 1 mL | 10 mg/mL | 10 | 3 | 6 | 12 | 24 | 45 |
| 10 mg + 2 mL | 5 mg/mL | 20 | 6 | 12 | 24 | 48 | 90 |
| 10 mg + 3 mL | 3.33 mg/mL | 30 | 9 | 18 | 36 | 72 | 135 |
Concentration = vial strength divided by the bacteriostatic water added. On a U-100 syringe 100 units = 1 mL, so units = (dose divided by concentration) x 100. Values are syringe units, not milligrams. Amber values exceed 100 units, which is more than one standard 1 mL U-100 syringe holds, so that combination needs a more concentrated solution. Columns are the doses studied in the published trial - they describe what has been studied or labeled, not what anyone should take, and this page gives no dosing advice. Multiply the units-per-1-mg figure by your own dose in milligrams to convert any amount. For vial sizes or doses not shown here, use the general mg to units converter.

Frequently asked questions
What is cagrilintide’s current regulatory status?
Cagrilintide is an investigational long-acting amylin analogue that has been studied in clinical trials but has no standalone regulatory approval and is not marketed on its own. Because nothing about it is cleared for self-administration, this calculator ships without any preset dose and simply converts a milligram figure you supply into syringe units.
Which cagrilintide vial strengths does this tool calculate from?
Cagrilintide is commonly supplied as 5 mg or 10 mg lyophilized vials. Enter whichever total you actually have, plus the volume of bacteriostatic water you reconstitute it with, and the tool returns the U-100 units to draw. To decide how much water to add for a given concentration, use the /tools/bac-water-calculator.
What weekly amounts were tested in the cagrilintide monotherapy trial?
A Phase 2 dose-finding monotherapy study evaluated once-weekly subcutaneous doses of 0.3, 0.6, 1.2, 2.4, and 4.5 mg — a 0.3 to 4.5 mg range (PMID 34798060). These are trial figures shown for context only and are not a dosing recommendation for you.
Do CagriSema combination doses transfer to standalone cagrilintide?
No. CagriSema pairs cagrilintide with semaglutide in a single formulation, and the doses from those combination studies are a frequent source of confusion. They are not interchangeable with single-agent cagrilintide amounts, so don’t enter CagriSema figures on this page.
Can this page tell me how much cagrilintide to inject?
No. It does arithmetic only — turning a milligram amount into U-100 syringe units — and is not medical advice. Since cagrilintide is investigational, there is no established or approved self-use dose to rely on; confirm any decision with a qualified clinician.
