Reconstitution calculator
Cagrilintide reconstitution calculator
A 5 mg Cagrilintide vial with 2 ml of bacteriostatic water holds 2,500 mcg per ml - so 1,200 mcg, as pure arithmetic, is a 48-unit draw on a U-100 insulin syringe. Change any of those numbers and the answer moves; the calculator below does the moving for you, and further down is the thing the vendor calculators never mention: where Cagrilintide actually stands with regulators right now.

What you are working with
Cagrilintide has no approved standalone form anywhere - Novo Nordisk's amylin analog exists in clinical trials and in the CagriSema combination (with semaglutide) now under FDA review, neither of which is sold as a vial. What gray-market sellers offer is lyophilized powder, commonly labeled 5 mg or 10 mg, produced outside any quality system - an FDA warning letter names cagrilintide among unapproved drugs sold online, some under coded product names.
The reference table below shows the concentration each common vial-and-water combination produces. These are arithmetic facts about Cagrilintide vial sizes, not guidance about amounts - the same table exists for BPC-157 and TB-500 (Thymosin Beta-4), with different numbers.
| Vial | + 1 ml water | + 2 ml water |
|---|---|---|
| 5 mg | 5,000 mcg/ml | 2,500 mcg/ml |
| 10 mg | 10,000 mcg/ml | 5,000 mcg/ml |
While you are here - where Cagrilintide stands
RestrictedCagrilintide is an investigational drug - Novo Nordisk's long-acting amylin analog - with no approved form anywhere in the world. It is furthest along as half of CagriSema, a fixed-dose weekly combination with semaglutide: Novo Nordisk submitted a New Drug Application to the FDA on December 18, 2025 on the strength of the Phase 3 REDEFINE trials, and the agency is expected to review the application during 2026. Until that decision lands there is no legal commercial product containing cagrilintide, and compounding is not an option either: cagrilintide is not a component of any approved drug and is not an eligible bulk substance, so the FDA states plainly that it cannot be used in compounding.
Cagrilintide math, asked and answered
- How much bacteriostatic water do you add to a 5 mg Cagrilintide vial?
- Any amount - water sets the concentration, not the contents. With 2 ml, a 5 mg vial gives 2,500 mcg/ml; with 1 ml it gives 5,000 mcg/ml. More water means the same dose is a larger, easier-to-read draw on the syringe. There is no single correct volume, which is why this page calculates instead of prescribing.
- How many insulin-syringe units is 1,200 mcg of Cagrilintide?
- It depends entirely on how the vial was reconstituted. As arithmetic: in a 5 mg vial with 2 ml of water (2,500 mcg/ml), 1,200 mcg is 48 units on a U-100 syringe. With 1 ml of water instead, the same 1,200 mcg is 24 units. The calculator above does this for your actual numbers.
- Is Cagrilintide legal right now?
- Restricted - Cagrilintide is an investigational drug - Novo Nordisk's long-acting amylin analog - with no approved form anywhere in the world.
