Concentration matrix for Tirzepatide
Each cell = concentration for that vial mass and diluent volume, with mcg per U-100 unit and nmol/mL (from MW 4813). Concentration = vial mg ÷ water mL.

|---|---|---|---|---|
| 5 mg | 5.00 mg/mL 50.0 mcg/unit · 1039 nmol/mL |
2.50 mg/mL 25.0 mcg/unit · 519 nmol/mL |
1.67 mg/mL 16.7 mcg/unit · 346 nmol/mL |
1.00 mg/mL 10.0 mcg/unit · 208 nmol/mL |
| 10 mg | 10.00 mg/mL 100.0 mcg/unit · 2078 nmol/mL |
5.00 mg/mL 50.0 mcg/unit · 1039 nmol/mL |
3.33 mg/mL 33.3 mcg/unit · 693 nmol/mL |
2.00 mg/mL 20.0 mcg/unit · 416 nmol/mL |
| 15 mg | 15.00 mg/mL 150.0 mcg/unit · 3117 nmol/mL |

Handling & notes
Amphiphilic like other fatty-acylated incretin peptides; water-soluble but surface-active, so it foams if agitated. Slight opalescence can appear at higher concentrations and clears on standing.
