Use this free calculator to reconstitute Retatrutide for research: enter the milligrams in your vial and the millilitres of bacteriostatic water, and it returns the concentration in mg/mL, the volume to draw for any target, and the U-100 unit equivalent. The reference data and concentration matrix below are specific to Retatrutide and can be checked by hand or cited.

Concentration matrix for Retatrutide
Each cell = concentration for that vial mass and diluent volume, with mcg per U-100 unit and nmol/mL (from MW 4731.33). Concentration = vial mg ÷ water mL.
| Vial ↓ / Water → | 1 mL | 2 mL | 3 mL | 5 mL |
|---|---|---|---|---|
| 5 mg | 5.00 mg/mL 50.0 mcg/unit · 1057 nmol/mL |
2.50 mg/mL 25.0 mcg/unit · 528 nmol/mL |
1.67 mg/mL 16.7 mcg/unit · 352 nmol/mL |
1.00 mg/mL 10.0 mcg/unit · 211 nmol/mL |
| 10 mg | 10.00 mg/mL 100.0 mcg/unit · 2114 nmol/mL |
5.00 mg/mL 50.0 mcg/unit · 1057 nmol/mL |
3.33 mg/mL 33.3 mcg/unit · 705 nmol/mL |
2.00 mg/mL 20.0 mcg/unit · 423 nmol/mL |
| 15 mg | 15.00 mg/mL 150.0 mcg/unit · 3170 nmol/mL |
7.50 mg/mL 75.0 mcg/unit · 1585 nmol/mL |
5.00 mg/mL 50.0 mcg/unit · 1057 nmol/mL |
