Leuprolide Reconstitution Calculator
Reconstitute a 15 mg vial of Leuprolide with 3 mL of bacteriostatic water for a concentration of 5.00 mg/mL — meaning one unit on a U-100 insulin syringe (0.01 mL) holds 50 mcg. Adjust the inputs below for your own vial and dose.

Leuprolide mg-to-units quick reference
At the default 5.00 mg/mL (15 mg in 3 mL), draw the following units on a U-100 insulin syringe:
| Target dose | Volume | U-100 units |
|---|---|---|
| 250 mcg (0.25 mg) | 0.050 mL | 5.0 units |
| 500 mcg (0.50 mg) | 0.100 mL | 10.0 units |
| 1000 mcg (1.00 mg) | 0.200 mL | 20.0 units |
Frequently Asked Questions
How do I reconstitute Leuprolide?expand_more
Add 3 mL of bacteriostatic water to the 15 mg Leuprolide vial for a concentration of 5.00 mg/mL. Inject the water slowly down the vial wall and swirl gently — do not shake.
How many units is a Leuprolide dose on an insulin syringe?expand_more
At 5.00 mg/mL, one unit on a U-100 syringe (0.01 mL) holds 50 mcg. Divide your target dose in mcg by 50 to get the number of units to draw.
What is the typical Leuprolide research dose?expand_more
Leuprolide is typically dosed at 1 mg (1000 mcg)/day SC; depot 7.5 mg monthly to 45 mg every 6 months in research protocols. See the full titration schedule on the protocol page.
