Ghrelin Reconstitution Calculator
Reconstitute a 5 mg vial of Ghrelin with 2 mL of bacteriostatic water for a concentration of 2.50 mg/mL — meaning one unit on a U-100 insulin syringe (0.01 mL) holds 25 mcg. Adjust the inputs below for your own vial and dose.

Ghrelin mg-to-units quick reference
At the default 2.50 mg/mL (5 mg in 2 mL), draw the following units on a U-100 insulin syringe:
| Target dose | Volume | U-100 units |
|---|---|---|
| 250 mcg (0.25 mg) | 0.100 mL | 10.0 units |
| 500 mcg (0.50 mg) | 0.200 mL | 20.0 units |
| 1000 mcg (1.00 mg) | 0.400 mL | 40.0 units |
Frequently Asked Questions
How do I reconstitute Ghrelin?expand_more
Add 2 mL of bacteriostatic water to the 5 mg Ghrelin vial for a concentration of 2.50 mg/mL. Inject the water slowly down the vial wall and swirl gently — do not shake.
How many units is a Ghrelin dose on an insulin syringe?expand_more
At 2.50 mg/mL, one unit on a U-100 syringe (0.01 mL) holds 25 mcg. Divide your target dose in mcg by 25 to get the number of units to draw.
What is the typical Ghrelin research dose?expand_more
Ghrelin is typically dosed at ~25-150 mcg per dose (≈0.3-2 mcg/kg); IV in studies; research only in research protocols. See the full titration schedule on the protocol page.
