A 2 mg Hexarelin vial mixed with 2 ml of bacteriostatic water holds 1 mg/ml. A 100 mcg dose is 0.10 ml — 10 units on a U-100 insulin syringe — and the vial holds 20 doses of that size.
Units on a U-100 insulin syringe (100 units = 1 ml) for Hexarelin doses from 50 mcg to 200 mcg, by how much bacteriostatic water is in a 2 mg vial. The highlighted row is the 100 mcg dose used above.
| Dose | 1 ml water 2 mg/ml | 2 ml water 1 mg/ml | 3 ml water 0.667 mg/ml | Doses per vial |
|---|---|---|---|---|
| 50 mcg | 2.5 u 0.025 ml | 5 u 0.050 ml | 7.5 u 0.075 ml | 40 |
| 100 mcg | 5 u 0.050 ml | 10 u 0.10 ml | 15 u 0.15 ml | 20 |
| 150 mcg | 7.5 u 0.075 ml | 15 u 0.15 ml | 23 u 0.23 ml | 13 |
| 200 mcg | 10 u 0.10 ml | 20 u 0.20 ml | 30 u 0.30 ml | 10 |
A 10-unit draw fits comfortably on a 0.3 ml insulin syringe (30-unit capacity), whose 1-unit (often half-unit) markings are easier to read than the 2-unit ticks on a 1 ml syringe.
Unit math only, not a dosing recommendation. The dose range is what published protocols and trials describe; see the Hexarelin guide for sources.
Hexarelin is a synthetic growth-hormone-releasing peptide that stimulates pituitary GH release. It is the most potent GH-releasing peptide per mcg but shows tachyphylaxis with continuous use.
Half-life: Approximately 70 minutes
Typical dose range: 100 mcg, 1–3x daily
Class: Growth-hormone-releasing peptide (GHRP-6 analog)
Regulatory status: Not FDA approved. Research use only.

Need a different unit or a different question? The peptide dose converter moves a dose between mcg, mg and IU, and the Hexarelin half-life chart shows how concentration accumulates across a dosing cadence. Loading Hexarelin into a reusable 3 ml pen instead of drawing it with a syringe? The peptide pen calculator turns the same vial into mcg per click and clicks to dial. All of them are listed on the free peptide tools page.
Both. This Hexarelin calculator converts vial strength, bacteriostatic-water volume, and target dose into milliliters and insulin-syringe units. It does not recommend a medical dose.
This page is pre-filled with 2 ml of bacteriostatic water for a 2 mg Hexarelin vial because that is a common research ratio. You can adjust the water amount in the full calculator.
10 units on a U-100 insulin syringe, when a 2 mg vial is mixed with 2 ml of bacteriostatic water (1 mg/ml). That is 0.10 ml. With a different amount of water the unit count changes — the dose chart on this page lists 1 ml, 2 ml, 3 ml mixes.
20 doses of 100 mcg. The number of doses depends only on vial strength and dose size — adding more or less water changes the volume of each draw, not how many draws the vial holds.
No. It only performs unit math. Dosing, titration, and whether Hexarelin is appropriate are clinical decisions that should be made with a licensed healthcare professional.
Peptide Protocol remembers your Hexarelin vial, shows the units for every dose, tracks what is left, and rotates injection sites for you.
