Hexarelin Dosing Calculator & Reconstitution Guide
A potent growth hormone secretagogue researched for GH release.
Hexarelin is a research peptide. A potent growth hormone secretagogue researched for GH release. To dose it, reconstitute the vial (for example 5 mg in 2 mL of bacteriostatic water for 2.5 mg/mL), then divide your target dose by that concentration to find the units to draw.

What is Hexarelin?
Hexarelin is a synthetic growth hormone secretagogue and one of the more potent ghrelin receptor agonists. Anecdotal community and research reports commonly cite doses around 100 mcg, one to three times per day. Also known as hex.
How many units is each Hexarelin dose?
| Dose | Volume to draw | Units (U-100) |
|---|---|---|
| 100 mcg | 0.04 mL | 4 units |
| 200 mcg | 0.08 mL | 8 units |
Based on a 5 mg vial reconstituted with 2 mL of bacteriostatic water (2.5 mg/mL) and a U-100 insulin syringe. The dose amounts shown are commonly reported by the community and in anecdotal research, not recommendations or medical advice; only the reconstitution math (volume and units) is calculated for you.
How to calculate a Hexarelin dose
- 1
Choose your vial and water
Select your Hexarelin vial size (for example 5 mg) and the volume of bacteriostatic water you will add (for example 2 mL).
- 2
Find the concentration
Divide vial milligrams by water volume. 5 mg in 2 mL gives 2.5 mg/mL.
- 3
Calculate the draw
Divide your target dose by the concentration to get the volume in mL, then multiply by 100 to get units on a U-100 insulin syringe.
- 4
Verify on the syringe
Use the Keel calculator to see the exact draw rendered on a to-scale syringe, with a warning if the dose exceeds the syringe capacity.
Hexarelin dosing FAQ
How do I reconstitute Hexarelin?
A common approach is to add 2 mL of bacteriostatic water to a 5 mg vial, which gives 2.5 mg/mL. Add the water slowly down the vial wall, swirl gently rather than shaking, and let the powder dissolve fully before drawing.
How many units is 100 mcg of Hexarelin?
At 2.5 mg/mL, 100 mcg equals 0.04 mL, which is 4 units on a U-100 insulin syringe.
What Hexarelin doses do people report?
Community and anecdotal reports commonly cite 100 to 200 mcg. These are figures people report, not a recommendation from Keel. Hexarelin is a synthetic growth hormone secretagogue and one of the more potent ghrelin receptor agonists. Anecdotal community and research reports commonly cite doses around 100 mcg, one to three times per day.
Which insulin syringe should I use for Hexarelin?
A U-100 insulin syringe is standard. A 0.3 mL (30-unit) syringe gives the most precise measurement for small draws, while a 0.5 mL or 1 mL syringe is better when the draw exceeds 30 units. Keel warns you when a dose is larger than the syringe you select.
How do I convert Hexarelin micrograms to insulin units?
Divide your dose in micrograms by the concentration in micrograms per millilitre to get the volume in millilitres, then multiply by 100 for units on a U-100 syringe. The Keel calculator does this for you and shows the draw on a to-scale syringe.
How should I store Hexarelin after reconstitution?
Reconstituted peptides are generally kept refrigerated and protected from light, with the unmixed powder stored cooler still. Follow the guidance from your supplier or a licensed healthcare professional for the specific compound.
What if my Hexarelin dose is larger than the syringe holds?
Either use a larger insulin syringe or reconstitute with more bacteriostatic water to lower the concentration, which increases the volume per dose so it fits. Keel flags an over-draw and you can adjust the inputs until the draw fits.
Is Hexarelin dosing the same for everyone?
No. The right draw depends on your vial size, how much bacteriostatic water you add, and your target dose. Always recalculate when any of those change, and consult a licensed healthcare professional.
