Hexarelin
Also known as: Examorelin
One of the most potent GH-releasing peptides, though tolerance can build with continued use.
Hexarelin at a glance
| Name | Hexarelin |
|---|---|
| Also known as | Examorelin |
| Category | Growth-hormone axis |
| Type | Peptide |
| Sequence | Hexapeptide GH secretagogue |
| Typical dose | ~100 mcg |
| Frequency | 1–2× daily, often cycled |
| Route | Subcutaneous injection |
| Half-life | Short (~30–70 minutes). |
Overview
Hexarelin is among the strongest GHRPs for acutely raising growth hormone. Its potency comes with a catch — the GH response can diminish (desensitize) with frequent dosing — so it is often used more conservatively or cycled. It has also been studied for effects on the heart.
How it’s thought to work
- Potently activates the GH-secretagogue receptor for a large GH pulse.
- Receptors can desensitize with frequent, high dosing.
Researched uses
- Strong GH release research
- Cardiac and recovery investigation
Commonly cited protocol
| Typical dose | ~100 mcg |
|---|---|
| Frequency | 1–2× daily, often cycled |
| Route | Subcutaneous injection |
| Notes | Lower frequency helps limit desensitization. |
Reconstitution
Often a 5 mg vial. 5 mg with 2 mL water = 2.5 mg/mL, so 100 mcg = 4 units on a U-100 syringe.
Hexarelin dosage calculator
The calculator below is pre-filled with Hexarelin’s commonly cited vial size and dose. Adjust the vial amount, bacteriostatic water, or dose to match your own vial — it will show the exact insulin-syringe units to draw, the concentration, and how many doses the vial holds.
Add 5 mL of bacteriostatic water to your 5 mg vial. That gives you about 50 doses of 100 mcg. For each dose, draw 10 units into a 100-unit insulin syringe.

Cautions
- Not approved for human use.
- GH response can fade with overuse.
- Possible cortisol/prolactin effects; caution with active cancer.
