What Hexarelin is
Hexarelin (examorelin) is one of the most potent synthetic growth-hormone secretagogues in the ghrelin-mimetic class. It produces large growth-hormone pulses but is known for receptor desensitization with continued use, and it raises cortisol and prolactin. It is unapproved and prohibited in sport.
Research depth: 2/5 Early human and preclinical studies confirm potent GH release with desensitization; not approved. Human trials: Early pharmacology studies. This measures how much has been studied — counting animal and laboratory work — not whether it works for you.
How Hexarelin works
It mimics ghrelin at the GHSR-1a receptor, producing a strong growth-hormone pulse, and also has ghrelin-receptor-independent effects on the heart in animal models. Repeated dosing downregulates the receptor response, so the effect diminishes over time. It also elevates cortisol and prolactin.
Hexarelin side effects
Commonly reported
- Injection-site reactions
- Increased hunger
- Water retention
- Elevated cortisol and prolactin
- Flushing
Serious — seek medical care
- Pituitary desensitization with continued use blunts the response
- Raises cortisol and prolactin
- Prohibited in sport by WADA
This list is not exhaustive. Report anything unexpected to the clinician who prescribed it. If you have severe abdominal pain, trouble breathing, or signs of an allergic reaction, seek care the same day. See also our guide to peptide side effects by class.
A worked example
A 5 mg vial reconstituted with 2 mL of bacteriostatic water gives 2.5 mg/mL. A 200 mcg dose is then 0.08 mL — about 8 units on a 100-unit insulin syringe, giving roughly 25 doses per vial before accounting for residual volume left in the vial and syringe.

Common questions
How does hexarelin compare to other secretagogues?
Hexarelin is among the most potent GH-releasing peptides of its class, but the pituitary tends to desensitize to it with continued use, blunting the response over time. It also raises cortisol and prolactin.
Is hexarelin approved?
No. Hexarelin is a research peptide with no approved human use, and it is prohibited in sport by WADA.
