Hexarelin, also called examorelin, is a hexapeptide acting on the ghrelin receptor. It has its own human dose-response study, which is more than most molecules in this group can claim. Sold as research material, not as a medicine.

What is in the vial

Three manufacturers, all in 10 mg vials of lyophilised powder. A 10 mg vial with 2 ml of bacteriostatic water gives 5 mg per millilitre; the arithmetic and the conversion into syringe units are in the guides on reconstitution and syringe units.

What the human study showed

A dose-response study in healthy adult men, published in December 1996 in the Journal of Clinical Endocrinology and Metabolism, reported dose-dependent rises in growth hormone, prolactin and cortisol, with prolactin rising by around 180 percent and the growth hormone curve reaching a plateau.

The most useful finding concerns combination: growth hormone releasing hormone given together with a small dose of hexarelin produced a large growth hormone pulse with a moderate prolactin rise and no rise in cortisol. The cortisol rise is therefore tied to the size of the hexarelin dose, not inherent to the molecule.

A plateau in the growth hormone curve has a plain consequence: above a certain point more compound stops adding growth hormone and only adds the prolactin and cortisol response. That is the opposite of how these peptides are usually advertised.

A second pathway, and its limits

A 2002 paper in Circulation Research showed hexarelin also binds CD36, a protein in heart muscle cells and vascular endothelium. That work was done in animals and isolated hearts, so nothing follows from it about therapeutic action in people.

How it compares in its group

Hexarelin sits alongside GHRP-2, GHRP-6 and ipamorelin as a ghrelin receptor secretagogue. It is the one with its own published dose-response curve in people, and also the one with the largest prolactin response in that curve. The four are placed side by side in the map of the differences.

Status

Hexarelin is not a registered medicine. It appears on the World Anti-Doping Agency prohibited list for 2026 in section S2.2.4 under the name examorelin, in the same entry as GHRP-1 through GHRP-6 and ipamorelin. No published study compares its potency directly with GHRP-2 in humans. We publish no dosing schedules.

Handling and verification

Questions

Is hexarelin the same as examorelin?

Yes. Examorelin is the name used on the World Anti-Doping Agency list for the same molecule.

Does it raise cortisol?

In the 1996 dose-response study, yes, dose-dependently. When a small dose was combined with GHRH there was no cortisol rise, which ties the effect to dose size.

Is it stronger than GHRP-2?

No published study compares the two directly in humans, so the ranking repeated online has no source behind it.

Is it allowed in sport?

No. It is listed as examorelin in section S2.2.4, prohibited at all times.
