What is hexarelin?

Hexarelin explained in plain English: what it is, what the research shows, side effects, legal status and dosage, plus a calculator for syringe units. There is no validated human dose, and this page doesn't invent one. Also called Examorelin.

Hexarelin is not approved for human use by the FDA or any other regulator. This page is educational; talk with a qualified healthcare professional before using any substance.

What is hexarelin?

Hexarelin is a lab-made peptide of six amino acids, a modified version of GHRP-6, developed in the early 1990s. Its official name is examorelin.

Like GHRP-6, it acts on the ghrelin receptor to make the pituitary gland release growth hormone.

What does hexarelin do?

Hexarelin causes one of the strongest growth hormone releases of any peptide of its type, and also raises cortisol and prolactin. The body adapts quickly, so the effect weakens with repeated use.

Researchers have also studied its effects on the heart, through a receptor called CD36, separate from growth hormone.

What does the research on hexarelin show?

Studies in the 1990s confirmed strong growth hormone release in people, and animal studies suggested possible heart-protective effects. It was never developed into a medicine, and there are no trials showing benefits for muscle, fat loss or aging.

Hexarelin side effects and risks

Reported side effects include flushing, higher cortisol and prolactin, water retention and higher blood sugar. Long-term effects are unknown, and products sold online aren’t checked for purity or strength.

Hexarelin is not approved for human use anywhere. It is banned in sport at all times by the World Anti-Doping Agency.

How do you reconstitute Hexarelin?

Hexarelin research vials hold a freeze-dried powder that is mixed with bacteriostatic water. The calculator above turns the vial size, the water and a dose into syringe units, and the reconstitution guide explains each step.

See the dosage section below for what is known about doses, with sources.

Hexarelin dosage

Hexarelin was never approved and has no validated human dose. Early studies tested single doses to measure hormone responses, not treatment doses.

There is no approved or validated human dose. This site does not repeat doses from forums, sellers or animal studies.

Medical disclaimer: this dosage information is for education only and comes from the source shown for each row. It is not medical advice and not a recommendation for you. Only a licensed prescriber who knows your health can decide whether Hexarelin is right for you and at what dose. Don't start, change or stop a medicine based on this page, and don't use research peptides or unapproved drugs based on trial doses.

Hexarelin concentration chart

The concentration of a Hexarelin vial depends only on its size and the water you add. Each unit on a U-100 syringe holds one hundredth of a mL.

Frequently asked questions

Is hexarelin stronger than GHRP-6?

For growth hormone, yes: it is one of the most potent peptides of its type. The body also gets used to it quickly, so its effect fades with repeated use.

Is hexarelin approved?

No. It was studied in the 1990s but never approved for any use.

Is hexarelin banned in sport?

Yes. The World Anti-Doping Agency bans growth hormone secretagogues like hexarelin at all times.
