A potent growth hormone releasing peptide that also binds a heart receptor (CD36). Its growth hormone effect fades with steady use.

Evidence: Limited human research
Half-life: Short

Is hexarelin FDA-approved?

Not approved by the FDA. Products sold online as "research chemicals" aren't checked for purity, sterility or dose.

Is hexarelin banned in sport?

Banned in sport by the World Anti-Doping Agency (WADA).

Overview

Hexarelin is a relative of GHRP-6 that causes a strong growth hormone release. Studies found the response weakens with long-term use and recovers after stopping. It also binds CD36 in heart tissue, and small human and animal studies point to heart effects separate from growth hormone.

How it works

It switches on the ghrelin receptor (growth hormone release) and CD36 (heart and blood vessels).

How long does hexarelin stay in the body?

Short; not well established.

What it's studied for

Growth hormone release
Heart function

Reported side effects

Higher cortisol and prolactin
Weaker effect over time
