GH Secretagogues

Hexarelin

Preclinical, limited human dataGrowth hormone secretagogue, ghrelin receptor agonist

Also published as Examorelin

A synthetic hexapeptide secretagogue, one of the more potent of the class for growth hormone release. Unusually, it also binds CD36, which is why a separate cardiac literature exists for it.

Where it came from

Developed in Italy in the 1990s as part of the growth hormone releasing peptide series that followed GHRP-6.

What the literature examines

  • GHS-R1a mediated growth hormone release in humans and animals
  • CD36 binding and cardiovascular effects independent of growth hormone
  • Cardiac protection in ischaemia models
  • Receptor desensitisation with repeated exposure

State of the evidence

Furthest it has gotPreclinical, limited human data

Human endocrine studies from the 1990s exist. No registration programme completed.

What a buyer should know

Desensitisation with continued exposure is documented for hexarelin specifically, more so than for the other secretagogues. It also raises cortisol and prolactin, which is exactly the selectivity problem ipamorelin was designed around.

Handling and stability

Lyophilised, water soluble.

Sequence

His-D-2-methyl-Trp-Ala-Trp-D-Phe-Lys-NH2
