GHRP-6

BHuman Studies

Growth hormone releasing peptide · 6 amino acids

Not FDA ApprovedPrescription RequiredWADA Banned

GHRP-6 was one of the first synthetic GH secretagogues developed. It stimulates strong GH release but also significantly increases appetite through ghrelin receptor activation.

Mechanism of Action

Activates GHS-R1a receptors in the pituitary and hypothalamus. Stimulates GH release, increases appetite via ghrelin-like activity, and promotes gastric motility.

Benefits

  • Strong GH release demonstrated in human trials
  • Significant appetite stimulation
  • Neuroprotective properties explored
  • May support cardiac function
