Peptide GHRP-6, also known as growth hormone-releasing peptide 6, is a synthetic hexapeptide that specifically stimulates natural growth hormone release from the anterior pituitary gland by pituitary somatotrophs. It acts by binding to ghrelin receptors and mimics the effects of ghrelin – natural endogenous hormone. It has been researched for several functions and effects as memory improvement, enhancement of tissue viability, scars regeneration, heart function or Parkinson’s disease neurons protection.
