How This Works
GHRP-2 is a synthetic hexapeptide that binds to the ghrelin receptor (GHS-R1a), stimulating growth hormone release from the pituitary. It produces stronger GH release than Ipamorelin but with more moderate effects on appetite, cortisol, and prolactin than GHRP-6 or Hexarelin. This balanced profile makes it suitable for users who want significant GH benefits without the extreme hunger of GHRP-6 or the desensitization issues of Hexarelin.
