Ipamorelin vs GHRP-6: Comparing GH Secretagogues for Research (UK 2026)

Ipamorelin and GHRP-6 (Growth Hormone-Releasing Peptide-6) are both ghrelin receptor (GHS-R1a) agonists that stimulate growth hormone release from the anterior pituitary. Despite this shared mechanism, they differ significantly in receptor selectivity, GH puls

  • Ipamorelin and GHRP-6 (Growth Hormone-Releasing Peptide-6) are both ghrelin receptor (GHS-R1a) agonists that stimulate growth hormone release from the anterior pituitary. Despite this shared mechanism, they differ significantly in receptor selectivity, GH pulse profile, and co-secreted hormones — differences that substantially affect which compound is appropriate for different research questions.
