Potent GH-releasing peptide; stronger hunger and prolactin/cortisol effects than Ipamorelin.

How to picture it

GHRP-2 is a strong ghrelin-receptor agonist that pushes the pituitary for GH release with more spillover into appetite, cortisol, and prolactin than selective peers like ipamorelin. Picture a loud intercom that wakes GH effectively but also pings neighboring departments. Research uses it when pulse strength is the priority and selectivity is secondary.

Research focus & benefits

  • Robust GH-release research
  • Appetite and hormonal-spillover pathway studies
  • Historical secretagogue comparative work

Benefits describe research interest and pathway rationale — not guaranteed outcomes or medical advice. Research use only.

Overview

GHRP-2 is a second-generation growth hormone releasing peptide. It produces robust GH pulses but is less selective than Ipamorelin, often increasing appetite and sometimes cortisol/prolactin. Still used by some advanced users seeking stronger GH output.

Mechanism

Ghrelin receptor agonist amplifying pituitary GH release.

Research uses

  • GH deficiency diagnostics (historically)
  • Appetite and GH research

Research dosing notes

Usually multi-pulse subcutaneous protocols on empty stomach; hunger spike is expected.
