Overview

GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide that potently stimulates growth hormone release through the ghrelin receptor. The short version: people usually care about it for potent gh release, appetite stimulation, body composition, but the strength of the evidence depends heavily on indication and study type.

GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide that potently stimulates growth hormone release through the ghrelin receptor. It produces one of the strongest GH pulses among the GHRP family, with significant effects on appetite stimulation, cortisol, and prolactin.

Developed as a research tool for studying GH secretion, GHRP-2 has been studied in clinical settings for GH deficiency and cachexia. It is more potent than GHRP-6 but less selective than Ipamorelin.

Research Snapshot

What the evidence says

Animal

GHRP-2 currently shows 0 registered trials from ClinicalTrials.gov, 56 PubMed trial publications (42 RCT-tagged), and 203 PubMed references matching the stored source query. Treat PubMed references as literature surface area, not a count of clinical trials.

Known vs uncertain

Known signals

  • 0 registered trials are tracked from ClinicalTrials.gov intervention records.
  • 56 PubMed clinical-trial publications are indexed.
  • 42 PubMed randomized controlled trial publications are indexed.
  • 203 PubMed references are tracked separately from trial counts and can include animal, in-vitro, review, mechanism, or clinical records.

Open questions

  • Evidence strength may vary by indication, route, formulation, and population.
  • Public anecdotes can highlight interest or concern but do not establish clinical efficacy.
  • Regulatory status and compounding access can change independently from the research literature.

Mechanism of Action

GHRP-2 acts as a ghrelin mimetic, binding to GHS-R1a receptors in both the pituitary and hypothalamus to stimulate GH release.

Key Research Benefits

One of the most potent GH-releasing peptides
Studied for significant GH elevation in clinical trials
Researched for anti-aging and body composition
Appetite stimulation (may benefit underweight research subjects)
Synergistic when combined with GHRH analogs like CJC-1295
