GHRP-2 is one of the most potent and widely studied synthetic growth hormone secretagogues (GHS) developed in the 1990s by Tulane University and Merck. It acts primarily via the growth hormone secretagogue receptor (GHS-R1a/ghrelin receptor) to trigger rapid, dose-dependent GH pulses while also exhibiting modest ACTH, cortisol, and prolactin elevation — making it a valuable tool for comparing selective vs. non-selective GHRP profiles. This research-grade lyophilized powder is synthesized under strict quality controls and provided with full analytical documentation, ideal for neuroendocrine, metabolic, and performance physiology research.

Key Scientific

  • High-purity GHRP-2 Acetate (≥ 98% by HPLC/MS, acetate salt form)
  • Verified hexapeptide sequence: D-Ala-D-(β-naphthyl)-Ala-Ala-Trp-D-Phe-Lys-NH₂
  • Lyophilized formulation for maximum long-term stability
  • Full Certificate of Analysis (COA) with HPLC, MS, and amino acid analysis
  • Manufactured in GMP-aligned, ISO-compliant facilities
  • Ideal for GH pulsatility, GHS-R1a binding, and stress-axis interaction studies

Research-Referenced Attributes (Based on scientific literature; not intended as therapeutic claims.)

  • Most potent GHRP: 3–5× stronger GH release than GHRP-6 at equivalent doses
  • Rapid onset (peak GH within 15–30 min) with dose-dependent pulses up to 30–50× baseline
  • Increases appetite via ghrelin receptor activation (stronger than Ipamorelin/GHRP-6)
  • Mild ACTH/cortisol and prolactin elevation (unlike Ipamorelin)
  • Synergistic with GHRH analogs (CJC-1295, Sermorelin) for 5–10× amplified GH response
  • Valuable in pituitary challenge testing, cachexia, and growth hormone deficiency models

Why Researchers Choose Nationwide Peptides GHRP-2 Acetate

  • Exact clinical-research sequence used in original Merck/Tulane studies
  • Highest documented GH-releasing potency among GHRP class
  • Transparent analytical data (HPLC >98%, MS confirmation)
  • Trusted by endocrinology, metabolism, and performance physiology laboratories
  • Competitive research pricing with bulk options

Storage & Handling

  • Store lyophilized powder at –4 °F (long-term) or 39.2 °F (short-term)
  • Store in a tightly sealed container and protect from light, moisture, air exposure, and elevated temperatures.
  • Reconstitute only with bacteriostatic water or sterile saline (typical concentration 2–5 mg/mL)
  • Reconstituted solutions stable at 39.2 °F for up to 4 weeks; avoid repeated freeze-thaw cycles
  • Use appropriate PPE and aseptic technique
