GHRP-2 Acetate vs GHRP-6 Acetate: Direct Comparison

GH Pulse Magnitude (100mcg dose) 2–4× baseline, peaks at 20–30 min Equivalent potency. Choice depends on secondary effects Ghrelin Receptor Affinity Moderate (selective for GHS-R1a) High (non-selective, binds GHS-R1a + CD36) GHRP-2 avoids peripheral ghrelin si

This comparison does not assign a generated winner or score.

  • GH Pulse Magnitude (100mcg dose)
  • 2–4× baseline, peaks at 20–30 min
  • Equivalent potency. Choice depends on secondary effects
  • Ghrelin Receptor Affinity
  • Moderate (selective for GHS-R1a)
  • High (non-selective, binds GHS-R1a + CD36)
  • GHRP-2 avoids peripheral ghrelin signaling
  • Appetite Stimulation
  • Minimal (10–20% incidence)
  • Strong (70–80% incidence within 60 min)
  • GHRP-6 confounds appetite-sensitive protocols
  • Cortisol Co-Secretion
  • 15–25% above baseline
  • 40–60% above baseline
  • GHRP-2 produces less HPA axis interference
  • Prolactin Elevation
  • Mild, dose-dependent (>200mcg)
  • Mild to moderate, dose-dependent
  • Minimal clinical difference at standard doses
  • Research Applications
  • Metabolic studies, sleep research, appetite-neutral protocols
  • Ghrelin pathway research, appetite stimulation studies
  • Select based on whether ghrelin activation is target or confound

Safety Comparison

Neither GHRP-2 nor GHRP-6 is FDA-approved for human use. Long-term human safety data for both is limited. The following reflects what is established in clinical research and commu…
