GHRP-6 Acetate vs Other Growth Hormone Secretagogues: Protocol Comparison

GHRP-6 Acetate 1–3 mcg/kg 2–3x daily 3 hours pre, 30 min post 90–120 minutes Moderate. Cycling recommended after 8–12 weeks Most forgiving timing-wise among GHRPs; strong appetite stimulation limits use in caloric restriction protocols GHRP-2 Moderate. Similar

  • GHRP-6 Acetate
  • 1–3 mcg/kg
  • 2–3x daily
  • 3 hours pre, 30 min post
  • 90–120 minutes
  • Moderate. Cycling recommended after 8–12 weeks
  • Most forgiving timing-wise among GHRPs; strong appetite stimulation limits use in caloric restriction protocols
  • GHRP-2
  • Moderate. Similar to GHRP-6
  • Produces higher peak GH amplitude than GHRP-6 but with greater cortisol and prolactin co-release
  • Ipamorelin
  • 200–300 mcg flat dose
  • 2 hours pre, 20 min post
  • 2–3 hours
  • Low. Minimal receptor downregulation
  • Cleanest GH pulse profile with negligible cortisol/prolactin elevation; more expensive per dose than GHRP-6
  • Hexarelin
  • 100–200 mcg
  • 1–2x daily
  • High. Rapid desensitisation within 4–6 weeks
  • Strongest GH release among peptides but unsustainable long-term; reserved for short pulse protocols
  • MK-677 (Ibutamoren)
  • 10–25 mg oral
  • Once daily
  • No fasting required
  • 24-hour elevation
  • Moderate. Appetite and water retention increase over time
  • Non-peptide ghrelin mimetic; convenient oral dosing but lacks pulsatile release pattern
  • This comparison shows GHRP-6 acetate occupies the middle ground: stronger GH release than ipamorelin, less desensitisation than hexarelin, and simpler dosing than peptide stacks. The appetite stimulation it causes. Mediated by ghrelin receptor activation. Makes it poorly suited for fat loss protocols but valuable in research contexts prioritising anabolic signaling and recovery acceleration. Researchers seeking appetite suppression should consider Tesofensine as an alternative approach to metabolic research.
