Hexarelin Benefits

  • Strongest GH pulse among GHRPs
  • Cardioprotective effects
  • Muscle mass and strength gains
  • Fat loss through improved body composition
  • Enhanced recovery from training

GHRP-2 Benefits

  • Potent GH release (stronger than GHRP-6)
  • Less appetite stimulation than GHRP-6
  • Improved body composition
  • Enhanced deep sleep quality
  • Cytoprotective properties

Hexarelin Dosing

Standard: 100-200 mcg SC 2-3 times daily|Pre-workout: 100 mcg 30 min before training|Pre-bed: 100 mcg for overnight GH pulse|Cycle: 8-12 weeks then 4 week break (desensitization)

GHRP-2 Dosing

Standard: 100-300 mcg SC 2-3 times daily|Pre-bed: 100-200 mcg for GH pulse during sleep|Combined: 100 mcg with CJC-1295 for synergy|Cycle: 8-16 weeks, 4 weeks off

Hexarelin Side Effects

  • Common: Increased appetite, water retention, tingling
  • Moderate: Cortisol and prolactin elevation (dose-dependent)
  • Notable: Desensitization occurs after 4-16 weeks of continuous use
  • Rare: Numbness in extremities

GHRP-2 Side Effects

  • Common: Mild appetite increase, water retention, tingling
  • Moderate: Cortisol elevation at higher doses
  • Rare: Prolactin increase, transient dizziness
  • Better tolerated than GHRP-6 overall

Research Overview

Hexarelin

Hexarelin has extensive pre-clinical and clinical evidence. Multiple human studies confirm potent GH release. Unique cardioprotective properties are well-documented. Note that receptor desensitization limits long-term continuous use.

GHRP-2

GHRP-2 has strong clinical evidence. Approved in Japan for diagnostic use. Multiple human studies confirm reliable GH stimulation with a favorable side effect profile compared to GHRP-6.
