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 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 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
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
Research Overview
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.
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.
