- ✓Improved body composition
- ✓Enhanced recovery from training
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-6 Dosing
Standard: 100-300 mcg SC 2-3 times daily|Pre-workout: 100 mcg 30 min before training|Pre-bed: 100-200 mcg for overnight GH pulse
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-6 Side Effects
- ⚠Common: Increased appetite (significant), water retention, tingling
- ⚠Moderate: Cortisol elevation (dose-dependent), lethargy
- ⚠Rare: Elevated prolactin at high doses
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-6
GHRP-6 has solid pre-clinical and clinical evidence for GH stimulation. Well-characterized pharmacology. More appetite stimulation than Ipamorelin due to ghrelin receptor activation.
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.
