AICAR Benefits
- ✓Increases endurance capacity, enhances fatty acid oxidation, promotes mitochondrial biogenesis, improves glucose uptake, cardioprotective effects
Hexarelin Benefits
- ✓Strongest GH pulse among GHRPs
- ✓Cardioprotective effects
- ✓Muscle mass and strength gains
- ✓Fat loss through improved body composition
- ✓Enhanced recovery from training
AICAR Dosing
Research doses: 50-150 mg subcutaneously. Typically administered 30-60 minutes before physical activity in research settings.
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)
AICAR Side Effects
- ⚠Potential hypoglycemia, lactic acidosis at high doses, injection site reactions. Banned by WADA as a metabolic modulator.
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
AICAR
Salk Institute researchers demonstrated AICAR could increase endurance in sedentary mice by 44% without exercise training. Activates AMPK, triggering PGC-1α expression, mitochondrial biogenesis, and enhanced fatty acid β-oxidation.
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.
