Hexarelin
Typical dose
100 mcg
1–2×/day · SubQ · short 4–6 wk runs
Half-life
~70 minutes
What is Hexarelin?
The most potent synthetic GHRP. Produces large GH pulses but desensitizes faster than Ipamorelin.
How Hexarelin works
Potently activates GHSR-1a to stimulate GH release and also acts on CD36 scavenger receptors in cardiac tissue, providing cardioprotective effects independent of GH.
Benefits & uses
- GH pulse stimulation
- Cardioprotection
- Muscle growth
- Recovery
Common uses: Acute GH release, cardiac protection (independent GH pathway), recovery.
Hexarelin dosage
- Typical dose
- Typical: 100 mcg per dose SubQ, 1–2×/day. Short 4–6 week runs (desensitizes fast).
- Protocol notes
- 100-200mcg per injection. Lower doses minimize cortisol/prolactin elevation.
Hexarelin half-life
~70 minutes
Hexarelin side effects
Rapid receptor desensitization. Elevated cortisol and prolactin.
- Faster receptor desensitization than other GHRPs
- Cortisol and prolactin elevation
- Water retention
- Hunger increase (moderate)
Warnings & monitoring
- Research use only
- Raises cortisol and prolactin at higher doses
- Desensitization with prolonged use — cycle recommended
Preparation & storage
- Preparation
- Mix a 5 mg vial with 2 mL bac water → 2,500 mcg/mL. A 100 mcg dose = 0.04 mL = 4 units.
- Reconstitution
- Reconstitute a 5 mg vial with 2 mL BAC water → 2.5 mg/mL. A 100 mcg dose = 0.04 mL = 4 units on a U-100 syringe.
- Storage
- Lyophilized: refrigerate (2–8 °C). Reconstituted in BAC water: refrigerate, use within 4 weeks.
Hexarelin interactions
with CJC-1295
Compatible · lowHexarelin (GHRP) + CJC-1295 (GHRH analog) is a potent GH-releasing combination. Hexarelin is more potent than Ipamorelin but less selective. Cortisol and prolactin may also be elevated.
Timing: Administer together subcutaneously; fasted state preferred for maximum GH pulse
with CJC-1295
CompatibleHexarelin is a potent GHRP that synergizes with CJC-1295, but desensitizes more rapidly than Ipamorelin — cycle use and avoid daily dosing.
Timing: Inject together fasted; use 2–3x per week to reduce desensitization
with CJC-1295
CompatibleHexarelin is a potent GHRP; CJC-1295 sustains the resulting GH pulse. Watch cortisol/prolactin and rotate off hexarelin to preserve sensitivity.
Timing: Co-inject; cycle 4 weeks on, 2 off due to receptor desensitization
