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 · low

    Hexarelin (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

    Compatible

    Hexarelin 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

    Compatible

    Hexarelin 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
