Peptides · Growth-hormone axis (under FDA review)
Hexarelin
Hexapeptide GH secretagogue.
What it does
What Hexarelin is and why doctors prescribe it.
Hexarelin is a synthetic hexapeptide GH secretagogue. Research interest spans GH-axis stimulation and possible cardioprotective effects. Under FDA review.
How it works
Mechanism in plain English.
Like ipamorelin, hexarelin acts via the ghrelin receptor (GHS-R) to stimulate GH release. It also has reported affinity for CD36, with some evidence of cardiac-tissue effects in preclinical models. Selectivity profile is broader than ipamorelin's, with somewhat more potential for cortisol/prolactin elevation.
How long it's been studied
Research history.
Hexarelin was developed in the 1990s alongside other GH secretagogues. Clinical research includes work in cardiovascular and growth-hormone-axis applications. Cannot currently be compounded under 503A.
Dosing
Clinical context for the prescribing doctor.
Pending regulatory clarity.
This page is informational, not a dispensing aid. Hexarelin is dispensed only on a patient-specific prescription written by a licensed doctor for an identified patient. Compounded drugs are not FDA-approved and should not be evaluated using branded-drug trial data. Availability varies by state and prescribed medication.
How to access Hexarelin through RonanRx
Three paths.
Hexarelin is currently in Category 2 and not available for 503A compounding. RonanRx is tracking the FDA review and will notify partner clinics when the decision allows compounding access.
