Overview

A GHRH (1-29) analog historically prescribed to assess and stimulate growth-hormone secretion. Short-acting and biomimetic.

Mechanism of action

Binds pituitary GHRH receptors to stimulate natural GH release, preserving feedback regulation.

Typical protocol

100–300 mcg subQ at night, often cycled 3–6 months.

Storage

Reconstituted: refrigerated, ~2–3 weeks.
