Sermorelin
Sermorelin
Also known as: Geref, GRF 1-29, Sermorelin Acetate
Overview
Key Facts
Primary Goal: Research and therapeutic applications of Sermorelin
Binds GHRH receptors on anterior pituitary somatotrophs to stimulate GH synthesis and secretion. Preserves the natural negative feedback loop of the GH-IGF-1 axis.

200–500 mcg
once daily before bed
3-6 months
Benefits
- Restores natural GH pulsatility
- Improves sleep quality and deep sleep duration
- Supports healthy body composition
- Well-established safety profile from clinical use
- May improve skin elasticity and bone density over time
Side Effects
Mechanism of Action
Binds GHRH receptors on anterior pituitary somatotrophs to stimulate GH synthesis and secretion
Preserves the natural negative feedback loop of the GH-IGF-1 axis
Promotes GH release that follows the endogenous pulsatile pattern
Contraindications
Do not use this peptide if any of the following apply:
- Active malignancy
- Hypersensitivity to sermorelin or mannitol
- Pregnancy or breastfeeding
- Obesity-related GH suppression may reduce efficacy
Storage & Reconstitution
Unreconstituted (Powder)
Reconstituted (Mixed)
Research Summary
Sermorelin was FDA-approved in 1997 under the brand name Geref for pediatric GH deficiency diagnosis and treatment. Clinical trials demonstrated its ability to restore physiologic GH secretion patterns. It was voluntarily withdrawn from market in 2008 for commercial reasons, not safety concerns, and remains available through compounding pharmacies.
