Sermorelin Research Guide

Full name: Sermorelin Acetate (GHRH 1-29)

The biologically active fragment of GHRH (first 29 amino acids). Previously FDA-approved for GH deficiency in children. Stimulates natural pulsatile GH release. Now available through compounding pharmacies.

How Sermorelin Works

Binds GHRH receptors on anterior pituitary via cAMP-PKA pathway. Preserves natural feedback regulation and pulsatility unlike exogenous HGH.

Dosing Protocol

• Typical dose: 200-300 mcg
• Frequency: Once daily before bed
• Duration: 3-6 months
• Route: Subcutaneous injection

Reported Benefits

• Natural GH pulsatility preserved
• Improved sleep quality
• Body composition improvement
• Skin elasticity
• Long safety record

Potential Side Effects

• Injection site reaction
• Flushing
• Headache
• Dizziness

Research Citations

1. Long-term sermorelin therapy for adult GH deficiency (2018) - Six months increased IGF-1 by 30%, improved body composition and sleep quality without suppressing endogenous GH axis.
2. Sermorelin vs somatotropin for GH replacement (2020) - Achieved 70% of HGH effects on IGF-1 with superior safety profile and preserved pituitary function.
