What is Sermorelin?

Sermorelin is a synthetic 29-amino acid peptide corresponding to the N-terminal active fragment of human Growth Hormone-Releasing Hormone (GHRH 1-29). The minimal active sequence of GHRH that retains full GH secretagogue activity — binds the GHRH receptor on anterior pituitary somatotrophs to stimulate pulsatile GH release and downstream IGF-1 production. Shorter half-life than full GHRH (44 amino acids) enables precise timing studies of GH pulse dynamics. Research use only.

Research Applications

GH Pulse Stimulation

Pituitary somatotroph activation, GH secretion amplitude and frequency modulation

GHRH Receptor Pharmacology

Receptor binding kinetics, cAMP/PKA signalling, receptor desensitisation studies

IGF-1 Axis Research

Hepatic IGF-1 production, somatomedin signalling, tissue anabolic response

Somatopause & GH Decline

Age-related GH axis attenuation, sermorelin vs GHRH comparison, therapeutic window

Minimal Active Sequence Studies

GHRH(1-29) vs full-length GHRH pharmacokinetic and pharmacodynamic comparison

Frequently Asked Questions

How do I reconstitute Sermorelin?
Add 1–2 mL bacteriostatic water to the lyophilized vial, directing liquid down the inner wall. Swirl gently until dissolved — clears within 1–2 minutes. Sermorelin is moderately soluble; the 15mg vial may benefit from 2 mL reconstitution volume.
How should Sermorelin be stored?
Store lyophilized vials at −20°C. Reconstituted solution is stable at 2–8°C for up to 3 weeks. Sermorelin has moderate stability — minimize light exposure and do not freeze reconstituted solution.
How does Sermorelin differ from full-length GHRH?
Sermorelin is GHRH(1-29) — the minimal 29 amino acid N-terminal sequence that retains full GH secretagogue activity. Full GHRH is 44 amino acids. Sermorelin has a shorter plasma half-life (~10–20 min vs ~50 min for GHRH analogs) making it useful for pulse timing and receptor kinetics research.
