China Warehouse Sermorelin 15mg | 10-Vial Kit | GHRH(1-29) fragment — pituitary GH secretagogue for GH pulse dynamics, IGF-1 axis, and anti-aging research. ≥99% HPLC purity, Janoshik COA. Research use only. International shipping: 7–14 days
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.

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.
