Research Background
Sermorelin is the 29-amino-acid N-terminal fragment of growth-hormone-releasing hormone, GHRH(1-29), and corresponds to the shortest sequence that retains full GHRH-receptor activity. Because GHRH acts at the pituitary receptor rather than the ghrelin receptor, sermorelin is the classic comparator in research contrasting GHRH-receptor with ghrelin-receptor secretagogue signalling.

FAQ
What is Sermorelin?
Sermorelin is the GHRH(1-29) fragment (CAS 86168-78-7), a 29-amino-acid peptide and the classic GHRH-receptor agonist used in growth-hormone-axis research.
How does Sermorelin differ from Ipamorelin or GHRP-2?
Sermorelin acts on the GHRH receptor. Ipamorelin, GHRP-2 and GHRP-6 act on the ghrelin receptor. Research designs comparing the two classes test different upstream signalling routes to GH release.
Which kit sizes are stocked?
5 mg and 10 mg × 10-vial kits; custom configurations on request.
What documentation ships with the order?
Batch-specific COA (HPLC purity, MS identity), commercial invoice and packing list; full spectra on request.
