Sermorelin is the amidated 1-29 amino-acid fragment of human growth hormone-releasing hormone. This N-terminal segment retains biological activity at the GHRH receptor and is used experimentally to study pituitary growth-hormone release, receptor pharmacology, and endocrine feedback. A sermorelin prescription product was historically marketed in the United States but was discontinued; that history does not make a current research product an approved medicine.

Frequently Asked Questions
Quick answers to common questions.
Still have a question? It corresponds to the biologically active N-terminal 1-29 segment, with a C-terminal amide.
Both activate the GHRH receptor, but tesamorelin is a modified 44-residue analogue whereas sermorelin is the shorter 1-29 fragment.
