Background

About Sermorelin Peptide UK

Sermorelin is a synthetic peptide corresponding to the first 29 amino acids of human growth-hormone-releasing hormone, the region responsible for receptor activity. It is therefore used in endocrine research as a defined GHRH-receptor agonist.

Research

Sermorelin Research

Sermorelin research examines GHRH receptor pharmacology, pituitary somatotroph signalling, growth-hormone release and downstream endocrine feedback, with structure-activity studies mapping the receptor-active region of the GHRH(1-29) sequence in detail (Learn more). Its relatively short sequence allows researchers to study the active N-terminal region of GHRH without using the full endogenous peptide, alongside related growth-hormone-secretagogue peptides such as [CJC-1295 with DAC] and [Ipamorelin].

Questions

Sermorelin Frequently Asked Questions

What is Sermorelin?

Sermorelin is a synthetic 29-amino-acid analogue corresponding to the active N-terminal region of human GHRH, supplied by Crown Peptides in 5mg and 10mg vials.

What receptor does Sermorelin target in research?

It is studied through the growth-hormone-releasing hormone receptor.

What is Sermorelin researched for?

Research includes pituitary signalling, growth-hormone release, GHRH receptor pharmacology and endocrine feedback.

Why is Sermorelin only 29 amino acids long?

The first 29 amino acids of GHRH contain the receptor-active region, allowing this shorter sequence to be studied independently.

How is Sermorelin tested?

HPLC and Mass Spectrometry can assess peptide purity and identity, with exact batch results recorded on the Certificate of Analysis.
