Hexarelin is a synthetic peptide that has been widely investigated in laboratory settings for its role in growth hormone signaling and cardiovascular research. As a member of the growth hormone secretagogue (GHS) family, Hexarelin interacts with the Growth Hormone Secretagogue Receptor, a receptor involved in regulating hormone release and various metabolic pathways. In addition to its endocrine effects, researchers have explored how this peptide may influence cellular processes within cardiovascular tissue models.
