Hexarelin
Definition: A potent ghrelin receptor agonist studied for growth hormone release and possible cardioprotective signaling in pre-clinical models.
What is Hexarelin?
Hexarelin is a synthetic hexapeptide in the growth hormone secretagogue family. It is considered one of the more potent GH-releasing peptides and has been studied not only for endocrine stimulation but also for tissue-specific effects in the heart and vasculature.
How does Hexarelin work?
Hexarelin activates GHSR-1a and related cardiac binding sites, stimulating pituitary GH secretion while also engaging pathways linked to cardiomyocyte survival and anti-apoptotic signaling in experimental models. Its potency may increase the likelihood of endocrine side effects such as transient cortisol or prolactin changes.
Primary Documented Uses
- Research into growth hormone secretagogue potency
- Pre-clinical cardioprotection studies
- Experimental recovery and tissue-repair models
- Comparison compound for ipamorelin and GHRP analogs
Research Summary
Human studies show strong GH release after hexarelin administration. Animal and cellular studies suggest cardioprotective properties after ischemic injury and in models of cardiac dysfunction, but these findings remain experimental and have not translated into approved cardiovascular indications.
Legal and Regulatory Status
Hexarelin is not FDA-approved for human therapeutic use and is prohibited by WADA. It should be considered a research chemical outside regulated clinical trials.
