Hexarelin, also called Examorelin, is a synthetic analogue of ghrelin and is closely related to GHRP-6. In fact, hexarelin and GHRP-6 differ from each other only slightly thanks the addition of two methyl groups to GHRP-6. Hexarelin, like many ghrelin analogues, is orally and sublingually active and highly selective. Hexarelin has been heavily researched for its effects on heart cell survival following ischemia and nutrient deprivation.


A study in rats investigating the ability of GHRP-6 to offset problems associated with heart failure found that the peptide reduces oxidative stress in heart failure and prevents myocardial remodeling from taking place. Remodeling is a pathological process associated with a decline in heart function and serious morbidity. Rats treated with GHRP-6 in this study had significant improvements in the function of their heart. These processes are thought to be mediated by GHRP-6 up-regulation of phosphatase and tensin homologue (PTEN) activity as well as down regulation of protein kinase B expression.


PTEN plays a role in cell regeneration while protein kinase B regulates cell survival. GHRP-6 is so effective in reducing cardiac remodeling that it shifts the balance of nervous system activity away from sympathetic stimulation (higher heart rate, higher blood pressure, etc.) toward parasympathetic dominance. This not only improves short- term health and outcomes, but reduces the need for medication over the long term and likely helps to prevent cardiac remodeling that is secondary to increased stress on the heart. Rats treated with GHRP-6 following a heart attack show substantial reductions in the size of the scar left behind.
