Interestingly, the most amazing finding with hexarelin was its ability to act on cardiac receptors separate from the GH releasing properties. The peptide can directly aid in cardio protective left ventricular pressure issues, as well as, help healing scar tissue on the heart. Studies on lean and obese lab rats concluded that while lean rats were able to take advantage of the GH plasma increase better than the obese rats (the healthier the rat the more hexarelin effectively produced and utilized GH), obese rats did not see the same advantage. Separate from the studies that monitored GH, both lean and obese rats both received all of the cardio protective properties of hexarelin.
