GH response to hexarelin or growth hormone-releasing hormone

Older age is associated with GH response to hexarelin or growth hormone-releasing hormone in humans.

“However, at each dose the GH responses to HEX or GHRH in E were lower (p < 0.05) than those in Y.”

Age-related variations in the neuroendocrine control, more than impaired receptor sensitivity, cause the reduction in the GH-releasing activity of GHRPs in human aging
