This comprehensive review positions ghrelin as a multi-system hormone with validated cardiovascular protection, immune modulation, reproductive regulation, and metabolic control — far beyond its original GH-releasing and appetite roles.
Key findingGhrelin's validated roles now span GH release, appetite, cardiovascular protection, anti-inflammatory immune modulation, reproductive function, pancre
What the researchers found
Ghrelin's validated roles now span GH release, appetite, cardiovascular protection, anti-inflammatory immune modulation, reproductive function, pancreatic regulation, and bone metabolism — establishing it as one of the body's most versatile peptide hormones.
Why it matters
Relevant for ghrp, hormone-optimization, cardiovascular, immune-function, receptor-signaling.
How the study worked
review study on ghrp, hormone-optimization.
