Description
GHRP-2 is a synthetic hexapeptide that acts as a ghrelin receptor agonist to potently stimulate the release of growth hormone from the pituitary.
Usage
Used in research to evaluate GH secretagogue activity, body composition changes, and metabolic effects.
Mechanism of Action
Binds to the growth hormone secretagogue receptor (GHSR-1a) in the hypothalamus and pituitary, triggering G-protein–coupled signaling that increases pulsatile GH secretion.
Benefits(4)
- Enhanced pulsatile growth hormone release
- Improved lean muscle mass
- Accelerated fat metabolism
- Increased appetite (via ghrelin receptor activation)
Side Effects(4)
- Transient increase in cortisol and prolactin
- Mild water retention
- Increased hunger
- Possible tingling or numbness at injection site
