Research use only. Not FDA-approved. May increase appetite significantly.
Overview
GHRP-2 is one of the most well-studied Growth Hormone Releasing Peptides. It produces potent GH release and has been studied in multiple clinical settings including GH deficiency diagnosis and treatment. It elevates GH more than ipamorelin but less than hexarelin, with moderate cortisol and prolactin effects.
Mechanism of Action
GHRP-2 is a synthetic agonist of the ghrelin receptor (GHS-R1a). It stimulates GH release from the pituitary through both direct pituitary action and hypothalamic GHRH release. Also mildly stimulates appetite via ghrelin pathway activation.
Use Cases
- ✓GH deficiency testing and treatment
- ✓Muscle growth and recovery
- ✓Fat loss protocols
- ✓Anti-aging GH optimization
Research Summary
GHRP-2 has been studied in clinical trials as a GH stimulation test and therapeutic agent. Multiple studies confirm potent, dose-dependent GH release. Japanese regulatory approval has been sought for diagnostic use. Strong safety data from decades of research.
Typical Dosing
