What is GHRP-2?
GHRP-2 is a synthetic growth hormone secretagogue peptide that mimics ghrelin-like signaling at the growth hormone secretagogue receptor. It was developed to stimulate pulsatile endogenous growth hormone release and has been studied in endocrine research, catabolic illness, and diagnostic contexts.
How does GHRP-2 work?
GHRP-2 binds the GHSR-1a receptor in the hypothalamus and pituitary, stimulating growth hormone secretion and reducing somatostatin inhibition. Compared with GHRP-6, it tends to produce strong GH pulses with somewhat less appetite stimulation, though it can still affect ACTH, cortisol, and prolactin in some settings.
Primary Documented Uses
- Research into endogenous growth hormone pulsatility
- Endocrine stimulation testing in some clinical contexts
- Experimental studies of recovery, lean mass, and sleep architecture
- Combination research with GHRH analogs such as sermorelin or CJC-1295
Research Summary
Human studies demonstrate that GHRP-2 can markedly increase growth hormone release after administration. Research has explored its diagnostic use for GH deficiency and its physiologic interaction with GHRH analogs, but clinical wellness claims remain insufficiently supported by large long-term trials.
Legal and Regulatory Status
GHRP-2 is not FDA-approved for general therapeutic use in the United States. It is prohibited in sport by WADA and is typically sold only for laboratory research.
