This is educational information, not medical advice, and The Peptide University does not sell peptides, supplies, or supplements.

GHRP-2 (pralmorelin) is a synthetic growth-hormone-releasing peptide. It's investigational for general use and has been studied as a diagnostic agent for GH secretion; it's not an approved consumer product.
How it works
It activates the ghrelin/GH-secretagogue receptor to release the body's own GH, and acts synergistically with GHRH analogues (why it's paired with things like CJC-1295). It also mildly stimulates appetite.
The evidence
It produces potent, reproducible GH release in studies, which is why it's been explored diagnostically. Evidence for anti-aging or body-composition goals in humans remains unconfirmed.
Safety
Effects track GH stimulation — water retention, tingling, appetite changes, and possible cortisol/prolactin effects at higher exposures. Long-term human safety is not established.
FAQ
QHow is it different from ipamorelin?
Both are ghrelin-receptor GH secretagogues; ipamorelin is marketed as more selective (less cortisol/prolactin effect) than GHRP-2/6.
QIs it approved?
No — investigational; studied diagnostically but not an approved consumer medicine.
