What is GHRP-2?

GHRP-2 is a synthetic hexapeptide growth hormone secretagogue often considered the balanced choice in the GHRP family — more potent than GHRP-6 with better selectivity, though not as clean as Ipamorelin.

Research Applications

GH secretagogue research, appetite and feeding behavior studies, pituitary function assessment, and comparative GH-axis pharmacology.

Dosage Information (Research Use)

100-300 mcg subcutaneously, 1-3 times daily. Research use only.

Reconstitution & Handling

Standard BAC water reconstitution.

Half-Life & Pharmacokinetics

Approximately 1-2 hours.

Reported Observations in Literature

Moderate cortisol and prolactin elevation, increased appetite (less than GHRP-6), water retention, drowsiness.

How GHRP-2 Works

GHRP-2 acts on the ghrelin/GHS receptor to stimulate pituitary GH release. Produces a more robust GH response than GHRP-6 with less appetite stimulation, but more cortisol/prolactin elevation than Ipamorelin. Considered the strongest clinically-studied GHRP after Hexarelin.

Research Findings

Extensive pharmacological data available. Often used as a reference standard in GHRP comparative studies. Good balance of potency and selectivity.

Dosage & Administration

100-300 mcg subcutaneously, 1-3 times daily. Research use only.

Safety & Side Effects

Moderate cortisol and prolactin elevation, increased appetite (less than GHRP-6), water retention, drowsiness.

Important: All safety information is derived from published research, primarily animal studies. No controlled human clinical trial data exists unless explicitly noted. This compound is sold for research purposes only.
