Potent GH Release

GHRP-2 is considered the most potent GHRP in terms of raw GH release amplitude. It produces larger GH pulses than ipamorelin, GHRP-6, or hexarelin at equivalent doses. It is approved as a diagnostic agent for GH deficiency in Japan (pralmorelin), validating its GH-releasing potency.

GHRH Synergy

GHRP-2 combined with a GHRH analog (CJC-1295, sermorelin) produces GH release significantly greater than either alone. GHRH initiates the GH pulse; GHRP-2 amplifies it through the complementary ghrelin receptor pathway.

Body Composition Effects

Elevated GH promotes lipolysis, protein synthesis, and lean mass preservation. GHRP-2's potent GH elevation translates to improved body composition, enhanced recovery, and better sleep quality — though cortisol and prolactin elevations partially counteract benefits compared to cleaner alternatives.
