Science-backed research overview for this compound
GHRP-2 (Growth Hormone Releasing Peptide-2, or Pralmorelin) is a synthetic hexapeptide that acts as a potent secretagogue for Growth Hormone. It is part of the second generation of GHRPs and is known for its high selectivity and efficacy in laboratory research.
GHRP-2 works by mimicking the action of the natural hormone ghrelin. It binds to the Growth Hormone Secretagogue Receptor (GHSR) in the pituitary gland and hypothalamus. This triggers a robust release of GH while also slightly increasing appetite and suppressing somatostatin, the hormone that inhibits GH release.
Research indicates that GHRP-2 is highly effective at raising systemic IGF-1 levels, which supports tissue repair and muscle growth. It is also being studied for its anti-inflammatory effects and its ability to protect cardiac tissue from oxidative stress, making it a versatile tool for longevity science.
