GHRP-2 (growth hormone-releasing peptide 2, also called pralmorelin) is a synthetic peptide that activates the ghrelin receptor (GHS-R1a) to stimulate the pituitary to release growth hormone. It is one of the classic growth hormone secretagogues studied in endocrine research. Helix North discusses it as a research compound and does not currently supply it.

How does GHRP-2 work?

GHRP-2 binds the ghrelin receptor (GHS-R1a) on the pituitary and hypothalamus, prompting a strong pulse of growth hormone release and appearing to ease the somatostatin brake that normally limits it. It mimics ghrelin at that receptor, which is why it also tends to stimulate appetite. This is research-mechanism context, not a human therapeutic recommendation.

How is GHRP-2 different from ipamorelin?

Both are growth hormone-releasing peptides acting on the ghrelin receptor, but they differ in selectivity. GHRP-2 produces a strong GH pulse but also raises cortisol, prolactin and appetite; ipamorelin is more selective and drives GH release with fewer of those additional effects. Researchers choose between them based on how clean a signal the study requires.

Why is GHRP-2 paired with a GHRH analog?

Growth hormone release is balanced between GHRH (an accelerator) and somatostatin (a brake). GHRP-2 works through the ghrelin receptor, a different pathway from GHRH, so pairing it with a GHRH analog such as CJC-1295 engages both pathways at once and produces a larger, synergistic pulse than either alone.

Is GHRP-2 available in Canada for research?

GHRP-2 is not currently part of the Helix North catalog. Researchers studying recovery and tissue-repair peptides can explore BPC-157 and TB-500. Any peptide Helix North supplies is provided strictly for laboratory research, not for human or veterinary use.
