What is GHRP-2?
GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide that stimulates the release of growth hormone by acting on the ghrelin receptor (GHS-R1a). It is one of the most studied GH secretagogues due to its potent GH-releasing effect. Unlike ipamorelin, GHRP-2 may cause moderate increases in cortisol and prolactin.

FAQ
What is the difference between GHRP-2 and GHRP-6? Both stimulate GH release via the ghrelin receptor. GHRP-6 is known to cause stronger appetite stimulation and hunger, while GHRP-2 has a cleaner GH pulse with less hunger effect.
Can GHRP-2 be combined with CJC-1295? Yes, research often combines GHRP-2 with GHRH analogues like CJC-1295 for synergistic GH release. Use the multi-peptide calculator feature above.
