GHRP-2

Growth Hormone Releasing Peptide-2

Overview

GHRP-2 is considered one of the most potent growth hormone releasing peptides available. It stimulates GH release more effectively than GHRP-6 with less pronounced appetite stimulation, making it a preferred choice for those seeking strong GH elevation without excessive hunger.

Mechanism of Action

GHRP-2 binds to the GHS-R1a receptor with high affinity, triggering robust GH release from pituitary somatotrophs. It also suppresses somatostatin tone, amplifying the GH pulse. Compared to GHRP-6, it produces a stronger GH release per microgram while activating ghrelin-mediated hunger pathways to a lesser degree.

Notes

Best on empty stomach. Often considered a more refined alternative to GHRP-6 for those who do not want appetite stimulation. Excellent when combined with CJC-1295.

Potential Side Effects

Mild hunger increaseWater retentionPossible cortisol elevationTinglingProlactin increase (higher doses)
