GHRP Peptides

MK-677 (Ibutamoren) is an orally active, non-peptide growth hormone secretagogue that mimics the action of ghrelin at the GHS-R1a receptor. Research focuses on increasing GH and IGF-1 levels, improving sleep quality, body composition, and bone density.

GHRP-6 (Growth Hormone Releasing Peptide-6) is a hexapeptide that stimulates growth hormone release through the ghrelin receptor. Known for potent GH release but also significant appetite stimulation.

Hexarelin is a synthetic hexapeptide growth hormone secretagogue, considered one of the most potent GHRPs available. Also shows cardioprotective properties independent of GH release.

GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide that stimulates growth hormone secretion. Considered more potent than GHRP-6 with less appetite stimulation.
