Overview
GHRP-6 is an older growth hormone-releasing peptide known for stimulating natural growth hormone release and increasing appetite. It works through ghrelin-like receptors, which are involved in hunger signaling and GH secretion. GHRP-6 is often discussed for recovery, muscle support, body composition, and appetite stimulation. Because it may strongly increase hunger, it is sometimes associated with bulking or weight-gain goals rather than fat-loss programs. Its purpose is to activate growth hormone release while also influencing appetite-related pathways.
