GHRP-6
GHRP-6 (Growth Hormone Releasing Peptide-6) is one of the original GH secretagogues. It stimulates the pituitary gland to release growth hormone by acting on the ghrelin receptor. Notable for its strong appetite-stimulating effects, GHRP-6 is particularly useful for those looking to increase caloric intake during muscle-building phases. It also promotes fat metabolism, improves sleep quality, and supports recovery.
