The Book of Peptides is not a clinic and not your doctor. We do not sell, prescribe, recommend, or personalize any compound, and no grade or ranking here is an endorsement. None of the compounds covered are approved for the uses described here by the U.S. FDA, Australia's Therapeutic Goods Administration (TGA), New Zealand's Medsafe, or the equivalent regulator in most other countries.
Most are sold for laboratory research only, a few are prescription-only drugs, and some are controlled substances or banned in sport. Possessing or administering an unapproved compound outside an authorized setting may be unlawful wherever you live. Nothing here is a recommendation to buy, possess, or self-administer anything. Consult a licensed physician before any decision involving peptide use.

GHRP-1 is one of the earliest synthetic growth-hormone-releasing peptides, a ghrelin-receptor agonist that triggers pituitary GH release without the opioid activity of its parent compounds. Early pharmacology and dose-finding studies confirmed it acutely raises GH in humans, but it was largely abandoned in favour of GHRP-2, GHRP-6 and later ghrelin mimetics, so there is little modern clinical or long-term safety data. It is rarely stocked and mostly of historical/completeness interest rather than a compound with a meaningful evidence base behind current use.
