Ipamorelin

Ipamorelin is a synthetic pentapeptide that stimulates growth hormone release by mimicking ghrelin at the GHS-R1a receptor. NOT FDA-approved for any indication. Sold illegally as a 'peptide supplement' for anti-aging and muscle growth. WADA-banned. Requires injection (not orally bioavailable). Used in research settings for GH deficiency. Drug quality is unregulated — peptide purity and sterility are major concerns. Our assessment: PRESCRIPTION-GRADE PEPTIDE being sold as a supplement. Avoid. --- *Reviewed by the Dose AI Research Team and Clinical Advisory Board* *Last updated: 2026-04-06*
