FDA COMPOUNDING LIST (503A)

Ipamorelin is on FDA's 503A bulk-substances list (nominated for compounding, withdrawn by the nominator).

Compounded drugs containing Ipamorelin acetate may pose risk for immunogenicity for certain routes of administration due to the potential for aggregation or peptide-related impurities. Ipamorelin acetate also contains unnatural amino acids, which add to the complexity of peptide characterization. A study published in literature identified serious adverse events including death when ipamorelin was administered intravenously for improving gastric motility. FDA has not identified safety-related information regarding ipamorelin acetate via certain other injectable routes of administration. The agency lacks sufficient information to know whether the drug would cause harm if administered to humans via those routes.
