Ipamorelin IPA

A peptide that triggers growth hormone release while causing less of the unwanted stress-hormone increase seen with similar compounds. Small studies confirm it reliably and selectively raises growth hormone, though it has never gone through the full testing needed for drug approval.

Also known as Ipamorelin acetate, NNC-26-0161, Y9M3S784Z6, Aib-His-D-2-Nal-D-Phe-Lys-NH2, NNC 26-0161, Aib-His-2Nal-Phe-Lys-NH2, RefChem:148620, Ipamorelin [INN]
