CAS#: 193079-69-5

Description: Tabimorelin is a growth hormone releasing factor agonist potentially for the treatment of growth hormone deficit. Tabimorelin is a drug which acts as a potent, orally-active agonist of the ghrelin/growth hormone secretagogue receptor (GHSR) and growth hormone secretagogue, mimicking the effects of the endogenous peptide agonist ghrelin as a stimulator of growth hormone (GH) release.

Price and Availability




Tabimorelin is not in stock, but may be available through custom synthesis. For cost-effective reason, minimum 1 gram order is requested. The product will be characterized by NMR, HPLC and MS analysis. Purity (HPLC) is usually >98%. CoA, QC data, MSDS will be provided when product is successfully made. The estimated lead time is 2-3 months. Please send email to to inquire quote.
