No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone1

In this study, Hexarelin was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Hexarelin.

    In pooled human hepatocytes incubated with alexamorelin for 3 h, the only metabolite detected was examorelin (hexarelin), from C-terminal cleavage of Ala.

    In plain wordsIn lab tests with human liver cells, alexamorelin broke down into hexarelin (examorelin) as the only metabolite found after 3 hours.

    Summary
    After 3 h of incubation with hepatocytes, only one metabolite (known as examorelin or hexarelin) was detected, resulting from the C-terminal cleavage of the Ala amino acid; this metabolic reaction is mediated by a carboxypeptidase.

    Summary · context
    In silico metabolite predictions were performed using GLORYx freeware, and in vitro incubations were conducted with pooled human hepatocytes from 10 donors.

    In this study, Hexarelin was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Hexarelin.
