Results from this study2

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

Studies that did not test the peptide alone2

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.

  1. 01AnimalNot a test of Hexarelin aloneAnimal study (in vivo)Pharmacokinetics

    In rats, a lipid matrix of soybean phosphatidyl choline and medium-chain monoacylglycerol increased the jejunal permeability of hexarelin about 20-fold, with and without a protease inhibitor.

    In plain wordsIn rats, a lipid delivery system raised the gut wall passage of hexarelin in the jejunum about 20-fold.

    Summary · context
    The aim of this study was to investigate if the effective in-situ permeability (Peff) of a new growth hormone-releasing peptide, hexarelin, along rat intestine was enhanced by a lipid matrix drug-delivery system comprising a mixture of soybean phosphatidyl choline and medium-chain monoacylglycerol (PC-MG).

    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.

    In rats, the lipid matrix did not increase the ileal and colonic permeability of hexarelin.

    In plain wordsIn rats, the lipid delivery system did not raise the passage of hexarelin through the ileum and colon.
