Intraperitoneale Zufuhr von14CH3-Kreatinin in Ratten erhoht deren 24-h-Ausscheidung von radiomarkiertem Methyl-Guanidin im Urin, wahrend Tiere, die andere radiomarkierte potentielle Vorlaufer erhalten hatten, keine erhohte Ausscheidung zeigten. Diese in-vivo-Konversion von Kreatinin zu Methyl-Guanidin konnte nicht der Aktion gastrointestinaler Bakterien zugeschrieben werden, da die Ausscheidung von Methyl-Guanidin sowohl in antibiotikabehandelten als auch in sterilen Ratten ubereinstimmte.
