Bei den ersten Anzeichen von Herpes eingenommen, 2 - 3 mal tgl und der Herpes breitet sich kaum aus und heilt sehr schnell ab. Für oft Betroffene wird die vorbeugende Einnahme empfohlen, eind Kapsel am Tag reicht aus

Its for my cats

This helps with eye infection and discharge in kittens, runny nose and sneezing in adult cats. DO NOT give this to your cat for more then two weeks in a row. It may cause a deficiency in another amino acid
