First of all, Zambon, the new company now know as Desma, which produces Winstrol, doesn't produce Deca. Secondly, if they did they wouldn't put it in a multidose vial. Reminds me of the Organon 'Dbol' we wrote about earlier. This stuff doesn't even come in a box, but instead the 10ml 200mg/ml nandrolone decanoate fake is packaged in a baggie. And not surprisingly, after reading some reports by those brave enough to try this Deca, reviews seem to be quite negative. Its better to stick to Norma Decas for human grade or a more reputable UG option if you want to run Deca.
