Omnadren was originally manufactured by Polfa, but has since changed to Jelfa in Poland. Five amps come protected in a white paper or plastic holder within a pink and white box. Older boxes are grey and blue and may still be circulating on the black market. The amps are made with clear glass and are imprinted with red ink. The older amps will be imprinted with black ink instead. The ink has the tendency to smear off. There does not seem to be many fakes of Omnadren on the black market. The World Anabolic Review mentions a counterfeit in which the "Omnadren 250" is imprinted in the upper third of the box rather than the lower third. Supposedly, the whole package is printed in English rather than Polish. This may not be a counterfeit, but rather the result of an industrious businessman repackaging Omnadren for sale on the US market after the loose amps were smuggled into the country. In any case, this shouldn't be a concern since these counterfeit or repackaged ampules do not seem to be prevalent on the market at the time.
