Omnadren 250 is an oil-based injectable containing a blend of four different testosterone compounds: testosterone propionate, 30 mg; testosterone phenylpropionate, 60 mg; testosterone isohexanoate, 60 mg; and testosterone hexanoate, 100 mg. Because Omnadren contains four different testosterones, many people will compare it with Sustanon. Omnadren does contain testosterone propionate and testosterone phenylpropionate in the same strength as Sustanon; however, testosterone isohexanoate and testosterone hexanoate replace the testosterone isocaproate and testosterone decanoate in Sustanon. As a result, Omnadren has a very different effect than Sustanon. To begin with, users of Omnadren will experience a heavy water retention. This characteristic leads to rapid gains in size and strength, but also causes the muscles to look very smooth and watery. Unlike Sustanon, Omnadren readily converts to estrogen, which may cause gynecomastia. The estogen-linked side effects can be reduced or prevented with the simultaneous use of Nolvadex(tamoxifen citrate) and Proviron(mesterolone).
Omnadren dosages range from 250 mg every other week up to 1000 mg or more per day. A fairly safe and effective dosage would be in the range of 250-1000 mg per week. Omnadren is active in the body for a few weeks, but an injection should be taken at least once a week. Many athletes like to combine Omnadren with a strong anabolic like Deca(nandrolone decanoate) or Equipoise(boldenone undecylenate). Powerlifters and athletes who want a dramatic gain in mass and strength prefer to stack Omnadren with the heavy orals such as Anadrol(oxymetholone) and Dianabol(methandrostenlone). Omnadren has a limited use in contest preparation due to the heavy water retention it causes.
A year or two ago, Omnadren was rare on the US black market. However, in the past several months the market has been flooded with Omnadren smuggled into the country from Poland. To give an example, 500,000 ampules of Omnadren were supposedly seized in a recent drug bust after a Polish pharmacy tipped off the DEA. With the increasing availability of this compound, it is becoming extremely popular on the black market. 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.
