Deca Durabolin is the Organon brand name for nandrolone decanoate. World wide, Deca is one of the most popular injectable steroids. It's popularity is likely due to the fact that Deca exhibits significant anabolic effects with minimal androgenic side effects. Considered by many the best overall steroid for a man to use (side effects vs. results) Deca is most commonly injected once per week at a dosage of 200-400mg. With this amount, estrogen conversion is slight so gyno is usually not a problem. Also uncommon are problems with liver enzymes, blood pressure or cholesterol levels. At higher dosages, side effects may become increasingly more frequent, but this is still a very well tolerated drug. It should also be noted that in HIV studies, Deca has been shown not only to be effective at safely bringing up the lean bodyweight of patient but also to be beneficial to the immune system. For bodybuilding, Deca can effectively be incorporated in both mass and cutting cycles. One major drawback to Deca is that it can be detected in a drug screen for as long as a year after use. Unfortunately for many competitive athletes, this makes Deca and other nandrolone products off limits. Deca is also a comparatively expensive anabolic. Black market, 200mg of Deca will cost upwards of $20 in most instances. In the U.S., one would commonly find the Mexican veterinary version Norandren 50 from Brovel in Mexico. This is a 50ml vial of what is supposed to be 50mg/ml nandrolone decanoate. Brovel Labs however, has a reputation for underdosing their products and this may be closer to 35mg/ml. Extraboline and Deca-Durabolin from Greece are also commonly found, Extraboline usually being slightly cheaper. Retabolil from Bulgaria ("Russian Deca") is another commonly found product. These ampules come one to a box and in 25mg and 50mg strength, the 50mg being almost exclusively brought to the US. The ampules have no band around the neck and no scoring. The larger
box comes with a file, which is required to open this ampule. These ampules have been made with 2 labeling styles, the first being a very easy to rub off red and yellow silk-screen directly on the glass and the other being the simple paper label with gray text. Deca is also widely counterfeited in countless forms so caution should be taken when purchasing this on the black market.
