World wide & quot;Deca& quot; is one of the most widely used anabolic steroids. Its popularity is due to the simple fact that it exhibits many very favorable properties.

Structurally nandrolone is very similar to testosterone, although it lacks a carbon atom at the 19th position (hence its other name 19-nortestosterone). The resulting structure is a steroid that exhibits much weaker androgenic properties than testosterone. Of primary interest is the fact that nandrolone will not break down to a more potent metabolite in androgen target tissues.

You may remember this is a significant problem with testosterone. Although nandrolone does undergo reduction via the same (5-alpha reductase) enzyme that produces DHT from testosterone, the result in this case is dihydronandrolone.

In earlier years, testosterone and nandrolone were the only pharmaceutical injectables that were both widely available to bodybuilders and economical. Estrogen control did not then exist. For this reason, Deca’s low aromatizing properties were then quite useful. Deca therefore won wide popularity.

Deca needs to be taken over long periods of time (cycles of 12 weeks minimum) for it to be effective.Deca is not known as a very & quot;fast& quot; builder. The muscle building effect of this drug is quite noticeable, but not dramatic. The slow onset and mild properties of this steroid therefore make it more suited for cycles with a longer duration. In general one can expect to gain muscle weight at about half the rate of that with an equal amount of testosterone.
