DECA 300® (Nandrolone Decanoate) is a long acting, highly anabolic steroid with low androgenic effects. It is highly favored by bodybuilders for its ability to promote significant strength and lean muscle mass gains without strong androgenic side effects. Deca is not known as a very "fast" 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. Although active in the body for much longer, Deca is usually injected once or twice per week. Deca carries a relatively potent anabolic rating, slightly greater than testosterone. However, its total androgenic activity is much lower than testosterone, carrying an androgenic rating of only 37 compared to testosterone’s 100. Deca has the ability to enhance protein synthesis, inhibit glucocorticoid hormones, and promote enhanced IGF-1 output. Like many anabolic steroids, Deca also has the ability to increase nitrogen retention in the muscles.
