Deca 300 is Nandrolone Decanoate which can be highly useful either as a “bulking” or “cutting” agent during cycles and it seems diet and dosages are the determining factors of whether a cycle with this drug will be one or the other. Due to its highly anabolic nature coupled with low androgenic properties it can be incorporated into a mass cycle, usually stacked with testosterone and a powerful oral like possibly Anadrol or Dbol. NPP can thus be part of a classic bulking cycle. For a cutting cycle Nandrolone is usually combined with other short-estered injectable anabolic steroids such as test prop or boldenone and one of the DHT derived orals such as Winstrol or Anavar. Nandrolone is said to produce good mass and strength gains in both cutting and bulking cycle phases. When planning a cutting cycle one must take caution if combining tren with nandrolone. Trenbolone Acetate, although a powerful drug for lean muscle gains, strength, and fat loss may also result in a difficult PCT protocol to regain natural testosterone production.
