苯丙酸诺龙，DURABOLIN-NPP（GENENGIN）brand of Nandrolone phenylpropionate. Nandrolone phenylpropionate has been used mainly in the treatment of advanced breast cancer in women and as an adjunct therapy for the treatment of senile or postmenopausal osteoporosis in women.Historically, it has also had a variety of other uses.Because of its reduced androgenic effects, the drug has not generally been used in androgen replacement therapy for androgen deficiency in men and has instead been used for solely for anabolic indications.However, nandrolone esters have more recently been proposed for the treatment of androgen deficiency in men due to favorable properties including their high ratio of anabolic to androgenic effects and consequent much lower risk of prostate enlargement, prostate cancer, and scalp hair loss relative to testosterone.

Nandrolone phenylpropionate is used for physique- and performance-enhancing purposes by competitive athletes, bodybuilders, and powerlifters.Nandrolone esters have been said to be the most popular AAS used by bodybuilders and in sports.This is in part due to the high ratio of anabolic to androgenic effect of nandrolone and its weak propensity for androgenic and estrogenic side effects.
