Buy NPP 150 Online

Nandrolone phenylpropionate (NPP 150), or nandrolone phenpropionate, sold under the brand name Durabolin among others, is an androgen and anabolic steroid (AAS) medication which has been used primarily in the treatment of breast cancer and osteoporosis in women. It is given by injection into muscle once every week. Although it was widely used in the past, the drug has mostly been discontinued and hence is now mostly no longer available.

Side effects of NPP include symptoms of masculinization like acne, increased hair growth, voice changes, and increased sexual desire. The drug is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT). It has strong anabolic effects and weak androgenic effects, which give it a mild side effect profile and make it especially suitable for use in women and children. NPP is a nandrolone ester and a long-lasting prodrug of nandrolone in the body.

NPP was first described in 1957 and was introduced for medical use in 1959. It was the first nandrolone ester to be introduced, followed by nandrolone decanoate in 1962, and has been one of the most widely used nandrolone esters. However, in more recent times, the drug has been largely superseded by nandrolone decanoate, which is longer-acting and more convenient to use. In addition to its medical use, NPP is used to improve physique and performance. The drug is a controlled substance in many countries and so non-medical use is generally illicit

Medical uses

NPP 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.^[3] Historically, it has also had a variety of other uses.^[3] 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.^[2][15] 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.^[16][17]

Side effects

The most common side effects of NPP consist of virilization (masculinization) in women, including symptoms such as acne, hirsutism (increased body/facial hair growth), hoarseness of the voice, and voice deepening.^[3] However, relative to most other AAS, NPP has a greatly reduced propensity for virilization and such side effects are relatively uncommon at recommended dosages.^[3] At higher dosages and/or with long-term treatment they make increase in incidence and magnitude however.^[3] A variety of uncommon and rare side effects may also occur.^[3]
