Nandro D (Nandrolone Decanoate or Deca Durabolin) is an anabolic injectable compound which is rated as one of the best drugs for maintaining lean muscle mass and stimulating appetite. It provides a sharp spike in nandrolone release 24-48 hours following deep intramuscular injection, which steadily declines to near baseline levels approximately two weeks later. The mean depot-release half-life of nandrolone decanoate is 8 days.
It has the decanoate ester which provides a slow release of nandrolone from the site of injection and lasting for up to three weeks. It is very similar to testosterone in structure, although it lacks a carbon atom at the 19th position. Hence its other name is 19nortestosterone.
It is an anabolic androgenic steroid that has gained huge acceptability among professional athletes and bodybuilders. It is undoubtedly the second-best known injectable steroid after Testosterone. It exhibits relatively strong anabolic properties like testosterone.
It has tissue building activity accompanied by weak androgenic properties with the reduction of nandrolone to a weaker steroid, Dihydronandrolone. In the same androgen-responsive target tissues that potentate the action of testosterone by converting it to DHT. The mild properties of Nandro D have made it one of the most popular injectable steroids worldwide, highly favoured by athletes for its ability to promote significant strength and lean muscle mass gains without strong androgenic or estrogenic side effects.
Nandro D has actions similar to endogenous androgens. It has been known to cause unwanted adverse effects in women. The exogenous androgens suppress the gonadotropin-releasing hormone, thereby reducing the gonadotropic function of the pituitary through a negative feedback mechanism. Hence it results in a reduction of the luteinising hormone, endogenous testosterone and follicle-stimulating hormone.
Its average dose for physique or performance-enhancing purposes is in the range of 200-600mg per week, taken in cycles of 8 to 12 weeks in length.
This is not to be taken by women.
