Nandrolone Undecanoate is an injectable form of the anabolic steroid nandrolone. It was once highly favored by athletes and bodybuilders for its ability to promote slow steady gains in lean mass with minimal estrogenic or androgenic side effects.

Nandrolone Undecanoate Structure

This drug's base ingredient is the anabolic steroid nandrolone. The ester applied here is one carbon atom longer than decanoate, and consequently forms a very slightly longer-lasting drug deposit at the site of injection. Nandrolone Undecanoate is an effective compound that produces quality, long-lasting muscle gains. This is because of the relatively long half-life of the drug (around 18 days). Even without a further protractedtherapeutic window, Nandrolone Undecanoate can be comfortably injected once every 1 to 2 weeks, which reflects its slow-acting nature.

Nandrolone Undecanoate For Bodybuilding

In bodybuilding, Nandrolone Undecanoate is often used for mass build-up, as it has a strong anabolic and moderate androgenic effect. Due to the severe impairment of the body's testosterone production, it is frequently injected with testosterone. Compared to Nandrolone Decanoate, the price and the need for frequent injections is a crucial drawback. For beginners and women the number of necessary injections is still within the scope.

Nandrolone Undecanoate Application

Nandrolone Undecanoate is used to promote weight gain following extensive surgery, chronic infection, or severe trauma, and in other cases that result in inadequate weight gain or maintenance. Nandrolone Undecanoate is also used to decrease muscle loss caused by treatment with corticosteroids and to reduce bone pain associated with osteoporosis.
