Pharmaceutical Raw Material Nandrolone Undecylate CAS: 862-89-5 
 

Nandrolone undecanoate is an injectable form of the anabolic steroid nandrolone,like the shorter acting Nandrolone Decanoate (Deca-Durabolin), has been used to produce steady and significant gains in strength and 'high quality' mass (lean mass that is more likely to remain post-drug-use).  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 undecylate 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. 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 is a man-made steroid, similar to the naturally occurring steroid testosterone. 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.

Users report mild side effects, with the biggest side effect being water retention.
