NANDROLONE DECANOATE is an injectable anabolic preparation containing a short-acting and a long-acting nandrolone ester. The short-acting phenylpropionate ester provides a rapid increase in serum nandrolone levels followed by a long-acting enanthate ester with a duration of action of 5 to 8 days. Nandrolone Decanoate 250 has the advantage of faster onset than the traditional nandrolone decanoate and faster clearance. Nandrolone Decanoate 250 accelerates muscle growth, stimulates appetite, increases red blood cell production, and improves bone density.
