Nandrolone undecanoate (brand names Dynabolon, Dynabolin, Psychobolan), or nandrolone undecylate is a synthetic androgen and anabolic steroid and nandrolone ester.
Nandrolone Undecanoate is a once popular anabolic steroid comprised of the active steroidal hormone Nandrolone attached to the very large Undecanoate ester. Very similar to Nandrolone Decanoate (Deca Durabolin), it’s Undecanoate ester is slightly larger providing an even longer lasting therapeutic window.
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 (okoli 8 days). Users report mild side effects, with the biggest side effect being water retention.
Nandrolone is most commonly found with a cypionate, laurate, decanoate or plenylpropionate ester. Briefly explained, the ester determines how much of the given hormone is released over a period of time. Longer esters such as decanoate peak slowly and can keep stable blood plasma levels up to ten days, shorter esters such as the phenylpropionate peak more rapidly but the half-live is shorter. Shorter esters usually release much more active hormone per mg than longer esters, and of course, allow the drugs effects to leave your system more quickly.
