A quote from the profile:
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 drug’s effects to leave your system more quickly.
