Effects and side-effects
|This section does not cite any references or sources. (April 2009)|
Boldenone was synthesized in an attempt to create a long-acting injectable methandrostenolone (Dianabol), for androgen deficiency disorders. Boldenone acts similar to methandrostenolone with less adverse androgenic effects. It has a very long half-life, and can show up on a steroid test for up to 5 months, due to the long undecylenate ester attached to the parent steroid. Trace amounts of the drug can easily be detected for months after discontinued use.
