Equipoise (Boldenone Undecylenate) is a structurally altered form of testosterone. It is a very slight change in an added double bond at the carbon one and two position. This double bond greatly reduces the hormone’s androgenicity, as well as estrogenic nature. It is then attached to the very large or long Undecylenate ester, which is responsible for controlling the release of the hormone once administered into the body. The Undecylenate ester allows for a peak release in Boldenone approximately 3-4 days after injection, with a slow continuous release of the hormone to follow for approximately 21 days.
