<unk> , or<unk>  17β-acetate, is a synthetic estrane steroid and a derivative of nandrolone (19-nortestosterone). It is the C17β acetate ester of<unk> , which itself is δ9,11-19-nortestosterone (δ9,11-19-NT) or estra-4,9,11-trien-17β-ol-3-one. Other<unk>  esters include<unk>  enanthate,<unk>  hexahydrobenzylcarbonate, and<unk>  undecanoate. Structure–activity relationships<unk>  is a modified form of nandrolone. The structure of<unk>  is a 19-nor classification, which represents a structural change of the testosterone hormone.<unk>  lacks a carbon atom at the 19 position and carries a double bond at carbons 9 and 11. The position of these carbons slows its metabolism, which greatly increases its binding affinity to the AR, and inhibits it from undergoing aromatization into the corresponding estrogenic metabolite.<unk>  contains<unk>  modified with the addition of a carboxylic acid ester (acetic acid) at the 17β-hydroxyl group. This facilitates the slow release of the AAS from the area of injection.
