Nandrolone cyclotate () (developmental code name RS-3268R), or nandrolone ciclotate, also known as 19-nortestosterone 17ò-ciclotate, is a synthetic and injected anabolicâÂÂandrogenic steroid (AAS) of the nandrolone (19-nortestosterone) group which was never marketed. It is an androgen ester â specifically, the C17ò ciclotate (4-methylbicyclo[2.2.2]oct-2-ene-1-carboxylate) ester of nandrolone. Nandrolone cyclotate has potent and prolonged activity as an AAS when administered by intramuscular injection and is reported to have a similar duration of action to that of nandrolone decanoate via this route.
