An androstene is a monounsaturated derivative of androstane which is the basis of many steroids.
From my understanding, androstenediol converts to 1-test inside the body. The target hormone for both androstene & androstenediol is 1-test but androstenediol only needs to convert one time in the body to become the target hormone where as androstene needs to go through two conversations. So to answer your question, androstenediol is def the better of the two and I would say androstene is more of a water down hit or miss androstenediol.
1g or 1000mg of androstene per day.
