8and20, if one is looking for strength gains quick at the beginning of a cycle, then you are right, do the anavar first. IMO it is better to start with Dianabol - methandrostenolone - and finish with Anavar - oxandrolone - . The reason I would do Anavar - oxandrolone - at the end is to harden the muscles and Anavar - oxandrolone - helps you keep more of your gains on the other compounds as well.
IMO run Anavar - oxandrolone - at atleast 60mg for 6 weeks.
