First, welcome to Ology. How old are you? What would you estimate your body fat % to be?
An anavar/winstrol cycle is a terrible idea. First I would recommend getting your diet in line and putting on some quality muscle...you are tiny and don't have the proper natural base for running gear. What is a typical day's diet for you?
If you're dead set on running gear, go with a bread and butter test only cycle.
500mg test e/c per week for 12 weeks. Nolva and clomid for post cycle therapy (pct) and have an Aromatase inhibitor (AI) on hand in the event of estro-related sides.
