I notice that you are in Abu Dhabi, is that right? If so you have access to soome great instruction there, Sheik Tahnoon has a great training center there but anyway back to your original point, you really don't need winstrol, first of all it is really rough on your liver (which by the way can lead to a loss in endurance). You really should stick to the mainstays in the sport, Equipoise (also known as boldenone which you'll recognize since many fighters have failed their steroid tests using it) is really what you want to look into. You also mentioned anavar which is a good choice.
