What are your goals? If weight loss is your primary goal, don't use steroids, as there are much safer alternatives with less side effects associated to them. Definitely, you should not be using Winstrol, as you won't notice any results unless your BF% is below 12, which I doubt if you want to lose fat. While anavar can indeed help fat loss, it is not meant for this purpose, and it is just a side effect of increased metabolism. You don't want to get the suppression caused by anavar, as well as liver toxicity when you have such alternatives as Cardarine GW-501516. Besides, the 4 weeks on, and 2 weeks off schedule will only hurt you with steroids. It takes time for the steroids to build up in your system and start working, and they will almost immediately suppress your natural testosterone production. Then if you stop taking them, your natural test levels will be extremely low, and there will be no exogeneus hormone that will keep you going. So it will greatly hinder any sort of results you achieve. With steroids you must cycle them properly - take them all the weeks in a row, and then run a proper PCT afterwards in order to restore your natural testosterone production and to keep the gains made on cycle.
Better opt for Cardarine GW-501516 - it makes an awesome combo with N2Slin. It wil burn your fat, and yet maintain and even increase your lean mass. Besides, you will get a very good endurance, recovery and cardio boost with Cardarine GW, with no side effects at all and no suppression. Use 12.5 mgs ED for 12 weeks, and do N2Slin before meals. You will see that the results will be great, and there will be no side effects with it.
