In my experience, Geneza is solid. I've been using them long before I hosted this Q/A. If anything some of the labs i've seen would suggest that their test is over dosed. You're on the right track with using test for a first cycle. Honestly, if you ran that alone, you would be fine. Of course, I would use an AI. I would steer far away from using injectable winstrol at this point of the game. You will find that doing steroid injections take some getting used to. You only want to inject each site, one time a wk, to avoid too much irritation and scar tissue, Plus, when you first start using, you'll find that the shots can be painful, lasting for several days. This is normal, but with Winstrol, you would need to do every day shots. This can get pretty tricky for a guy like me, that has been using for some time. I would never wish that on a newbie! Plus, although the win is injectable, it is still going to be harder on your liver. I wouldn't want you to put too much stress on your your body between that and anavar together. Overall, var is a safer drug, and I think it will be better, if your goal is to get leaner, AND add size. If you were doing a pure cut, I'd say go with oral win. It would get you drier. 

Remember that this plan is going to work only as well as your diet. You have to eat more calories than you need to maintain, in order to grow muscle, but you have to eat less cals than you need to maintain, in order to lose fat. It can be done but it can be a tricky balance and in a lot of case, guys end up not making nearly as much progress as they could. I would decide what is more important, cutting fat or adding muscle. If adding muscle is most important, You can use the anavar as a kick start. If cutting is the most important, the use anavar in the last 6 wks. 

1-12

Test E or Cyp 500mg EW

adex .5mg as needed, maybe 2-3x wk to start

then either first 6 or last 6 wks, Anavar 50mg ED

PCT starts 2 wks after last shot
