cycle is way too short , not worth the shut down. PCT is way to close to cycle end (sustanon has long esters that take time to clear) . Also Winny isn't going to do much of anything for you at 16% body fat . winny can help you look lean, dry, hard, and full , but if your covered with 16% body fat then theres no way to see any of that.

I'd just stick with a simple 8-12 week Test only cycle and re-evaluate from there.
