Winny from weeks 5-12 is a bad idea. That is 7 weeks. Im not concerned about your liver, but I have a feeling your joints will be killing you by the time its down. Your not going to get much benefit from the winny if your bulking, and if your cutting, apart from helping you hold onto muscle/strength, your not going to see any hardness from it unless your really low in bodyfat. I would just avoid it altogether, until a future cycle. But if your dead set on it, think about running it from week 10-14, two weeks past when you drop your test-e, so you still have high androgen levels while the test clears out, just before you begin your PCT.
