I've done long winny cycles, and I have stopped the practice. It is unwise. I will now only use winny for FOUR WEEKS at a time, although it is my favorite steroid for cutting. I use 100mg/day. I consider fina to be considerably less harsh than winstrol. I will use 100-150mg/day of fina for as long as it lasts, which is to say, 10-12 weeks. I just put the winny on top at the end. Incidentally, milk thistle does nothing for your liver to protect it from steroid abuse. try ALA and Calcium D-Glucarate, along with N-acetyl cystein. That oughtta help out a bit.
Just an afterthought...fina will add muscle and burn fat better than winny, but the look is nota lined out and polished. Also, it will quickly vanish after you stop, whereas winny will give you a look that stays with you for quite some time.
I hear that oxandralone is the best for stripping that last bit of fat, and next month I will be able to contribute my experience with that stuff. We'll see, eh?
