I understand what you're saying, but I stand by my last post. Again, you can use the same drugs for either type of cycle, but you are correct, when it comes to a comp cycle, some drugs are better left out of the equation, especially toward the end of the cycle. This is not because they will cause unwanted fat gain, but rather they simply cause one to hold more water then other drugs.
You mentioned how no one would use winny in a bulking cycle...well, in my case this is not true. I do not use it in every bulking cycle but I have and I've done so with good success. Winny at the end of a bulker can help solidify gains made as well as give you a bit of an extra push towards the end...a harder push equals more quality muscle IMO. One of my favorite basic bulking cycles has been test/deca/winny.
