IMO the winny should be ran for a minimum 6 weeks, preferably 8 though...as far as the AI goes, I personally never use them because I don't get gyno, thankfully but i do keep them on hand...but if you have gyno or get gyno than keep the AI running but i'll let a vet get into more detail on the use of an AI while on winny cuz some people say that it has some of the same benefits as an AI...while on winny you should expect some nice lean gains and strength while dropping some good ol' wasted BF...great shit in my opinion and I use it on EVERY cycle unless I have anavar on hand
keep in mind, winny does dry out your joints and more times than not causes some joint stiffness and pain so don't be alarmed...not sure if that pain is seen while on orals though...another point for a vet to touch on
