Winny can help as a mild AI but should not be used in place of one...Winny does help to cut on a cycle, partially due to it's "drying" effects on your body...but with the drying of your joints comes stiffness and irritation...plus it does help to add a very minimal amount of size compared to other steroids...
do i run winny through every cycle? no but i do run winny or var through almost every one...
