Only if you want to strain the hell out of your liver!
I don't want to sound smug about but using both at the sametime, what are you wanting to achieve? You may consider using Dbol then following up with some Winny and then finally topping it off with about 14 days of clomid to snap the system back into shape. In order to keep the gains made.
sounds like a good cycle to me..like mustang said..use your milk thistle and dont' get hammerd on the weekends...i remember in the middle of my winny cycle that i drank like a bear, in the middle of the night i felt like my liver was being stabbed 100 times...Not too good..never drank during cycle again
