In my opinion, it won't alleviate it. Your best bet is to stop the tren. Winny has a very weak affinity to the, while tren has a very strong affinity. Picture it as a game of tug of war, with the tren having a 300 lb dude on one side and the winny being a 100 lb weakling.
I'd either
a)stop the tren
b)start taking nolvadex (the theory behind that is gyno must be caused by more than 1 source, whether it be igf-1, progesterone, estrogen, prolactin. Tren can raise IGF-1 levels like no other and cause progesterone induced gyno. By eliminating the elevated IGF-1 levels all that's left is progesterone, which isn't strong enough to cause gyno)
