I agree, if you are running test and tren, then don't waste your winny.
I love doing 6 week winny only cycles. Save it for a 6 week winny only cycle at 50 ED. Just my .02.
you will do fine with that dose, winny has great synergy with T due to its SHBG lowering effects, so it can be run quite low when it is run in a stack with other things. this also reduces the risk of winny sides to the joints especially
