If I have the goal of gaining lean muscle, and loosing bf%, which would be more effective. I am thinking fina/winny only since there will be no estrogen conversion and the lack of test will make it much easier to keep the mass lean. Since there wouldn't be any test in there to cause water retention it would also be better for not getting bloats.
I'm wondering from the fina vets on here on this... where's OG at?
