I would say Tren and Winny seem to be 2 good products that tend to harden you up a bit and somewhat solidify the gains. A lot of people respond different to different steroids, so while some will say EQ is good for that, it could just do that for them.
EQ does increase vascularity, but if you are not lean, you'll never see it.
Proper diet and proper PCT will solidify your gains in the end.
