WTF!?
Sorry, but this is a PM board fau-pau
You should know that "bulking" and "vascularity" do not go together.
Bulking means you gain weight - which is accomplished mostly by over-eating and training and sleeping -your muscles get larger, your fat gets larger, side effects..everything is more more more
Thats the whole point.
You can worry about vascularity AFTER the bulking
