var is a good choice for strength.
winny is probably only good for its hardening properties for those with low bodyfat.
to stack the two doesnt make sense.
instead, choose either var or winny, and add an injectable like primo, eq, or deca.
primo/var - killer cycle but pricy!
primo/winny - solid hardening cycle, primo gonna run the price of this cycle up!
deca/winny - good cutting cycle, affordable.
eq/var - solid cycle.
