me personally I wouldnt use two different orals at once as it is harsh on your liver...especially a winny and var combo since they both do the same thing to some extent...so id lose the winny and do the var... what kind of test do you have? 500mg ew is a good starting point...
Not at once, but the var could be ran in the beginning of the cycle and the winny towards the end.. But personally.. I hate winny
Stang, 500mgs a week for a man your size would work just fine..
