are you sure? where did you hear that, I've never heard that winny can prevent gyno, do you mean nolvadex or proviron.
if I'm missing something, by all means fill me in bros.
BTW, using drol and winny might be abit too much for your liver to handle, cos they're both C-17aa compounds. pointless doing 4 weeks drol, will mainly be water bloat, would be better to do:
wks1-3 drol 50mg/ED kickstart cycle
wks1-8 sus 250mg or 500mg/wk
this will get you nice gains, dont forget anti-e's like proviron and nolvadex in case of gyno. then a nice post cycle therapy should maximise keeping those gains.
peace
