oral Winstrol (winny) halflife = 9 hours
injectable Winstrol (winny) = 24 hours
i think you are speaking of injectable Winstrol (winny), and yes, you should go ED. as well, IMO, you should be taking the prop at 50 mg ED as well...
there are guys that go EOD on prop, but to negate the peaks and valleys of the test i always go ED
