why do we start winstrol 5 weeks later than the test?
Winny is more lean and keepable gains, and also mostly used for cutting and to bring out deffinition and striations if you are lean enough. So you would start with test for the main bulking....and add the winny for the finishing touches....it would add more deffinition at the end and mabey help keep the gains better.
Also you can't run winny asl long as test...so if you had to choose between adding winny at the beggining or end of the cycle....it just makes more sense at the end for the reasons I already mentioned!
