First you can not make a cycle of Winstrol only, Every cycle should have some type of Testosterone
Second, Winstrol is the worst steroid you can ever try to cycle alone
Third, Winstrol is a contest Preparation steroid, if you will not compete its very little benefit of using it
Fourth, If you will cycle Winstrol only than you will only gain a small amount of muscle so it doesnt matter that much if you lose it keep it.
Fifth, Winstrol dry the joints and make you prone to injury + fuck up liver and cholestrol levels.
My advice , More research and listen and fallow basics.
Wish you good day and success with your cycle
