i wouldnt use winstrol without test or sarms personally but thats up to you.. MAKE SURE you are using n2guard with winstrol as its imperative and mk2866 is always wise to use with winstrol considering the joint pain likely involved with it... it does not convert to estrogen so there are no concerns there but you may also want to look into n2shampoo if you are prone to mpb as we know winstrol is a strong dht and can hurt your hair if you are prone to that
I would absolutely stack with MK2866 and/or MK677 here and as Dylan pointed out, N2Guard is a must with any oral steroid and really should be used on any cycle period
