Winstrol & Proviron cycle

Hi guys, sorry again for all the questions. I am wondering why most of the guys I know go on Winstrol and Proviron weeks before a bodybuilding contest and take a PCT afterwards? As far as I know Stanazol does not aromatize and proviron is an anti e. According to my little knowledge a test is the base of all cycles which in this case isn't present, and is a PCT necessary seeing that they use proviron with it? Is this good, can one do this or is this just bad habits?
I have even heard of guys that just use winni just before a contest on it't own, I would really appreciate some feedback just to broaden my knowledge.

Winstrols can be quite supressive in higher doses but even lower doses will cause some degree of shutdown and that all depends on how YOU and how YOUR body reacts to the supression. Proviron will still cause some degree of shut down and should not be used as PCT. All anabolic steriods require PCT, hope you get the point .

If I had to do an oral only cycle (not that I would for obvious reasons), but if I did it would be this cycle. Bulking makes no sense without test but cutting does to me.

Hey bro.. get a PCT done after any cycle!! I was also told that you dont need a pct after winstrol and that clomid and proviron can be used as a pct..so I did it this way, and fucked myself up! Got low test levels now and im trying to get it sorted and its very likely that I got low test from the cycle and from not doing a proper pct!

I would add in some test bro, some prop will be fine! Test should be the foundation yes, whether you want to cut or bulk, test is always important!!
