I agree with you that it's def not hype I have been running letro on a npp 150 EOD and test e 185 eod cycle for a bad gyno flare up because I tried using adex for my ai granted my doses of letro were high at a day I added proviron with in 48 hours I crashed my estrogen hard my lips were dry cracked headach my crazy libido that I had on just the letro was gone I was exausted . This was after running the letro for close to a month at that dose. I usually run letro on cycle at EOD if test is over five hundred and that keeps me between 30-60 so I'm used to letro. I know that provi is different than masteron, but I think they are similar enough that one one can make a comperison I have limited experience with it. but my estrogen was stable and I felt great energy sex drive , u know when u just feel dialed in. 4 doses of 25 mg of proviron spaced 12 hours apart approx. And I felt like a total estrogen crash. Joints got even crunchier. This was my first time using provi and I was really looking forward to the free test benefits, but I may have to try it another time. I have never gotten bloods while I was on nandrolone(DECA/npp), and I heard they can alter skew bloods can someone elaborate, or tell me a blood testing lab that does not have this issue. I would like to dial in estro with the provi if possible.
