A few years back I was torn about Proviron being suppressive or not. Information on this is very conflicting and it appeared Proviron much like everything else in the hormonal world was not universal. So being as the timing was right I decided to find out and that was how the Proviron experiment began. I was 20 weeks outside my last cycle. I had originally purchased the proviron to help me bridge from cycle through pct. At 20 weeks ran my pre cycle labs everything was normal for my body. I looked everywhere for the lab work I compiled running this experiment but I am afraid it got thrown out in the years since this experiment was run (my wife would be the culprit of this she hates clutter). So I am just going to fill in what you may need to know. I average 1100 nd/dl naturally so I have high testosterone levels and I also do not have a very high aromatization rate estrogen is always on the low end of normal around 15 pg/ml. My labs also had LH and FSH level over the course of the experiment. I have never encountered a problem recovering so outside of pure curiosity I don’t test them often. Nevertheless those were also normal at the beginning of the experiment.
I ran proviron ONLY for 10 weeks just so I would know if it was suppressive or not and this is what I found.
Week 1-2 25mg 12.5 A.M./P.M. I ran labs. Everything was virtually the same. FSH normal, LH a tiny bit lower but still in ballpark of original, total test slightly lower but same ballpark, but free test a notable bit higher at 10%, estrogen was the same.
Week 3-4 50 mg total split AM/PM Labs
FSH down by about 15%, LH down by 20%, total test down respective 25%, free test back at baseline, estrogen lower by 40%
Week 5-6 75 mg total split three times a day Labs FSH down 50% LH lower by 60% total test down 60%, free test lower by 50% estrogen nearly undetectable.
Week 7-8 100mg total split A.M./P.M. Labs
FSH down 80%, LH, total test, free test all pretty much nonexistent. All three registered on the test with estrogen being the lowest of them all, but based off the numbers I was clinically shut down.
Week 9-10 25mg split 12.5mg AM/PM Week 10 labs
FSH, LH, Total Test, free test, estrogen were all up but none showed an increase more than 10%.
I concluded that it’s dose dependent on how suppressive it is but nevertheless suppressive. It appears that at a dose of 25mg it could help with moods and sex drive during PCT but I believe it would draw out the time one needs to run PCT and perhaps how aggressive the PCT. I base this on the fact that while my labs showed the 25mg dose didnt have a huge effect on an already active HPG, the presence of the same 25 mg dose on a shut down HPG didn’t do much along the lines of rehabilitation. Still this experiment is primitive. Not nearly enough time and not enough variable control for it to be definitive. This is not meant to condone or deter the use of Proviron. This is solely me sharing my experience.
