What I get from it: I'm very vascular naturally but proviron makes my veins sticks out a bit more. Not as much as compounds like EQ or Masteron but it's very noticeable.
Libido : My libido is through the roof on proviron, it may be a problem for some but my GF is fine with that :)
Side effects : prostate hypertrophy. I've had symptoms in the past but now I use saw palmetto and it works as the symptoms went away pretty fast.
Proviron may increase blood pressure a bit but not by much
Dosages: I've used it at 50mg/day, in the morning with good success.
I tried dosages ranging from 30-200mg per day and I'd say the sweet spot is in between 50-100mg per day.
There isn't many benefits to go over 150mg/day as you mostly only get high blood pressure symptoms from the increased dosage, in my experience.
