I started a 5mg/daily dose a couple of weeks ago. I don't know if I can talk about overall health benefits but I will say I have had the strongest and most frequent NRB's in years, and this is not a place I have been lacking. It's awesome, but I will say that the climax itself is about 20% less euphoric than usual. This is the first time I've ever taken anything like this. My wife is enjoying it.
So far my eyes are doing. No lost vision. Though I wouldn't mind if a loss of hearing was a side effect.
