I had bad experiences with pro hormones and with clomid. I did try a short course of nolva, 10mg/day(tablets not liquid) for about a month, as at the time I was considering doing anabolics and wanted to make sure I would have something for pct that wouldn't make me feel like shit(clomid).
I felt pretty good whilst on nolva, and had more energy, and better recovery from exercise than as a natural bodybuilder in my 40's.
I would try out more than 2mg/day. Start at least 10mg/day. 20mg-40mg is what is usually recommended for pct. I have no idea about long term use and its effects on the liver, rest of your body etc(longterm use of clomid at low doses is supposedly pretty safe, though nolva is obviously a different compound.)
If I hadn't eventally tried anabolic doses of testosterone( which I am mid way through a cycle and really liking so far) I was going to try one month on, and one month off with nolva, and adjust from there depending on how I felt.
Definitely don't rely solely on my advice I am no expert, just letting you know my personal thinking and experiences.
