There's some interesting research on Proviron (mesterolone) that the guys over at Ergolog have earthed up.
It seems that Schering did a fair bit of research on the various esters of Proviron back in the 1970 and 1980s.
At higher oral doses (50mg or more per day), Proviron was equally or slightly more effective than the best typical tricyclic antidepressants of the day (this was before SSRIs had really entered the market), but without the side-effects.
At lower doses (1-20mg) Proviron was an effective psychostimulant, and that effect kicked in within 2-3 hours.
Doses of up to 450mg/day were tested and shown to be safe with very little effect on endogenous testosterone synthesis, although maximal effect was achieved at much lower doses.
You can have a look at Ergolog's article here and link through to the research papers from there.
