I think you're going about it the right way Greg. My advice would be to start on something like 0.25mg or 0.5mg, two or three times per week. Then maybe every one to two months, very gradually up it, assuming no sides are evident.
Personally, I started out 4 years ago on 1.25mg daily. Looking back, I would have started on something along the lines of what I suggested to you. For two years I didn't notice a thing, but then I started noticing sides. This could very well have had something to do with another drug I was on for my skin - Roaccutane. Either way, since then I have changed my dose to 1.25mg every MWF, then to 0.5mg daily 5 months ago......and now I'm thinking of coming off it for a while just to give my body a rest from it. Thinking of going on Nettle Root for a bit to still keep some anti-DHT stuff in my system.
