I've been on Avodart .5 mg per day for about 5 months and can't say that I've seen any improvement. But, as has been said, it can take quite a while to see results. In fact both dutasteride and finasteride can, in some cases, even cause an initial increase in shedding. I can't say about a max dose of Test but, I can report that I bumped my total T level from 258 to 689 after 2 weeks of 4-AD-EC (single dose per day) plus Arimidex (.5mg 3x per week) and my DHT which was down to 6 from the Avodart stayed at 6.
