Oh, I see i quoted the wrong paragraph from that paper, my bad, fixed it. Not sure about time. I haven't researched this... but my guess is testosterone is highest in the morning, so DHT levels as well, and therefore you suppress most taking it in the morning? It'll probably insignificant anyway, it's more important to be consistent with the time. So a time which you are sure you are able to take finasteride. E.g. morning might be a problem to do consistent in the morning if you are into partying
