Can I Add Dutasteride With My Existing Daily Finasteride?

Doctor Rassman, one last thing if you don’t mind, for someone like me who has been on finasteride for like 4 years with good results, im thinking of adding dutasteride 0.5mg to my regimen every other day, not because I want more hair because im happy with what I have its because I want to destroy dht even more, and who know I might get more benefits who knows. I know eliminating all of dht is not the answer but I just want to. there was a study where a man added dutasteride 0.5mg once a week to a finasteride regimen and got better benefits. is it redundant to take both? to be honest side affects are the least of my worries, as with finasteride I have experienced non at all. even if I dot get sexual side affects I don’t mind as my hair is more important LOL. that’s just me lol. When I asked my doctor he said if I want to get hair greedy to add rogaine, but I don’t like topicals at all and I rather add duatseride, he said no, to only take either finasteride or dutasteride. but he is a regular GP, not a hairloss expert like yourself. I read a lot of forums where people take both as well, not sure. can one medication offset the other if taken together. thank you so much, your awesome.

If every thing is working on finasteride, why risk new side effects by adding dutasteride?
