To your question. As far as i know, IF people experience side effects, they get them with oral as well as with topical finasteride. So yes, i guess it would be same as taking oral finasteride and oral dutasteride.
I wouldn't call it a "no-go area" for us dutasteride. users, but I do wonder why you're considering the 'Plus' version of Xandrox 15 over the standard one.
