To answer your question, for every day use, xandrox would be better. But for the type of hairloss you are having, you will need to get the xandrox 12.5% probably b/c 5% hasn't been shown to have much affect on the temporal areas. The 12.5% has the a. acid in the same dose as the 5%, but it is 12.5% minoxidil. The reason for this is b/c minoxidil works in a dose-related manner and it's gonna take more to work on the stubborn, temporal areas.
Now, if you are wondering which to use during a cycle, I'd tell you to use both of them.
