what is the difference between minoxidil and xandrox?

I noticed at minoxidil.com they had two different versions of minoxidil, was just curious what is the difference. thanks.

Xandrox has 5% alzaeic acid included, which is supposed to block DHT topically. This claim isn't backed by the FDA though.

I'm using Xandrox (5%) as part of my big 5 regimen. I figure it's no worse than regular minoxidil, and I'd like to give my hair every fighting chance.
