I'd have to go with Dr. Lee's Xandrox 5% for daytime, and 15% for nightime use. I've been buying through Dr. Lee for about five years now, and I've always been VERY satisfied. Dr. Lee knows his stuff, the shipping is quick, and above all, the products are "top notch". And, the Xandrox is a two-in-one topical treatment - you're getting the Minoxidil plus the DHT blocker. Just my two cents ...
