I research many of the dating products out there and recently landed on a forum called "The Attraction Forum". Wow, is all I can say. There are guys there of all ages giving excellent advice and support. The product in my opinion are very realistic and I wish all men would put forth the effort that these guys do to up their dating game.
This isn't like the Don Juan group that seems to promote downgrading women. These guys know their stuff and teach guys how to approach, meet, and keep women. The forum is free and packed with useful information.
The best seller is an e-book called Magic Bullets. It's the basics and well worth the investment especially to those nice guys who get caught in the friend zone.
