I wrote a review of PUA's
here and
here.
There is good information to help get better with women in small doses but you need to sift through the tons of garbage first. If you are inexperienced with women or unsatisfied it will be very difficult to discern the good from the bad. Most people who get into PUA stuff are desperate for change and just automatically adopt all of the beliefs. Most are less than healthy like "all women are biologically programmed to cheat" or that you can never ever show interest in the woman.
