Women can take DHEA. At large doses, however, it will cause virilization.....so go easy. I believe that the common recommended dosage for women is 50mg/day....maybe someone like Dr.D can let me know if this is correct.
Now....if you are looking for libido boosting.....absolutely nothing beats 1-T/4AD transdermal. 4AD especially. You have to run it low because of virilizing (like 20mg per day or less YMMV). I can personally attest to several women who seem in much better moods, even mentally sharper and definitely hornier while using this.
