erectile dysfunction
"I used sildenafil today, took three 20 mg tablets and it work as good as Viagra. I used Viagra 100 mg for a year and this work great and no side effects, just a little flushing. Took on an empty stomach and worked in 30 mins. Lasted quite awhile. It cost me $73.80 for 30 tablets compared to paying  $261.00 for 10 Viagra with coupon.  A lot cheaper than Viagra work awesome. Thank you"
