Well everything from checkout, payment, and shipping (3 weeks time total) went smooth per usual. Now as for the product, I always like to take half of whatever I order (personalized medicine reasons) and it worked right away. It almost felt as if I were a teenager and again I was surprised because I only took half of the dose (10 mg). The pills were small and easy to swallow. I want to say it worked in about an hour and I was able to achieve erections great hard erections for about 3 days, which is what is expected. I didn't experience any headaches or heartburn or other side effects. It was a smooth experiences. Order and rest assured that you'll be getting your moneys worth.
