Tadalafil is a treatment given to men with sexual function problems like impotence or erectile dysfunction. It works by increasing blood flow to the penis for a man to get and keep an erection.  Cialis is like other common sexual performance pills, but the main advantage of Cialis is that its half-life lasts about 17.5 hours. It also has the advantage to reduce side effects and food does not affect its absorption.

When used as a pre-workout, the increased blood flow allows the user effectively have more energy and get more extra pumps.
