Modafinil remains one of the greatest productivity supplements you can take. On Modafinil, you experience nothing short of pure action and raw productivity where tasks and projects magically complete themselves. Modafinil has become a staple for entrepreneurs and anybody required to work long hours. As a normal human, working long hours completely drains you mentally and physically. As a human on Modafinil, you demand even more work load.
