Within the first days... If not from Day 1
As you heard from the guys who have given video feedback about their Aphro-D experience, the libido and confidence effects are same-day. You will notice a jump in your sex drive, sexual energy as well as overall self-confidence in the first few days (and this will continue day after day, week after week).
It is also common to have more restful sleep (and feel the benefits night after night).
You will have a significant improvement in erection quality when you have sexual intercourse or when you masturbate. You will notice a significant enhancement in your morning wood as well.
