I have just purchased a different one and will share how it works, supposedly after a few days of working in the system ( is a daily but can be taken a hour before sex supposedly) I should notice and feel a difference.. I will let you all know as the time goes on as to its effect.
and just so ya know I am one of those weird fellows that things either don't work at all, or I get all the side effects listed ( which are none for this
)
