The tonic makes your body produce the “erection enzyme” that relaxes the muscles in your penis and boosts the nitric oxide that allows your penis to be filled with blood. That way rock hard erections can happen when you want them, and for as long as you need them, you will never have to wait again for blue pills to "kick in" or fear if you will be ready or not. Not only that, but the mix basically retrains your penis into getting natural erections once again.
