How Long Does It Take To See A Maximum Benefit? and how much should I take?
Like any supplement, Prelox® needs time to unfold its beneficial actions in the body and to exert its effect on the vascular system by allowing the blood vessels to become more responsive.

How About Taking Prescription Medication?

Prelox® supports the body-own mechanism of nitric oxide and thus restores the natural process leading to an erection. More importantly, during regular supplementation with Prelox® healthy production of nitric oxide is permanently restored. This allows men to indulge in a youthful sex life including spontaneous sexual arousal. Sildenafil inhibits the processes triggered by nitric oxide, thus amplifying the activity of residual nitric oxide produced. If your physician has prescribed sildenafil or an equivalent drug he has done so for treatment of a diagnosed disease. Please consult your physician for treatment options.

Will Prelox® Begin To Work Immediately?
