Customer Questions & Answers

What is SIZE and how does it work?

SIZE is designed to support the blood flow to the penile “spongy” tissues during an erection. Over a period of time, SIZE helps the tissues to hold and contain more blood causing a fuller and firmer erection.*

How long does it take to work and how long will it last?

The product may be taken a variety of ways. Some men prefer to take it daily, one pill in the morning and one pill in the late afternoon or early evening. Others prefer to take two pills 45 minutes to an hour before intimate activity. Both regimens will work if it is taken daily. The herbal effects last between four and six hours.

Is SIZE safe to use if I have a medical condition?

We recommend that anyone with medical questions or concerns consult their doctor before taking any of our products.
