It makes you produce more sperm. Good product...

I've tried several multivitamins and this one delivers everything it says. I have more energy and have been able to exercise and stop taking blood pressure medicine.

After taking these vitamins, I saw a difference, not only in my daily routines but also, in bed. As I'm getting older, every day a part of my body hurts. But these vitamins are making a difference.

Unfortunately, it gets a one star for containing Titanium Oxide, a cancer causing chemical. It’s only purpose is to make the pill white. I’ll go to a healthy store from now on.

Why is this product unavailable. I have been taking it for over 2 decades, and now I have to look at other vitamin packs. Don't mess with success. It's a great product and works very well.

First the pack came on time, GNC is complete medication. Take it with food and keep drinking fluid. I feel a lot of energy and strength. I will buy GNC again.

So far it's OK. Lot of pills, but I'm OK with it. I just wish she was more cheaper, but I've been taking it for two weeks now, and I can tell I with more energy.

These vitamin combo packs are having a good impact on me. I have only been taking them a little over a week but i am feeling more energy as well as other nice effects! I am reordering now:)

I have been taking Performance & Vitality vitamins when the Vitapak was introduced. I tried a cheaper brand but it was not the same. I have recommended it to others in my family. They love it.
