Product works exactly as described. I've also given it out to a couple of friends . Great results , well priced and recommend for men regardless of age.

Definitely not a game changer. Almost 50 and no improvement, especially in the "SIZE" aspect. Thank God for their excellent return policy. .

Buying again and will continue
When taken daily, noticed an improvement in situations while dealing with erectile dysfunction. So buying for the second time.

I've only taken it 5 time, one of the ingredients apparently didn't agree with me. After 45 - 50 from taking one I felt flush and a little shakey. So I stopped taking them. So I really can't say anything good or bad about this product.
