It was about a year ago when I started noticing my erections were not quite as hard, orgasm control was not as good and libido was lessening. I just chalked it up to stress at the time and altered my exercise and eating but had little effect on the sexual end of things. I had limited improvement with other sexual supplements but decided to give Orexis a shot based on the great reviews. Boy I could not be happier as within a week I noticed a dramatic improvement in firmness, control and libido. I have not had any side effects and I (and my wife) are one happy customer. Thanks for a great product!
