WOW! I have been using Orexis for only 2 weeks and I feel, and am functioning, like I was in my 20's again. I am 65 and have tried over a dozen across the counter and 2 different pills prescribed by my doctor but nothing has worked like this. In fact some didn't work at all and others made it hard to breath and gave me a headache. No side effects for me with this product! Wish I would have found this 5 years ago when my sex life started to go South. I'm ordering ! my next batch today and will not be with out them again!
