My story is similar to another reviewer (Peter).
I gave this product a full four months and took it religiously every day, and it did ABSOLUTELY NOTHING! I too tried calling for a refund and got the one-month story. I even offered to return two bottles because I bought a six-month supply because I also fell for the Shark Tank story and they gave testimonials from Tom Hanks and Sylvester Stallone. These guys must have made their claims because they are getting a piece of our money as this product is a bunch of BS. Rejuvalex says it works on 90% of people. I'm still looking for a positive review other than their website that says this product works.
I've noticed the Shark Tank and celebrity comments are no longer part of their site. We all got scammed, and it's sad people are willing to take advantage of others like this! Karma!
Bottom Line: No, I would not recommend this to a friend
