If you really break down what aging is in a nutshell, it's slowing down of cells reproducing. This is why I low dose with HGH and it increases the speed at which cells regernate to youthful levels. Will it actually reverse aging? I think to some degree, yes it does. But not overall. It's not a miracle, but it's the best thing we having going right now outside stem cell stuff that nobody but the richest of the rich can dabble with.
