This is the first time I'm buying a supplement for males only. Btw I'm 39 this year. I don't have ED or PE but I do feel a little bit weak and less energetic these past few weeks.. After buying Vigour, I've been feeling energetic and I'm sleeping very early and waking up on time as well. This product which I'm trying out;I do feel slightly apprehensive about it but to my surprise I do feel as if I'm 10-15 years younger ni kid you not. For all those males out there, whatever ED or PE or weak, please do try NOAH out. And thanks Noah for the discreet package and love box which you gave to me. Have a good day to all. And please irregardless of the products from NOAH I do believe a good diet, sleeping habit and regular exercise keeps one healthy as well.
