Positive Feeling
It's been only 15 days, that i've been using NMN. I have not seen any great improvement yet, but i understand that nothing happens overnight. I am ordering for a 3 months package and would want to give a feedback at least after using it for more than a month. I would like to register that the customer support was excellent. All my queries were clarified promptly and i am very happy that i am buying a genuine product. I will sure come back to give a feedback once i've used NMN sufficiently.
