nice to meet ya. my name is david. i've been a pharmacist for 44 years. when i have customers come in and ask for something for memory, i recommend prevagen. number one, because it's safe and effective. does not require a prescription. and i've been taking it quite a while myself and i know it works. and i love it when the customers come back in and tell me, "david, that really works so good for me." makes my day. prevagen. at stores everywhere without a prescription.
