Bests & Worsts Reviews from Amazon

i have taken L-lysine for over 20 years to keep fever blisters from flaring on my chin. I have used many (usually walmart) brands during that time and have always had success with preventing or stopping them from forming. I took your product for several weeks and noticed a fever blister trying to flare, so added extra to my regimen of your product. It did not stop them from flaring. So...i went to walmart and bought some l-lysine, stopped yours, and started taking the walmart brand. within two days, the flare was gone. I don't know what's in your product, and believe me I'm PROAmerican product...but it's not lysine.
