cold sores
"Considering pretty much nothing has ever worked for me when it comes to stopping cold sores, this is a life saver. If u catch the cold sore in time this pretty much stops it from getting worse when I take 2 grams and 2 grams 12 hours later, than follow up with 1 gram the next day it's already started healing. The only other thing that's every helped is  lysine and that's more preventative so I don't get it. Once you have it though this is the best stuff by far. It's pricey though so you better have insurance."
