Lysine....   L-Lysine...   same, same.  This is very popular and also quite 
effective for many people who are trying to control cold sores / fever 
blisters (as well as for controlling herpes outbreaks).  Its typically found 
in either 500mg or 1000mg doses and because its an amino acid, its normally 
very safe for most people to use.
