Same John Lee tablet, twice the strength on each unit: 400 mg of acyclovir, supplied as a blister of five. Where the thirty-count box is built for a longer run, this is a compact strip rather than a full carton.
The compound works by interfering with viral DNA replication once the virus has entered a cell, so it is aimed at active outbreaks and does nothing for an ordinary bacterial infection. John Lee presses it as a simple oral tablet with no coating or modified release.
