How to read it
The peak arrives roughly an hour to ninety minutes in and holds for an hour or two, that window is as good as it gets, and chasing it with more only adds jaw tension, heat and a heavier crash. If you are going to take a booster at all, the one defensible moment is early in the peak at about half your first dose; there is more on that in the dose calculator and the full dosing guide.
