PressurePrep is intended to become part of the preparation process—not something you try for the first time on exam day.
Starting 12 weeks ahead lets you use the formula consistently throughout the preparation period and continue through the event itself. PressurePrep ships as a 30-day supply that renews automatically, so your subscription carries you through the full protocol.
The 12-week protocol is a recommended preparation period. It does not mean that the finished formula has been clinically proven to produce a particular result after exactly 12 weeks.
