This site's own materials mention timelines in a few different places — worth reconciling them into one honest, week-by-week picture.
Weeks 1-2 are about building the daily habit. Weeks 3-6 bring gradual stamina support. Week 6 and beyond is where sustained daily support is expected to continue — three distinct stages, not one single number.
Judging the formula at week two means judging it before the brand's own timeline expects any stamina-specific change — worth using the full six-week-plus window, which conveniently matches the 60-day guarantee.
