Short answer: Commit to at least 90 days. The formula is cumulative and judging it after ten days tells you nothing — a direct, blunt standard set by the review itself.
Why "cumulative" is the specific, honest word used
This isn't a formula designed for a single noticeable spike — it's built to build gradually, which is exactly why a short trial window genuinely can't judge it fairly.
Why this directly shapes which packages are actually recommended
The 3-bottle and 6-bottle packages align with the 90-day-plus window where most people report their clearest results — a deliberate alignment between the honest timeline and package sizing.
💡 Worth knowing: a 30-day supply rarely gives the formula a fair trial — worth factoring this directly into which package you choose.
