Short answer: The 6-bottle bundle has the lowest per-bottle cost, but it locks you into a 180-day supply when the guarantee only covers 60 days — a direct, specific mismatch worth understanding.
Why this mismatch is worth doing the math on yourself
A 180-day supply purchased upfront still only carries a 60-day return window — meaning roughly two-thirds of your supply falls outside any refund eligibility if you order the largest tier first.
Why this directly shapes the site's own package recommendation
For a first order, the 3-bottle package is the more sensible starting point — a direct, practical recommendation flowing straight from this disclosed mismatch.
💡 Worth knowing: you can always reorder the 6-bottle bundle once you know it works for you — worth considering this two-step approach instead.
