The lowest per-bottle price is tied to the largest package here — worth understanding why that pairing genuinely makes sense given this formula's gradual timeline.
The 6-bottle package brings the price down to $49/bottle with free US shipping and the lowest cost per bottle, per the site's own pricing structure.
A 180-day supply covers well beyond the several-week window most user feedback points to — giving genuine room to judge results fairly without running out mid-evaluation.
Backed by a stated 60-day money-back guarantee.
