The 2-bottle package is worth understanding on its own terms before comparing it to the larger tiers.
The 2-bottle package is $79/bottle for a 60-day supply, totaling $158, with free US shipping included per this formula's own stated policy of free shipping on all packages.
Since this formula's own materials describe daily comfort building gradually over consistent use, a 60-day supply covers only the earliest phase — worth weighing that against your actual evaluation goals before choosing this tier.
