The 6-bottle package carries a specific value worth understanding precisely: the lowest cost per bottle among the three package sizes, plus free shipping.
$49/bottle for a 180-day supply, totaling $294, with free shipping standard on every package — against the $79/bottle price on the smallest 2-bottle package.
Given this site's own materials specifically recommending the 3- or 6-bottle option for the gradual, long-term timeline it describes, a 180-day supply gives genuine room to evaluate fairly without running out mid-evaluation.
