Using only the page's prices and supply labels, the 6-bottle bundle at $294 works out to about $1.63 a day if each bottle is a 30-day supply, and the 2-bottle package at $158 plus shipping to about $2.63 before shipping. That is our arithmetic, not a figure from the seller.

Whether the label shows the amounts per ingredient, whether the refund terms are clear and whether you will log honestly for 60 days. A product with an easy refund and a clear log costs less to test than the sticker price suggests.
