Since this formula's own stated guarantee is calculated from your purchase date, your order confirmation email is worth keeping accessible from day one.
Your order number, the purchase date, the exact package and price you paid, and any correspondence with customer support — all worth keeping in one place, not just your inbox.
Since this site's own materials note a discrepancy between 60 and 30 capsules per bottle across different sources, your order confirmation is also worth checking for any stated capsule count specific to your purchase.
The 6-bottle bundle carries the lowest displayed per-bottle price and free US shipping.
