Your Order Confirmation Email: What to Actually Save

Since this formula's own guarantee is calculated from your purchase date, your order confirmation email is worth keeping accessible from day one.

What to actually save

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.

Why this matters given the three-to-six-week evaluation window

Since results are described as most commonly reported at three to six weeks, having your purchase date clearly documented protects you across the full 60-day guarantee window this formula's own materials describe.
