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 90-to-180-day evaluation timeline

Since fuller results are described as building over 90 to 180 days, having your purchase date clearly documented protects you if there's ever a question about your remaining time within the 60-day guarantee window.
