Since this formula's own guarantee is calculated from your purchase date, and this site's own research already flags a timing gap on the smallest package, your order confirmation email is worth keeping accessible from day one.
Your order number, the purchase date, the exact bundle 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 research shows the 60-day guarantee can expire before the brand's own 90-to-180-day results window on smaller packages, having your purchase date clearly documented protects you if there's ever a question about timing.
Backed by the brand's stated 60-day money-back guarantee.
