Money-back guarantees are commonly advertised on product pages in this category. Independent research on closely related products found published refund policies that exclude opened or used items — a direct conflict for a supplement you need to open to evaluate.
Contact HoneyBoost's official customer support directly — not this website — before ordering, and ask them to confirm in writing whether an opened bottle is eligible for a refund under their advertised guarantee. Don't rely on product page language alone.
Keep that written confirmation along with your receipt and order confirmation.
