Short answer: A 60-day guarantee is advertised. For an under-documented botanical blend, that refund window is the most practically useful part of the offer.
Why the guarantee is framed as unusually important here
It lets you find out on yourself rather than on a promise — a direct, honest framing given the formula's own acknowledged evidence limitations.
What specifically to confirm before ordering
The exact window for requesting a refund, the return address, whether bottles must be unopened, and who pays return postage — specific, named details that decide whether a guarantee is worth anything.
💡 Worth knowing: the specifics are set by the retailer, not by this page — confirm all of it on the checkout page before you order, and keep your order confirmation.
