Short answer: Because ingredients like bacopa are studied over 8 to 12 week periods, judging this product inside a fortnight would not be fair to it or to you.
Why the guarantee clock starts at delivery, not purchase
The guarantee runs 90 days from the day your order arrives — a specific, favorable detail worth noting, since delivery time doesn't eat into your evaluation window.
What the refund process specifically involves
Contact customer support within that window to arrange a return — refunds are processed after the return is received, a specific, direct process.
💡 Worth knowing: guarantee terms are set out in full at checkout — please read them there before ordering.
