Nervora carries a 60-day money-back guarantee, covering every package including empty bottles, per the official policy.
The guarantee runs for 60 days from purchase and covers dissatisfaction with your results or your overall experience. That window comfortably covers the three-to-six-week period most customers say they need to judge the formula.
Contact the official store directly with your order number, within the 60-day window. Widely reported customer feedback describes the refund process as being honored without difficulty, which is a meaningful signal, but confirm the exact steps with support before you rely on it.
