Eu Natural tip
You don't need to finish or even open the bottles to get a refund within the window - Eu Natural explicitly accepts empty bottles back, which is unusually generous for a supplement brand.
Prolon Life tip
Damaged box or missing items are handled separately from returns — photograph the problem and contact support within 14 days, since that's the only path to a refund or replacement once your order ships.
