At PeptidoGlow™, we carefully prepare and ship all orders using USPS Priority Mail or a comparable priority service. Shipments include carrier insurance, subject to the carrier’s terms and coverage limits.

Because our products are sensitive research materials, all sales are final. We do not accept returns, exchanges, cancellations, or refunds once an order has been placed.

Please review your product selection and shipping address carefully before checkout. PeptidoGlow™ is not responsible for incorrect addresses, carrier delays, lost or stolen packages, refused deliveries, or packages marked as delivered.

If a shipping issue occurs, please contact the carrier directly using your tracking number. For USPS shipments, this may include a Missing Mail Search or insurance claim. When sender assistance is required, please contact PeptidoGlow™.

Delivery dates are estimates and may be affected by weather, holidays, customs, service interruptions, or other events outside our control.

By placing an order, you agree to this policy, except where prohibited by applicable law.
