Due to the sensitive and perishable nature of research chemicals, all sales are final. However, we strive to ensure customer satisfaction:

• Damaged or Incorrect Orders: If your order arrives damaged or incorrect, please contact us within 48 hours of delivery with photos and a detailed explanation.

• Lost Shipments: For lost packages, we will assist in filing claims and offer a resolution on a case-by-case basis.

• Returns: We do not accept returns of any opened, used, or improperly stored products under any circumstances.

• Cancellations: Order cancellations are only possible if the order has not yet been processed or shipped.

For all issues, contact us at: support@sigmaapeptides.com
