Returns & Refunds Policy

Effective Date: March 22, 2026

Because our products are classified as research-use-only laboratory supplies, we follow strict quality and compliance standards. Please review the guidelines below before placing an order.

Eligibility for Returns

• Returns are accepted only if the product arrives damaged, defective, or incorrect.
• Claims must be submitted within 7 days of delivery with supporting documentation (e.g., photos, order number, description of issue).
• Products must be returned in their original sealed packaging with all labels intact.
• Opened, used, or tampered products cannot be returned due to safety, contamination, and compliance requirements.

Refunds

• Once your return is received, inspected, and approved, refunds will be issued to your original payment method.
• Refund processing typically takes 5–10 business days, depending on your bank or payment provider.
• Shipping costs are non-refundable unless the return is due to an error on our part.
• PeptideArk reserves the right to deny refund requests that do not meet the eligibility criteria above or that show signs of misuse, tampering, or fraud.

Restocking Fee

• Approved returns may be subject to a restocking fee of up to 15% of the product price, at PeptideArk's discretion.
• Restocking fees will not apply if the return is due to a shipping error or defective product caused by PeptideArk.

Exchanges

• Exchanges are available only if the wrong product was shipped by PeptideArk.
• If eligible, a replacement will be shipped at no additional cost.

Non-Returnable Items

• Any product not in its original sealed condition.
• Products returned after 7 days of delivery.
• Products purchased by mistake or without reading compliance disclaimers.
• Products that have been stored improperly by the customer.
• Custom or special-order products.

Chargebacks & Payment Disputes

• If you have an issue with your order, please contact us at peptideark@pm.me before initiating a chargeback or payment dispute with your bank or payment provider.
• Filing a chargeback without first attempting to resolve the issue directly with PeptideArk may result in permanent suspension of your account and inability to place future orders.
• PeptideArk reserves the right to dispute any chargeback and provide evidence of delivery, terms acceptance, and order fulfillment to the payment provider.
• Fraudulent chargebacks (chargebacks filed for products that were received and used) may be referred to collections or pursued through legal action.

Return Shipping Responsibility

• Customers are responsible for return shipping costs unless the return is due to a shipping error or defective product caused by PeptideArk.
• Return shipments must include a tracking number. PeptideArk is not responsible for return packages lost in transit.
• Products must be packaged securely and in compliance with all applicable shipping regulations for research materials.
