Returns & Replacements
If your order is not delivered, arrives damaged, or is the wrong item, you're eligible for a full refund or a free replacement. For all other cases, sales are final due to the nature of research materials.
Order undelivered, damaged, or wrong? We'll make it right with a refund or replacement — email us within 7 days of delivery.
Returns
No Physical Returns
Because these are research materials, PepChain cannot accept the physical return of delivered product, and orders are otherwise final. However — if your order is not delivered, arrives damaged, or is the wrong item, you are eligible for a full refund or a free replacement. See the sections below.
Damaged, Wrong, or Undelivered
Refund or Replacement Eligibility
If your order is not delivered, arrives damaged, or is the wrong item, you are eligible for a full refund OR a free replacement — your choice. To qualify, contact us within 7 days of delivery (or of the expected delivery date, for a non-delivery) with your order number and, for damaged or incorrect items, photographic evidence of the issue.
How to Request
Replacement Request Process
Email us at [email protected] with the subject line "Replacement Request — Order #[your order number]" and include the required documentation. We will review your request and respond within 2 business days.
Refunds
How Refunds Are Issued
Once an eligible issue is confirmed, your full refund is returned to your original payment method — typically within 5–10 business days, depending on your bank or provider. Prefer a replacement instead? We'll ship one free of charge. Refunds and replacements apply only to undelivered, damaged, or incorrect orders; for anything else (such as a change of mind or an opened product), sales are final due to the nature of research materials.
