Pepvian Returns Policy

Refund and Returns Policy

This policy explains how Pepvian handles cancellations, returns, damaged or incorrect shipments, nonconforming products, and refunds for research-use materials.

Last updated: September 7, 2026

Research Use Only

Pepvian products are intended exclusively for legitimate laboratory and research purposes and are not for human or veterinary use or consumption. Products must be handled, stored, and evaluated in an appropriate research or laboratory context.

Order Cancellations Before Shipment

Customers may request cancellation of an order that has not yet entered fulfillment or shipped. Pepvian will make reasonable efforts to honor cancellation requests, but cancellation cannot be guaranteed once fulfillment has begun.

If Pepvian cancels an unshipped order because inventory is unavailable, the order cannot be fulfilled lawfully, a shipping delay is not accepted by the customer, or another material issue prevents fulfillment, amounts collected for the canceled merchandise will be refunded as required by applicable law and the original payment method’s processing rules.

Returns of Research Materials

Because research materials cannot be reliably restocked once they leave Pepvian’s controlled custody, sales of research materials are final after shipment except for damaged, incorrect, missing, or verified nonconforming products, or where otherwise required by law.

If Pepvian authorizes a return under one of these exceptions, the customer must obtain return authorization before sending any product back. Unauthorized returns may not be accepted or refunded.

Non-Returnable Products

Unless required by law or approved by Pepvian because of an error, defect, or documented nonconformity, products are non-returnable after shipment, including products that have been opened, used, altered, relabeled, improperly stored, exposed to uncontrolled conditions, damaged after delivery, or otherwise cannot be verified as suitable for resale or restocking.

Damaged, Missing, or Incorrect Shipments

If an order arrives materially damaged, contains the wrong item, or is missing an item, the customer should contact Pepvian through the support method identified on the website and provide the order number and relevant details. Pepvian may request photographs of the product, shipping carton, labels, seals, packing materials, or other reasonable documentation needed to investigate the claim.

Depending on the circumstances and available inventory, resolution may include replacement, reshipment, credit, or refund.

Product Identity, Quantity, or Analytical Nonconformity

Qualifying concerns involving purity, identity, labeled quantity, heavy-metal limits, fentanyl screening, sterility, or endotoxin levels are reviewed under Pepvian’s Product Quality Guarantee. Purity must meet the applicable ≥99.0% standard, and labeled quantity must meet the applicable ≥95% standard, as further described in the published guarantee.

A qualifying claim may require the original independent laboratory report, applicable Pepvian order information, the specific product and identifiable lot number, an appropriate recognized analytical methodology, and other documentation reasonably needed to verify sample identity and the analytical result.

If a claim qualifies under the Product Quality Guarantee, the customer may choose a refund, store credit, or replacement for the affected product, subject to the terms of that guarantee.

Lot-Specific Documentation

Any analytical or quality information relied upon for a claim must be tied to the specific applicable lot when lot-specific documentation is represented. Generic assumptions about purity, identity, concentration, or analytical performance are not sufficient by themselves to establish a product claim.

Refund Method

Approved refunds are generally issued to the original form of payment unless another method is required by law or agreed to by Pepvian and the customer. After Pepvian submits a refund, additional processing time may be imposed by the customer’s bank, card issuer, or payment provider.

Shipping Charges

Whether original or return shipping charges are refundable depends on the reason for the return, whether Pepvian made a fulfillment error, and applicable law. Pepvian may provide a prepaid return method when a return is authorized because of an incorrect, damaged, or verified nonconforming shipment.

Refused or Undeliverable Packages

Packages returned because of an incomplete or incorrect address, refusal, failure to accept delivery, or other customer-caused delivery issue may be subject to review before any reshipment, credit, or refund is issued. Any permitted deduction for shipping or handling will be applied only when lawful and appropriate to the circumstances.

Backorders and Shipping Delays

Refunds for canceled backorders or unshipped delayed merchandise are handled in accordance with Pepvian’s Shipping & Backorder Policy and applicable law.

Abuse, Fraud, and Policy Misuse

Pepvian may deny a return, replacement, or refund request when there is evidence of fraud, tampering, misuse, false documentation, repeated abusive claims, or conduct inconsistent with legitimate research purchasing, subject to applicable law.

How to Request Review

Use the support method identified on the Pepvian website and provide the order number, product name, lot number when applicable, the reason for the request, and any supporting photographs or documentation. Do not ship a product back until Pepvian provides return instructions or authorization.

Chargebacks & Payment Disputes

If there is a problem with your order, shipment, payment, product, or refund, please contact Pepvian at hello@pepvian.com before initiating a chargeback or payment dispute. We want the opportunity to investigate the issue and resolve legitimate concerns directly, including replacement, reshipment, cancellation, or refund when warranted under the applicable Pepvian policy.

Unauthorized or potentially fraudulent transactions will be investigated promptly. Customers who believe a transaction was unauthorized should contact Pepvian so we can investigate and resolve the issue.

Pepvian investigates and responds to chargebacks and payment disputes. When we believe a dispute is invalid, inaccurate, abusive, or inconsistent with the transaction records, we will contest the dispute and provide relevant evidence to the payment processor, acquiring bank, card issuer, or other financial institution.

Evidence submitted in response to a dispute may include the order record, payment information, account information, IP or transaction data available to Pepvian, shipping and tracking records, carrier delivery confirmation, customer communications, applicable policies, Research Use Only and purchaser acknowledgments accepted during checkout, and other records relevant to the transaction.

A chargeback filed for an order that was properly fulfilled, delivered as addressed, and otherwise handled in accordance with the applicable Pepvian policies will be investigated and may be contested with the available supporting documentation.

Customers who initiate fraudulent, abusive, or repeated unwarranted payment disputes may have their Pepvian account restricted or closed, and Pepvian may decline future transactions from the customer, account, address, or payment method to the extent permitted by law.

Nothing in this policy limits any rights a customer may have under applicable law or applicable card-network rules.

Policy Updates

Pepvian may update this policy as its product catalog, fulfillment procedures, quality processes, or legal obligations change. The policy applicable to an order will generally be the version in effect at the time of purchase unless applicable law requires otherwise.
