RETURN S, CANCELLATIONS, REFUNDS, AND CLAIMS POLICY
Paramount Peptides
Effective Date: July 24, 2026
1. Scope of This Policy
This Policy applies to purchases made directly through Paramount Peptides.
For purposes of this Policy:
- Research Products include peptide vials, peptide blends, oral research formulations, topical research formulations, and other products sold for laboratory research.
- Non-Research Merchandise includes apparel, accessories, and other merchandise that is not a laboratory research product.
Research Products are intended exclusively for in vitro laboratory research. They are not offered or intended for human or veterinary use, consumption, administration, or any form of bodily introduction.
By placing an order, you acknowledge that you have reviewed and accepted this Policy and our Terms and Conditions.
2. All Sales Are Final
Research Products
Due to chain-of-custody, storage, contamination, tampering, and product-integrity concerns, Research Products cannot be returned to inventory or resold after shipment.
All sales of Research Products are final once shipped, except for verified claims expressly covered by this Policy or where otherwise required by applicable law.
Non-Research Merchandise
Apparel, accessories, and other Non-Research Merchandise are final sale unless a different return policy is expressly stated on the applicable product page.
Claims may still be submitted if Non-Research Merchandise arrives damaged or if Paramount Peptides sends the wrong item.
3. Inspection Upon Delivery
Customers must inspect the package, shipping label, exterior packaging, product labels, product seals, and complete contents immediately upon delivery.
Customers should document the condition and contents of the package before discarding any packaging or opening individual products.
Failure to inspect the shipment and submit a complete claim within the applicable deadline may result in denial of the claim, except where otherwise required by law.
For purposes of this Policy, carrier-confirmed delivery means the delivery date and time recorded in the shipping carrier’s tracking system.
4. Order Changes and Cancellations
Customers may request an order change or cancellation before the order has shipped.
An order is considered shipped when it has been physically transferred to and accepted by the shipping carrier. Creation of a shipping label alone does not necessarily mean the order has shipped.
To request a change or cancellation, contact:
Email: support@paramountpeptides.com
Subject: “CANCELLATION – Order #[Order Number]”
We will make reasonable efforts to accommodate requests received before shipment. However, changes or cancellations cannot be guaranteed once an order has entered processing.
If a cancellation is completed before shipment, the amount paid for the cancelled order or cancelled items will be refunded to the original payment method.
Once an order has been transferred to the carrier, it can no longer be changed or cancelled.
Paramount Peptides may cancel an unshipped order due to product unavailability, verification issues, pricing or listing errors, suspected fraud, suspected misuse, failure to satisfy purchaser requirements, or other legitimate business or compliance concerns. If Paramount Peptides cancels an unshipped order, the amount paid for the cancelled item or order will be refunded.
5. Delayed or Unshipped Orders
Paramount Peptides makes reasonable efforts to process and ship orders within the timeframe stated in our Shipping Policy or during checkout.
If we determine that an order cannot be shipped within the promised timeframe, we will provide the customer with the option to:
- Consent to a revised shipping timeframe; or
- Cancel the affected item or order and receive a prompt refund.
If Paramount Peptides cannot fulfill an order, the affected item or order will be cancelled and refunded.
Nothing in this Policy limits any cancellation or refund right provided under applicable law.
6. Qualifying Claims
Submitting a claim does not establish that the claim is valid or that the customer is entitled to a refund or replacement.
Paramount Peptides will review timely and properly documented claims involving the following circumstances:
A. Shipping Damage
A claim may be submitted when an item arrives physically damaged during transit.
The claim must be submitted within 48 hours after carrier-confirmed delivery.
The claim must include:
- Order number
- Clear photographs of the damaged item
- Clear photographs of the exterior and interior packaging
- Photograph of the shipping label
- Photograph showing the complete contents of the package
- Photograph showing the product label and lot number
- Detailed description of the damage
The customer must retain the damaged item and all original packaging until Paramount Peptides completes its review.
Damage caused after delivery, delayed package retrieval, improper handling, or improper storage does not qualify as shipping damage.
B. Wrong Item Received
A claim may be submitted when the item received does not match the item listed in the order confirmation.
The claim must be submitted within 48 hours after carrier-confirmed delivery.
The claim must include:
- Order number
- Photograph of the item received
- Photograph showing the complete product label
- Photograph of the shipping label
- Photograph showing the complete contents of the package
- Description of the item ordered and the item received
The product must remain unopened, unused, unaltered, and in its original condition. Opening, reconstituting, using, transferring, or altering an incorrectly received product may disqualify the claim.
C. Missing Items
A claim may be submitted when one or more items listed in the order confirmation are missing from the delivered package.
The claim must be submitted within 48 hours of carrier-confirmed delivery.
The claim must include:
- Order number
- Photograph showing all items received
- Photograph of the exterior and interior packaging
- Photograph of the shipping label
- Photograph of the packing slip, if included
- List of the items claimed to be missing
- Any additional photographs, video, or documentation reasonably requested by Paramount Peptides
Paramount Peptides may review fulfillment records, package weight, inventory records, packing documentation, warehouse records, and carrier information when investigating a missing-item claim.
A discrepancy between a customer’s statement and the company’s fulfillment or carrier records may require additional investigation and does not automatically establish that an item was omitted.
D. Material Product Nonconformity
A claim may be submitted if a product appears materially inconsistent with its label, published product description, lot information, or applicable published specifications at the time of shipment.
The claim must be submitted within five calendar days after carrier-confirmed delivery.
The claim must include:
- Order number
- Product name
- Lot or batch number
- Clear photographs of the product, container, seal, and complete label
- Detailed description of the alleged nonconformity
- Relevant supporting documentation or analytical information, when applicable
- Any additional information reasonably requested by Paramount Peptides
Claims based on expected results, effectiveness, experimental outcomes, or suitability for a particular research application are not claims of material nonconformity.
A product must not be reconstituted, used, transferred, altered, or improperly stored while a claim is under review. Paramount Peptides may deny a claim if the product’s condition, identity, storage history, or chain of custody cannot be reasonably verified.
If independent analytical results are submitted, Paramount Peptides may require the testing laboratory, testing method, sample-handling information, chain-of-custody records, and complete unedited test report before considering the results.
7. Delayed, Lost, or Missing Packages
If tracking has not updated for at least seven calendar days, or if the carrier confirms that a package has been lost, contact support@paramountpeptides.com with the order number and tracking information.
Paramount Peptides may require the carrier to complete an investigation before offering a resolution.
A carrier delay, tracking delay, weather event, service interruption, or other circumstance outside Paramount Peptides’ reasonable control does not automatically qualify an order for a refund or replacement.
If tracking shows that a package was delivered but it cannot be located, the customer must:
- Check the delivery location and surrounding areas.
- Confirm the shipping address on the order.
- Ask household members, neighbors, front-desk personnel, or building management.
- Contact the carrier for delivery details.
- Notify Paramount Peptides within 24 hours of the carrier-confirmed delivery time.
Paramount Peptides may require a completed carrier investigation, signed declaration, proof of identity, police report, or other reasonable documentation.
A package marked as delivered by the carrier does not automatically qualify for a refund or replacement. Claims involving suspected theft, freight forwarders, mailrooms, shared receiving areas, reshipping services, or third-party receiving locations will be evaluated using the available evidence.
8. Incorrect or Incomplete Addresses
Customers are solely responsible for providing a complete and accurate shipping address.
Paramount Peptides is not responsible for delays, failed deliveries, losses, or returns caused by incorrect, incomplete, outdated, or undeliverable address information provided by the customer.
If an address correction is requested before shipment, we will make reasonable efforts to update the order. Corrections cannot be guaranteed once the order has been shipped.
Orders that have shipped cannot be redirected or cancelled by Paramount Peptides.
Refunds and complimentary replacements will not be provided when a delivery problem results from customer-provided address information, refusal of delivery, failure to collect a package, or an unauthorized forwarding arrangement, except where otherwise required by law.
9. Non-Refundable Situations
Unless otherwise required by applicable law, refunds or replacements will not be provided for:
- Change of mind or buyer’s remorse
- Claims submitted after the applicable deadline
- Research Products returned without written authorization
- Products that have been opened, reconstituted, used, transferred, altered, or improperly stored
- Product seals broken after an issue could reasonably have been identified
- Claims based on expected results, effectiveness, experimental outcomes, or suitability for a particular research application
- Normal differences in appearance that do not establish material nonconformity
- Damage occurring after carrier-confirmed delivery
- Failure to retrieve or inspect a package promptly after delivery
- Failure to follow storage instructions on the product label or accompanying documentation
- Delivery problems caused by an incorrect, incomplete, or outdated address supplied by the customer
- Refused or abandoned deliveries
- Unauthorized resale, transfer, export, or forwarding
- Use inconsistent with the Terms and Conditions
- Claims where misuse, tampering, contamination, improper handling, or loss of chain of custody is indicated
- Fraudulent, abusive, duplicate, altered, or materially misleading claims
- Claims unsupported by reasonably requested documentation
These exclusions do not apply when Paramount Peptides initiates a recall or corrective action or when a right or remedy cannot legally be excluded.
10. Claim Review and Verification
Paramount Peptides may use any reasonably available records to evaluate a claim, including:
- Order and payment records
- Product and lot records
- Warehouse inventory
- Package weight
- Packing and fulfillment records
- Shipping and tracking information
- Photographs or video
- Customer account history
- Carrier investigation results
- Relevant analytical documentation
Paramount Peptides may request additional information, original files, identity verification, a signed declaration, or cooperation with a carrier investigation.
Failure to provide reasonably requested information within the timeframe specified by Paramount Peptides may result in closure or denial of the claim.
Paramount Peptides reserves the right to deny claims that cannot be substantiated, contain conflicting information, show evidence of misuse or alteration, or are reasonably suspected to be fraudulent or abusive.
11. How to Submit a Claim
Submit claims by email to:
Email: support@paramountpeptides.com
Subject: “CLAIM – Order #[Order Number]”
The initial email must be received within the applicable claim period and must include the required documentation.
A message stating only that there is a problem, without the order number and reasonably required supporting information, may not be considered a complete claim.
We generally acknowledge complete claims within two to three business days. Complex claims, carrier investigations, analytical reviews, or claims requiring additional documentation may take longer to resolve.
12. Product Retention and Unauthorized Returns
Do not mail, ship, or otherwise return any product to Paramount Peptides unless you receive prior written authorization and return instructions.
Research Products returned without authorization cannot be restocked and may be refused, quarantined, or destroyed without refund.
Customers must retain the affected item, shipping materials, labels, and all packaging until the claim is resolved or Paramount Peptides provides written return or disposal instructions.
Disposing of, transferring, using, or altering an item before the review is completed may prevent verification and result in denial of the claim.
13. Available Resolutions
If Paramount Peptides verifies a qualifying claim, Paramount Peptides may, at its option and subject to applicable law:
- Replace the affected item; or
- Refund the amount actually paid for the affected item to the original payment method.
Paramount Peptides does not issue store credit.
Replacement is the preferred resolution when an identical item is available. Paramount Peptides may issue a refund when replacement is unavailable, impractical, or otherwise determined appropriate.
A refund is limited to the amount actually paid for the affected item after discounts, promotions, rewards, or other price adjustments, plus applicable tax.
Shipping charges are refundable only when the entire shipment is affected by a verified Paramount Peptides error or when otherwise required by law. Original shipping charges are otherwise non-refundable.
Paramount Peptides is not required to refund unaffected items in the same order.
Once an approved replacement has been delivered, the replacement constitutes resolution of the original claim, subject to any non-waivable rights under applicable law.
Only one resolution will be provided for each verified affected item.
14. Refund Processing
Approved refunds will be initiated to the original payment method, generally within five to seven business days after approval.
After Paramount Peptides initiates the refund, the customer’s bank, credit card company, or payment provider may require additional time to post the funds.
Where applicable law requires a refund within a shorter period, the legally required period will apply.
If more than 15 business days have passed since Paramount Peptides confirmed that a refund was initiated, contact support@paramountpeptides.com.
15. Replacement Shipments
Approved replacements are generally processed within one to two business days, subject to product availability, verification, and completion of any required investigation.
The customer will receive updated tracking information when the replacement ships. Standard processing and delivery estimates apply.
Paramount Peptides may require a signature for delivery or use another reasonable delivery-verification method for replacement shipments.
Replacement approval does not restart or extend the claim period for unrelated items in the original order.
16. Recalls and Corrective Actions
If Paramount Peptides initiates a product recall, withdrawal, or other corrective action, the instructions provided in that notice will control.
Any remedy offered through a recall or corrective action will not be restricted by the ordinary claim deadlines in this Policy.
17. U.S. Shipping Only
Paramount Peptides currently ships only within the United States.
Orders may not be exported, forwarded internationally, or shipped through a freight-forwarding service without prior written authorization from Paramount Peptides.
Paramount Peptides is not responsible for loss, seizure, delay, degradation, additional fees, or other issues arising from an unauthorized export or international forwarding arrangement.
18. Research-Use Notice
Research Products sold by Paramount Peptides are intended solely for in vitro laboratory research.
They have not been approved by the U.S. Food and Drug Administration for human or veterinary use and are not offered for diagnosing, treating, curing, mitigating, or preventing any disease or medical condition.
Paramount Peptides does not provide guidance regarding human or animal dosing, administration, consumption, or bodily application.
Communications indicating intended use inconsistent with legitimate laboratory research may result in cancellation of unshipped orders, account restriction, refusal of future service, or other action permitted under the Terms and Conditions.
19. Applicable Law
Nothing in this Policy excludes, restricts, or limits any right, remedy, warranty, or obligation that cannot lawfully be excluded, restricted, or limited.
If any provision of this Policy conflicts with applicable law, the applicable legal requirement will control only to the extent of that conflict. All remaining provisions will continue in effect.
