1. Policy Overview

This Refund & Return Policy ("Policy") governs all purchases made through the website at optidesxi.com (the "Site") operated by Optides LLC ("Company," "we," "us," or "our"). This Policy is incorporated by reference into our Terms of Service.

Due to the nature of our products — research-grade chemicals, peptides, and laboratory materials intended solely for in vitro research — all sales are final and we generally do not offer refunds, returns, exchanges, or cancellations. This Policy explains our position in detail, outlines the extremely limited circumstances under which exceptions may be considered at our sole discretion, and describes the procedures that apply.

By placing an order on the Site, you acknowledge that you have read, understood, and agree to this Policy in its entirety.

2. All Sales Are Final

ALL SALES ARE FINAL. BY COMPLETING A PURCHASE ON OPTIDESXI.COM, YOU ACKNOWLEDGE AND AGREE THAT YOUR ORDER IS NON-REFUNDABLE, NON-RETURNABLE, AND NON-EXCHANGEABLE, EXCEPT AS SPECIFICALLY DESCRIBED IN THE EXTREMELY LIMITED EXCEPTIONS IN SECTION 8 OF THIS POLICY.

This all-sales-final policy is clearly disclosed:

On the Site footer (visible on every page);
On product pages;
During the checkout process;
In order confirmation emails;
In these Terms;
In this Policy.

By completing your purchase, you confirm that you were aware of and agreed to this policy before placing your order.

3. No Refunds — General Rule

Optides LLC does not issue refunds for any reason, including but not limited to:

Change of mind, buyer's remorse, or reconsideration after purchase;
Dissatisfaction with product for any reason that is not a verifiable defect;
Products not meeting your personal expectations, preferences, or assumptions about performance in your specific research application;
Ordering the wrong product, wrong quantity, or wrong concentration;
Failure to read product descriptions, specifications, or sizing/quantity information before ordering;
Inability to use the product due to lack of equipment, facilities, expertise, or supplies;
Changes in your research plans, project cancellation, or loss of funding;
Regulatory changes in your jurisdiction that affect legality of possession or use;
Price changes after your purchase;
Finding a lower price elsewhere after your purchase;
Products that have been opened, unsealed, reconstituted, mixed, diluted, or altered in any way;
Products that have been improperly stored by the Buyer after delivery;
Products past the manufacturer's or our recommended storage timeframe if applicable;
Any situation not explicitly covered in the Extremely Limited Exceptions (Section 8).

4. No Returns — General Rule

Optides LLC does not accept returns of any products for any reason. Once a product has been shipped and delivered, it is the property and responsibility of the Buyer. We cannot accept any product back due to:

Safety and integrity concerns: We cannot verify that returned products have been stored, handled, or maintained properly after leaving our facility. Accepting returns would compromise our ability to guarantee the purity, integrity, and safety of products for all customers.
Regulatory compliance: Accepting returns of research chemicals and peptides raises significant regulatory, safety, and liability concerns, including potential contamination, adulteration, and chain-of-custody issues.
Health and safety: Research chemicals may pose hazards during transportation, and accepting returns increases the risk of accidental exposure or environmental contamination.

Under no circumstances will we provide return shipping labels, accept returned packages, or issue credit for returned products. Any products returned to us without prior authorization will be destroyed and no refund or credit will be issued.

5. No Exchanges — General Rule

Optides LLC does not offer exchanges. If you ordered the wrong product, wrong quantity, or wrong variant, you must place a new order for the correct item. We will not exchange products already shipped or delivered.

6. No Cancellations After Processing

Orders move into processing rapidly. Once an order has been submitted and payment has been processed:

Before shipment: We may, at our sole discretion, consider cancellation requests submitted within one (1) hour of order placement, provided the order has not yet been picked, packed, or handed off to a shipping carrier. There is no guarantee that any cancellation request will be honored. Contact us immediately at optidesxi@gmail.com.
After shipment: Orders that have been shipped cannot be cancelled, returned, or refunded. Once a shipping label has been generated and/or the order has been tendered to a carrier, the sale is complete and final.
Cancellation fees: If a cancellation is approved before shipment, we reserve the right to deduct a restocking fee of up to 15% of the order total to cover processing and handling costs. Payment processing fees charged by third-party processors are non-recoverable and will not be refunded.

7. Why All Sales Are Final

We maintain a strict all-sales-final policy for the following important reasons:

Product integrity: Research chemicals and peptides must maintain an unbroken chain of custody with verified storage conditions. Once a product leaves our facility, we cannot verify that it has been stored at the required temperature, kept sealed, and handled properly. Re-selling previously shipped products would compromise our quality standards and put other customers at risk.
Contamination risk: Research chemicals can be contaminated through improper handling, exposure to air, moisture, heat, or light, or contact with other chemicals. We cannot re-introduce potentially compromised materials into our inventory.
Regulatory considerations: The sale of research chemicals is subject to regulatory scrutiny. A robust chain-of-custody and no-return policy demonstrates that we take product integrity and compliance seriously.
Fraud prevention: All-sales-final policies protect against fraudulent return schemes, including attempts to return counterfeit, substituted, diluted, or partially used products.
Industry standard: All-sales-final is the recognized industry standard for research chemical and peptide suppliers.

8. Extremely Limited Exceptions

Optides LLC may, at our sole and absolute discretion, consider providing a remedy (replacement, store credit, or in extremely rare cases a partial refund) only in the following limited circumstances:

Exception A — Incorrect Product Shipped

If we shipped a product that is demonstrably different from what you ordered (wrong product entirely, wrong variant, or wrong catalog number), and you can provide evidence, we may consider a remedy.

Exception B — Shipping Damage (Carrier Fault)

If a product arrives with visible physical damage to the vial, container, or packaging that clearly occurred during transit (e.g., broken vial, crushed packaging with leaked contents), and you document it with photographs immediately upon receipt, we may consider a remedy.

Exception C — Verifiable Purity Defect

If a product's purity demonstrably does not match the specifications stated on its Certificate of Analysis (COA), and you can provide independent third-party laboratory test results from a reputable, accredited laboratory conducted on an unaltered sample that contradict our COA, we may consider a remedy. Your own in-house testing alone is generally not sufficient; we require independent, accredited third-party verification.

These are the ONLY circumstances under which any remedy may be considered. Meeting the criteria above does not guarantee a refund, replacement, or credit. All exception determinations are made at our sole and absolute discretion.

9. Exception Eligibility Requirements

To be considered for any exception under Section 8, ALL of the following requirements must be met:

Timeliness: You must contact us within five (5) calendar days of receiving your order. Claims submitted after 5 days will be automatically denied with no further review.
Order number: You must provide your original order number.
Photographic evidence: You must provide clear, high-resolution photographs showing the issue. For shipping damage: photographs of the damaged product AND the outer shipping packaging. For incorrect products: photographs of the product label showing lot number, product name, and the product received versus what was ordered.
Unaltered product: The product must be in its original, unopened, unmixed, unreconstituted, unaltered, and undiluted condition. If the product has been opened, unsealed, reconstituted, mixed, diluted, transferred to another container, or altered in any way, no exception will be granted.
Original packaging: The product must be in its original packaging with all labels intact.
No prior use: The product must not have been used in any experiment, assay, or research application, even partially.
Proper storage: You must have stored the product according to the storage conditions indicated on the product label and/or SDS from the time of delivery until the time of your claim.
Good faith: The claim must be made in good faith with no evidence of fraud, misrepresentation, or abuse.

Failure to meet any single requirement above will result in automatic denial of the exception request.

10. How to Submit an Exception Request

If you believe your situation falls under one of the Extremely Limited Exceptions (Section 8) and you meet all eligibility requirements (Section 9), submit your request as follows:

Email: optidesxi@gmail.com Subject line: "Exception Request — Order #[your order number]"

Your email must include:

Your full name and email address associated with your account;
Your order number;
Date of order and date of delivery;
Clear description of the issue;
Specific exception category (A, B, or C from Section 8) you believe applies;
Photographic evidence as described in Section 9;
For Exception C (purity defect): independent third-party laboratory test results;
Any other supporting documentation.

Incomplete submissions will not be reviewed and will be returned for completion. The 5-day submission window still applies — you cannot extend the deadline by submitting an incomplete claim first.

11. Investigation & Determination Process

Upon receiving a complete exception request:

We will acknowledge receipt within 2 business days;
We will conduct an internal investigation, which may include reviewing order records, warehouse documentation, shipping carrier data, batch/lot records, COA data, and your submitted evidence;
We may request additional information or evidence from you;
We may, at our discretion, request that you return the product for inspection at our expense (this is rare and does not constitute acceptance of a return);
We will communicate our determination within ten (10) business days of receiving all requested information;
Our determination is final and binding. There is no appeal process.

If we determine that an exception is warranted, the remedy will be one of the following, selected at our sole discretion:

Replacement of the affected product (preferred remedy);
Store credit for the value of the affected product;
Partial refund to the original payment method (rare, and only for the product value — never for shipping);
Full refund to the original payment method (extremely rare, reserved for clear Company error).

We reserve the right to deny any claim that we determine, in our sole judgment, does not meet the requirements of this Policy, shows evidence of fraud or abuse, or is otherwise not supported by the evidence presented.

12. Situations That Do NOT Qualify for Any Exception

The following situations will never qualify for a refund, replacement, credit, or any other remedy, regardless of circumstances:

Buyer's remorse, change of mind, or order regret;
Ordering the wrong product, quantity, concentration, or variant;
Dissatisfaction with product appearance, color, consistency, or form (lyophilized vs. liquid, powder appearance, etc.) where the product meets stated specifications;
Product not performing as expected in your specific research application (research outcomes are not guaranteed);
Inability to use the product due to lack of equipment, expertise, or supplies;
Changes in your research plans, project cancellation, budget changes, or loss of funding;
Delay in delivery caused by shipping carrier, weather, or events outside our control;
Products seized, confiscated, or destroyed by customs, border control, or government authorities;
Regulatory changes in your jurisdiction;
Price reductions, sales, or promotions occurring after your purchase;
Products that have been opened, unsealed, reconstituted, mixed, diluted, or altered;
Products stored improperly by the Buyer (e.g., not refrigerated when required);
Products past the recommended use-by or storage date;
Claims submitted after the 5-day window;
Claims without required documentation;
Duplicate or repeat claims for the same order;
Claims that show evidence of fraud, misrepresentation, tampering, or abuse;
Products returned without prior written authorization (will be destroyed on receipt);
Any situation where the Buyer violated the Terms of Service, Research Use Disclaimer, or this Policy.

13. Shipping Damage Claims

If your order arrives with visible shipping damage:

Document immediately: Photograph the outer shipping packaging, inner packaging, and the damaged product(s) before discarding any packaging materials.
Do not discard packaging: Keep all original shipping materials (box, padding, labels, packing slip) as they may be needed for a carrier claim.
Contact us within 5 days per Section 10.
We may file a claim with the shipping carrier on your behalf. Carrier claim outcomes are not guaranteed and are subject to the carrier's own policies and investigation.
If we determine the damage was caused by the carrier and the product is unusable, we may, at our discretion, send a replacement or issue store credit. This is not guaranteed.
We are not responsible for damage caused by carriers. Risk of loss passes to you upon delivery to the carrier (see Terms of Service, Section 14).

14. Lost or Missing Packages

If your tracking information shows "delivered" but you have not received the package:

Check with household members, neighbors, building management, and mail rooms;
Check all delivery locations around your property;
Wait an additional 3 business days — carriers sometimes scan items as delivered prematurely;
Contact the shipping carrier directly to open an investigation;
Contact us within 7 calendar days of the marked delivery date.

If the carrier confirms the package is lost (not merely delayed), we may, at our discretion, resend the order or issue store credit. We are not responsible for packages marked as delivered by the carrier, stolen from the delivery location (porch piracy), or misdelivered due to carrier error.

If tracking shows a package is in transit but delayed beyond the estimated delivery window, this is a carrier issue and does not qualify for any refund or replacement. We will assist with carrier inquiries but cannot compensate for carrier delays.

15. Incorrect Orders

If we shipped a product that is different from what you ordered:

Verify by comparing the product label (name, catalog number, lot number) against your order confirmation;
Photograph the product label and your order confirmation showing the discrepancy;
Contact us within 5 days per Section 10;
If we confirm the error was ours, we will ship the correct product at no additional charge. We may or may not request return of the incorrect product.

Incorrect quantity claims must be supported by photographic evidence (e.g., packing slip showing ordered quantity vs. received quantity, photograph of all items received).

16. Defective Products

If you believe a product is defective (does not meet COA specifications):

The product must be unopened, unaltered, and stored properly since receipt;
You must provide independent third-party laboratory test results from an accredited laboratory demonstrating that the product's purity or identity does not match the COA;
Your own internal testing is generally insufficient — we require independent accredited verification;
Contact us within 5 days of receipt per Section 10;
We will review your third-party results against our internal quality records;
If we confirm a defect, we may provide a replacement from a different lot or issue store credit. Refunds for defective products are extremely rare and determined solely at our discretion.

17. Partial Shipments & Backorders

If your order contains items that are temporarily out of stock:

We may ship available items and backorder the remaining items;
You will be notified of any backordered items via email;
Backordered items will be shipped when available at no additional shipping cost;
You will not be charged for backordered items until they ship;
If a backordered item becomes permanently unavailable, we will notify you and issue store credit or a refund for that specific item only.

Receiving a partial shipment does not entitle you to a refund for delivered items.

18. Credit & Store Credit

If an exception is granted, our preferred remedy is store credit rather than a monetary refund. Store credit:

Is issued to your account on the Site;
Has no expiration date (unless otherwise stated at time of issuance);
Is non-transferable and cannot be redeemed for cash;
Must be used for purchases on optidesxi.com;
Cannot be combined with certain promotions (at our discretion);
Is not replaceable if lost (e.g., account deletion).

19. Refund Processing (If Approved)

In the extremely rare cases where a monetary refund is approved:

Refunds are processed to the original payment method only;
Refund processing takes up to 14 business days from the date of approval;
Credit card refunds may take an additional 5–10 business days to appear on your statement, depending on your bank or card issuer;
Cryptocurrency refunds will be issued at the USD value at the time of the original purchase, not at current market value;
Shipping costs are non-refundable in all circumstances;
Payment processing fees charged by third-party processors (e.g., PayPal fees, Stripe fees) are non-recoverable and will be deducted from any refund;
Refunds are issued for the product value only, minus any applicable fees, restocking charges, or deductions.

20. Chargeback & Payment Dispute Policy

Filing a chargeback or payment dispute with your bank, credit card company, or payment processor is a serious matter and will be vigorously contested.

Before filing a chargeback:

You must first contact us directly at optidesxi@gmail.com to attempt to resolve the issue. We are committed to working with you in good faith.
If you file a chargeback without first contacting us, or if you file a chargeback that we determine to be unjustified, fraudulent, or in violation of this Policy, we will:
- Submit comprehensive evidence to your payment processor/bank to contest the chargeback, including order records, tracking data, delivery confirmation, IP logs, acceptance of our Terms of Service, and this Policy;
- Permanently terminate your Account with no option for reinstatement;
- Ban you from future purchases;
- Pursue all available legal remedies, including but not limited to collection of the original order amount, chargeback fees incurred by us, attorneys' fees, collection agency costs, and any other damages;
- Report fraudulent chargebacks to fraud prevention databases and, where appropriate, to law enforcement.

Chargebacks are intended as a consumer protection mechanism for unauthorized or fraudulent transactions. Filing a chargeback because you changed your mind, are dissatisfied with a product, or failed to read our all-sales-final policy before purchasing is an abuse of the chargeback process and may constitute fraud.

21. Fraud Prevention & Abuse

We employ fraud prevention systems and monitor for patterns of abuse, including:

Multiple refund/exception requests from the same individual or entity;
Claims of non-receipt with tracking showing delivery;
Claims of damage without photographic evidence;
Claims of defect without independent testing;
Frequent chargebacks;
Use of multiple accounts to circumvent our policies.

We reserve the right to permanently ban any individual or entity suspected of abuse, fraud, or manipulation of our refund processes. Suspected fraud may be reported to law enforcement.

22. Shipping Cost Responsibility

Original shipping costs are non-refundable in all circumstances, including approved exceptions.
Return shipping costs (if we request product return for inspection) will be covered by Optides LLC when the exception is related to Company error.
Re-shipment costs for address errors, refused deliveries, or undeliverable packages are the Buyer's responsibility.

23. Address Errors & Undeliverable Packages

You are solely responsible for providing accurate and complete shipping information at checkout.
We are not responsible for orders shipped to incorrect addresses that you provided.
If a package is returned to us due to an incorrect address, refused delivery, or unclaimed package, we may, at our discretion, reship the order if you pay the additional shipping cost. No refund will be issued.
Packages returned to us that are not claimed or reshipped within 30 days will be destroyed. No refund or credit will be issued.

24. International Orders

If we offer international shipping (at our discretion):

All international sales are final with no exceptions;
We are not responsible for customs duties, taxes, fees, or charges imposed by your country;
We are not responsible for packages seized, confiscated, held, destroyed, or delayed by customs, border control, or government authorities;
Refusal to pay customs charges resulting in return of the package does not qualify for a refund;
Delivery time estimates for international orders are approximations only and delays are not grounds for refund;
Import restrictions and legality of products in your country are your sole responsibility.

25. Promotional Orders, Discounts & Coupon Codes

Orders placed using promotional pricing, discount codes, coupon codes, loyalty rewards, or other special offers are final with no exceptions;
Store credit for exception-eligible orders placed with a discount will be calculated based on the amount actually paid (after discount), not the original list price;
Promotional offers cannot be applied retroactively to previously placed orders;
Free or complimentary items included with orders have no cash value and are not eligible for refund or credit.

26. Product Discontinuation

If a product you ordered is discontinued after your purchase but before shipment:

We will notify you and offer a substitute product of equivalent or greater value;
If no substitute is acceptable to you, we will issue a refund for the discontinued item only;
Discontinuation of a product after delivery does not entitle you to a refund or exchange.

27. Force Majeure & Delays

We are not liable for failures or delays in fulfillment caused by force majeure events, including natural disasters, pandemics, government actions, supply chain disruptions, carrier delays, or other events beyond our reasonable control. Such events do not entitle you to a refund, cancellation, or credit.

28. Limitation of Liability for Refund Claims

Our maximum liability with respect to any refund, return, or exchange claim is limited to the purchase price of the specific product at issue. In no event shall we be liable for shipping costs, consequential damages, incidental damages, lost profits, lost research time, or any other damages arising from or related to a refund or return claim.

29. Modifications to This Policy

Optides LLC reserves the right to modify this Policy at any time. Changes will be posted on this page with an updated effective date. The Policy in effect at the time of your purchase governs that transaction. Continued use of the Site after modifications constitutes acceptance for future orders.

30. Relationship to Other Agreements

This Policy is incorporated by reference into our Terms of Service. It should be read together with our:

In the event of conflict between this Policy and the Terms of Service, the more restrictive provision (from the Company's perspective) shall control.
