Effective date: September 11, 2026
This Refund Policy applies to purchases of Helix Aminos products from tgrleafy.com. Helix Aminos is operated by TGR Leafy LLC (“Helix Aminos,” “TGR Leafy,” “we,” “us,” or “our”). Please review this policy before placing an order.
1. All Sales Are Final
ALL SALES OF HELIX AMINOS PRODUCTS ARE FINAL. Because our products are sensitive laboratory research materials whose identity, integrity, storage, handling, chain of custody, and environmental exposure cannot be verified after shipment, we do not accept returns or exchanges.
Except where applicable law requires otherwise or where we approve a remedy under this policy, we do not provide refunds, returns, exchanges, replacements, or store credit for:
- buyer’s remorse or a change of mind;
- an incorrect product, strength, quantity, or shipping address selected by the customer;
- changed, canceled, delayed, unsuccessful, or completed research;
- products that are unwanted, unused, opened, unsealed, altered, stored, handled, reconstituted, tested, or otherwise exposed after delivery;
- dissatisfaction based on expectations not expressly stated in the applicable product listing;
- inability to use a product for a prohibited human, veterinary, clinical, diagnostic, therapeutic, or personal purpose;
- failure to review product information, research-use restrictions, available batch documentation, or this Refund Policy before ordering;
- delays, deterioration, loss, or damage caused after delivery or by improper storage, handling, access control, or use;
- a customer’s failure to retrieve, receive, or accept a shipment; or
- an unauthorized resale, transfer, relabeling, redistribution, export, or other prohibited activity.
2. No Unauthorized Returns
Do not mail or deliver a product back to us unless we first provide written return instructions. Unauthorized returns may be refused, destroyed, or disposed of and will not create a right to a refund, replacement, exchange, or credit. For safety and chain-of-custody reasons, returned research materials will not be restocked or resold.
3. Shipping Damage, Missing Items, and Incorrect Items
You must inspect your shipment immediately after delivery. Claims involving visible shipping damage, missing items, or an item different from what appears on your order confirmation must be reported within five business days after the carrier records delivery.
Submit the claim to tgrleafy@gmail.com and include:
- your full name and order number;
- a clear description of the problem;
- photographs of the exterior shipping package, shipping label, internal packaging, product, vial, label, lot or batch information, and visible damage;
- the quantity affected; and
- any additional information reasonably requested for our investigation or carrier claim.
You must preserve the product, shipping container, label, and all packaging in their received condition until we complete our review. Discarding, altering, using, transferring, or returning an item before receiving instructions may prevent us from verifying the claim.
Submitting a claim does not guarantee approval. We may compare the claim with order, fulfillment, weight, inventory, photographic, carrier, tracking, delivery, payment, and account records and may request additional documentation.
4. Remedies for Approved Claims
If we verify that we shipped an incorrect item, omitted an item, or that an item was materially damaged during shipment, we may, at our election and subject to applicable law:
- replace the affected item;
- reship the missing or correct item;
- issue store credit; or
- refund the amount paid for the affected item.
Unless required by law, an approved remedy applies only to the verified affected item and does not entitle the customer to a refund of unaffected products, original shipping charges, upgraded shipping costs, or other expenses. We may require confirmation of the shipping address or other reasonable conditions before sending a replacement.
5. Lost, Stolen, Delayed, or Misdelivered Packages
Carrier delivery dates are estimates and are not guaranteed. If tracking shows that a package is delayed, lost in transit, or delivered to an incorrect location, contact us promptly so we can review available carrier information and determine whether a carrier claim is appropriate.
We are not responsible for:
- an inaccurate, incomplete, inaccessible, or undeliverable address supplied by the customer;
- a customer’s failure to collect or accept a shipment;
- theft, loss, damage, or exposure occurring after confirmed delivery;
- delivery instructions, forwarding requests, or address changes made directly with a carrier without our written approval; or
- delays caused by carriers, weather, natural disasters, government action, labor interruptions, security events, or circumstances outside our reasonable control.
Any replacement, credit, or refund for a carrier-related issue is subject to our investigation, the carrier’s records, insurance availability, and applicable law.
6. Order Changes and Customer Cancellations
Orders may enter processing promptly after submission. We do not guarantee that an order can be changed or canceled after it is placed. You may contact us immediately to request a change or cancellation, but the request is not approved unless we confirm approval in writing.
Once an order has been processed, packed, transferred for fulfillment, or shipped, it cannot be canceled or changed. Refusing delivery does not cancel an order or create a right to a refund.
7. Orders Canceled by Helix Aminos
We reserve the right to reject, hold, limit, or cancel any order, including because of inventory, pricing or listing errors, payment authorization, suspected fraud, prohibited use, compliance concerns, quantity limits, destination restrictions, or account activity.
If we cancel an order after collecting payment and do not fulfill the canceled portion, we will refund the amount collected for that portion to the original payment method. We are not responsible for bank holds, exchange-rate differences, financing charges, or processing delays imposed by a financial institution.
8. Product Appearance, Packaging, and Documentation
Product photographs are illustrative. Minor variations in packaging, label placement, color, vial appearance, or other non-material characteristics do not qualify for a refund or replacement when the product supplied corresponds to the ordered product.
A Certificate of Analysis (“COA”) or related analytical document applies only to the product and batch identified on that document. A COA is not a promise of suitability for a particular experiment and does not authorize human or veterinary use. A customer’s disagreement with analytical documentation, failure to independently verify a product for its intended lawful research, or use outside stated research restrictions does not create a right to return or refund.
9. Duplicate or Incorrect Charges
If you believe you were charged more than once for the same transaction or charged an amount inconsistent with your confirmed order, contact us promptly at tgrleafy@gmail.com. Include the order number and a description of the charge, but do not email a complete card number or security code.
If we verify a duplicate or incorrect charge, we will correct or refund the verified excess amount to the original payment method.
10. Refund Processing
Approved refunds are issued only to the original payment method unless applicable law requires another method. After we submit a refund, the payment processor, card network, acquiring bank, and issuing bank control when the credit appears. Processing commonly takes several business days and may take longer depending on the financial institution. We cannot accelerate or guarantee a bank’s posting time.
11. Chargebacks and Payment Disputes
Please contact us before initiating a payment dispute so we have an opportunity to review and resolve the concern. We may provide the payment processor or financial institution with relevant records, including the order, delivery confirmation, communications, research-use acknowledgment, accepted policy version, IP address, account information, and claim documentation, as permitted by law.
Nothing in this section prevents you from exercising a lawful payment-dispute right. Knowingly submitting false information or disputing a valid authorized charge may result in account termination, refusal of future orders, collection activity, or other remedies permitted by law.
12. Research-Use Restrictions
Helix Aminos products are offered solely for lawful laboratory, analytical, educational, or research purposes. They are not intended for human or veterinary use, consumption, administration, diagnosis, treatment, prevention, mitigation, or clinical application.
No refund, return, replacement, or credit will be provided because a product cannot lawfully or appropriately be used for a prohibited purpose. Suspected prohibited use may result in cancellation, account termination, refusal of future orders, and preservation or disclosure of relevant records as permitted or required by law.
13. Rights That Cannot Be Waived
This policy is intended to be enforced to the fullest extent permitted by law. Nothing in it limits a refund, cancellation, warranty, replacement, or other remedy that cannot lawfully be waived. Any legally required remedy will be provided according to applicable law.
14. Policy Changes
We may update this Refund Policy prospectively by posting a revised version with a new effective date. The version accepted when an order is placed will generally govern that transaction, except where applicable law requires otherwise.
