Refund & Return Policy

Last updated — March 2026

1. Scope

This policy applies to all research-grade peptide reagents and related laboratory products purchased through kayethelpeptides.com. Due to the nature of chemical reagents and strict quality-control requirements, returns and refunds are handled on a case-by-case basis as outlined below.

2. Quality Guarantee

Every product ships with a batch-specific Certificate of Analysis (COA) documenting HPLC purity, mass spectrometry confirmation, and endotoxin testing where applicable. If a product does not meet the specifications stated on its COA, you are entitled to a full replacement or refund.

3. Eligible Refund & Replacement Scenarios

  • Product does not meet COA specifications — Full refund or replacement at no charge. You must provide analytical evidence (e.g., independent HPLC data) demonstrating the discrepancy within 30 days of receipt.
  • Damaged in transit — Full refund or replacement. Report damage within 48 hours of delivery with photographic documentation of the packaging and product.
  • Incorrect product shipped — Full refund or replacement. Notify us within 7 days of receipt. We will arrange return shipping at our expense.
  • Order cancellation — Orders may be canceled for a full refund if the request is received before the order enters the fulfillment queue (typically within 2 hours of placement).

4. Non-Refundable Scenarios

  • Change of mind — Due to the sensitive nature of research reagents, we cannot accept returns for products that have been opened or reconstituted.
  • Improper storage — Products that have been stored outside the conditions specified on the label (e.g., lyophilized peptides exposed to moisture or elevated temperatures) are not eligible for refund.
  • Regulatory restrictions — If a product cannot be delivered due to import/export regulations in your jurisdiction, shipping charges are non-refundable.
  • Delayed claims — Claims submitted more than 30 days after delivery are not eligible for refund or replacement.

5. How to Request a Refund

  1. Email support@kayethelpeptides.com with your order number, product name, and a description of the issue.
  2. Attach any supporting documentation (photos, independent analytical data, COA comparison).
  3. Our quality team will review the request within 3 business days.
  4. If approved, refunds are processed to the original payment method within 5–10 business days. Replacements ship within 2 business days of approval.

6. Return Shipping

For approved returns, Kayethel Peptides will provide a prepaid shipping label. Products must be returned in their original sealed packaging. Opened or reconstituted products cannot be accepted for return due to contamination and cold-chain integrity concerns.

7. Restocking Fees

No restocking fees are charged for defective or incorrectly shipped products. Cancellations made after the order has entered fulfillment may be subject to a 15% restocking fee to cover handling and packaging costs.
