Due to the nature of our research-grade peptide products and strict quality control requirements, all sales are considered final. We do not accept returns or exchanges on opened or used products. However, we stand behind the quality of every product we ship and will work with you to resolve any legitimate issues with your order.
We will issue a full refund or replacement in the following circumstances: (1) You received the wrong product or wrong quantity. (2) Your order arrived visibly damaged or compromised during shipping. (3) Your product has a verifiable quality defect confirmed by our team. (4) Your order was lost in transit and confirmed undeliverable by UPS. All claims must be submitted within 48 hours of the delivery date.
Refunds will not be issued in the following cases: products that have been opened, used, or tampered with; orders where an incorrect shipping address was provided by the customer; orders refused at delivery without prior authorization; dissatisfaction based on research outcomes or results, as peptide efficacy varies by application; or claims submitted more than 48 hours after delivery.
To initiate a refund or replacement claim, email cs@structurabio.com within 48 hours of delivery. Include your order number in the subject line, a clear description of the issue, and photos of the product and packaging (required for damage claims). Our team will review your claim and respond within 1–2 business days with next steps.
Where possible, we prefer to resolve issues by sending a replacement product at no additional cost. If a replacement is not feasible (e.g., item is out of stock), we will issue a full refund to your original payment method. For manual payment methods (Zelle, Venmo, Cash App), refunds will be returned via the same payment method used for the original purchase.
Once your claim is approved, refunds are processed within 3–5 business days. For credit/debit card payments, the refund will appear on your statement within 5–10 business days depending on your bank. For manual payment methods (Zelle, Venmo, Cash App), refunds are typically sent within 1–2 business days of approval.
Every product we ship is backed by a Certificate of Analysis (COA) confirming purity and identity. If you have concerns about product quality that are supported by independent third-party testing, please contact us with the test results and we will review your case on an individual basis. We take product quality seriously and will always work to make things right.
If you are unsatisfied with the resolution offered by our support team, you may request an escalation by replying to your support email thread and asking to speak with a manager. We are committed to fair and transparent resolution of all customer concerns and will do our best to reach a satisfactory outcome.
Our support team is happy to help with any shipping-related questions or concerns.
