Returns & replacements

We take every precaution to ensure your research products arrive in excellent condition. If your order is damaged during transit, we’ll replace the affected items one time at no additional cost.

Email support@firstchoicepeptides.com within 48 hours of delivery with your order number and clear photo documentation of the package and its contents. All claims are reviewed before approval. Limit one replacement per order.

For safety and research-integrity reasons, vials cannot be returned once shipped — opened or reconstituted included. Replacements under the Transit Protection Guarantee are issued as replacement product, not as refunds.

Purchases are subject to our separate Return and Refund Policy, which is incorporated into these Terms by reference.

Unless otherwise required by law or expressly stated in that policy:

• Sales are final;
• Returns or refunds are not provided for a change of mind, dissatisfaction, improper use, improper storage, improper handling, or unsuccessful research outcomes;
• Products that have been opened, reconstituted, altered, contaminated, improperly stored, or otherwise handled after delivery are not eligible for return or replacement;
• Damage claims must be submitted within the period stated in our Return and Refund Policy;
• Claims must include clear photographic evidence of the product, packaging, shipping label, and alleged damage;
• Damage claims are subject to investigation and approval; and
• An approved transit-damage claim may qualify for one replacement of the affected product.
