Our products are sold exclusively for laboratory research, analytical chemistry, and educational purposes. They are not for human or animal consumption, are not drugs, and are not approved by the FDA for any therapeutic use. All buyers must confirm research-use intent at checkout.

Verified batches are documented at ≥99% purity via High-Performance Liquid Chromatography (HPLC) through manufacturer-issued testing. The exact purity percentage for each lot is published on the product page and can be confirmed on our Quality & COA page. A manufacturer COA is on file for every batch we document; check each product page for its current status.

Every order ships with a COA PDF. You can also visit our Quality & COA page to look up documentation by product and lot number. For additional verification, contact info@bioreceptorlabs.com with your lot number and we will provide confirmation within 24 hours.

No. As a Research Use Only supplier, we do not provide administration protocols, reconstitution protocols for personal use, injection guidance, or any instructions related to human or animal administration. Our products are reference materials for qualified researchers.

All lyophilized peptide compounds should be stored at -20°C for long-term storage or 2–8°C for short-term use. Avoid repeated freeze-thaw cycles. Specific storage recommendations are included on each product page and COA.

We are evaluating institutional and volume ordering programs. If you represent a university, research institution, CRO, or licensed laboratory and are interested in volume orders, please contact us to discuss your research needs. Institutional inquiries are reviewed on a case-by-case basis.

Due to the nature of our lyophilized research compounds and strict quality control standards, all sales are final once shipped. We cannot accept returns because once a product leaves our facility, we cannot verify that it has not been opened, tampered with, or compromised. However, we will make it right in these situations: (1) Wrong product shipped — we will send the correct product at no charge. (2) Product damaged during shipping — contact us within 48 hours of delivery with photos of the damage, and we will send a replacement. (3) Order lost or never delivered — we will file a carrier claim and reship your order or issue store credit. All claims must be submitted within 48 hours of delivery (or expected delivery date for lost packages). Contact us with your order number and photos if applicable.

For product questions, order status, COA requests, or general inquiries, email us at info@bioreceptorlabs.com. We respond within 24 hours on business days (Monday through Friday). For urgent order issues, include your order number in the subject line for fastest response.
