Send research inquiries, bulk-order questions, or COA support details. FAQ, COA records, and the catalog are one tap away.
USPS, United States only.
The contact form covers the four research-context channels we hear from most: research bulk-quantity inquiries, certificate of analysis questions about a specific batch, technical questions about compound identity / molecular data / storage, and packaging or shipping logistics. For order status, payment, or return questions, email directly is fastest. Therapeutic, dosing, or human-use questions cannot be answered — Nexus supplies compounds for in-vitro research only and does not provide medical guidance.
Support inquiries, COA verification questions, and technical-compound questions are routed through the same research support mailbox. Include the relevant order number, product, or batch ID so the request can be matched to the right record. Outbound replies come from [email protected] — add it to your safe-sender list if your institution filters external mail aggressively.
The Lab Verified page documents the third-party verification methodology in full, the peptide research database indexes all 95 compounds with reference data, and the FAQ answers common research-context questions about handling, storage, COAs, and shipping.
