We are here to help with questions about our products, your orders, shipping, quality documentation, and anything else related to your research compound needs. Our team is staffed by individuals with scientific backgrounds who can engage meaningfully with technical inquiries — not just order management. We take pride in providing thoughtful, substantive responses to every inquiry we receive.
The best way to reach us is by email. We monitor our support inbox throughout the business day and aim to respond to all inquiries within 24 hours on business days. For technical or complex questions, we may occasionally require slightly more time to provide a fully researched response — in those cases, we will acknowledge your message promptly and let you know when to expect a complete reply.
Email: [email protected]
Our support team is available Monday through Friday, 9:00 AM to 6:00 PM (GMT). Emails received outside of business hours or over the weekend will be addressed on the next business day. For urgent order-related matters received outside of business hours, please include “URGENT” in your subject line and a member of our on-call team will review your message as soon as possible.
To ensure we can respond as quickly and accurately as possible, please include the following information in your message where relevant:
Our team can assist with a range of technical questions related to our products and their use in laboratory research. We regularly help researchers with questions about reconstitution solvents and protocols, storage and stability recommendations, compound selection for specific research applications, interpretation of Certificate of Analysis data, HPLC and mass spectrometry methodology, and compatibility of our compounds with specific assay systems.
We are not able to provide guidance on dosing, in-vivo administration, or any application outside of controlled in-vitro laboratory research. All of our products are supplied exclusively for research purposes, and our scientific support reflects that scope. If your question falls outside of in-vitro research applications, we will let you know clearly and respectfully.
For all order-related matters — including order placement assistance, payment questions, delivery tracking, reshipment requests, and refund inquiries — our order support team is ready to help. Please include your order number in all order-related communications to help us locate your records quickly and provide faster service.
If you have not received a shipping confirmation email within 24 hours of placing your order on a business day, or if your tracking information has not updated within 48 hours of dispatch, please reach out so we can investigate. In the vast majority of cases, these situations are resolved quickly with minimal disruption to your order timeline.
Researchers and institutions with high-volume requirements, recurring supply needs, or interest in custom peptide synthesis are encouraged to contact our sales team directly at [email protected] with the subject line “Bulk Inquiry” or “Custom Synthesis Request.”
For bulk orders, we can discuss volume pricing, dedicated inventory reservations, custom packaging configurations, flexible delivery scheduling, and institutional account arrangements including purchase order billing. For custom synthesis, our team will work with you to define specifications, provide a detailed quotation, and establish a production timeline suited to your research schedule.
