Frequently asked questions

When will my order ship?

Orders are typically processed and dispatched within 24–48 business hours of payment confirmation. Once your order ships you will receive an email with your tracking number and carrier details. Shipping fees are calculated at checkout.

My order arrived damaged or incorrect. What do I do?

Email support@synexbiolabs.com within 72 hours of delivery with your order number and clear photos of the damage or error. Verified damaged or incorrect items are replaced at no additional cost.

Can I cancel my order?

One-time orders can be cancelled only before they have been processed for shipping. Email us right away with the subject “Cancel Order #[your order number]”; emailing within the first hour gives the best chance of catching the order. See the Cancellation Policy for full details, including subscriptions.

Can I return a product?

Because research peptides require strict storage and chain-of-custody standards, all sales are final once a product leaves our facility. See Shipping & Returns for the complete policy.

My tracking says delivered, but I don’t have my package.

Please contact the carrier first. If the package is confirmed lost in transit and is not marked delivered, email us and we will investigate with the carrier on your behalf.

Where can I find a Certificate of Analysis?

Every lot is independently third-party tested. Request the COA and Safety Data Sheet for your lot on the Verify Your COA page.
