Specifications
Lab reports
We independently test selected batches. Each report covers the lot number shown on it.
Shipping & Storage
Shipping
Orders ship within 24 hours. Delivered via USPS Priority or standard FedEx unless expedited shipping is selected at checkout. Tracking is emailed on dispatch and mirrored in your account.
In-transit handling
Lyophilized vials are shelf-stable and ship at ambient temperature. Storage in our warehouse is cooled; shipment does not require refrigeration.
Long-term storage
Lyophilized vials are shelf-stable at ambient temperature; refrigeration (2–8°C) extends shelf life. Where a published Certificate of Analysis exists for your strength and origin, it is on the COA tab. Not for human or animal consumption.
Returns
Because these are research-grade biologics, we cannot accept returns on opened vials. Damaged-in-transit shipments are replaced at no cost within 7 days of delivery.
Frequently asked
We independently test selected batches at a third-party lab and publish those certificates of analysis. Not every batch has one. The COA tab on each product shows whether the strength and origin you picked has a published report.
