Every lot,
documented.

Our products are supplied for laboratory research. They are not drugs, supplements, cosmetics or food, are not intended for human or veterinary consumption, and have not been evaluated by the FDA or any equivalent authority. Nothing on this site is a medical claim.

A COA is the laboratory report for a specific production lot. It records what was tested, the method used and the result. A COA applies only to the lot identified on it, which is why every lot has its own and why the lot number is printed on the label.

The lot number is on the product label. Enter it in the COA Library and the certificate for that lot will come up. You can also check a lot before ordering.

Orders are packed to hold temperature in transit and tracked from dispatch to delivery. Methods, costs and estimated delivery times are shown at checkout; estimates are not guarantees. For international orders you are the importer of record and responsible for duties and customs compliance.

Opened products cannot be returned. Unopened products in their original packaging can be returned within 14 days of delivery — contact support@vionlabs.co first. Report damaged or incorrect items within 14 days.

Yes. Lyophilised products are supplied as a powder and need reconstitution; bacteriostatic water is not included and is ordered separately. Our oral spray is supplied as a liquid and needs no diluent.
