Provenance

Supply chain and provenance

ExaVeyra Sciences is a distributor. We do not manufacture the products we sell, and this page says who does. Elsewhere on this site we tell clinics to verify a supplier's registration before ordering, so it would be a poor sort of advice if we made ourselves harder to check than the suppliers we describe.

Exosome material

The Luxir, Luxir+, Kiara and Vive families are manufactured by Kimera Labs. Kimera is named on every product page as the brand, and it is the establishment a clinic would look up when verifying where this material comes from. Material is pulled from characterised lots, so preparation runs 1 to 2 business days and the cold-chain leg ships overnight on top of that.

Establishment registration

We are confirming the manufacturer's current establishment registration directly with them before publishing it here, rather than reproducing a number from a secondary source. In the meantime the registry below is public and you can search it yourself by firm name.

Compounded formulations

Compounded formulations are prepared by our 503A pharmacy partner, a compounding pharmacy licensed by the Texas State Board of Pharmacy. Preparation and transit together run 3 to 5 business days, because a 503A preparation is made to order against a prescription for a named patient rather than pulled from stock.

We state the pharmacy's credential publicly and disclose its identity after a clinic application and NPI verification. The credential is the part that tells you whether the preparation was made under a licence you can check.

How to verify an establishment yourself

FDA publishes a searchable registry of human cell and tissue establishments. Search it by firm name:

FDA Tissue Establishment Registration search

A state board of pharmacy licence can be verified the same way, through the issuing board's own lookup. Both registries are first-party government sources, which is why we point at them rather than summarising what they say.

What registration does and does not mean

Establishment registration records that a facility has told FDA it exists and what it does. It carries no finding about any particular product. FDA does not approve or clear a product by registering the establishment that makes it, and a registration number is not a substitute for the approval or clearance pathway that a given product may or may not have.

This matters for exosome material specifically. FDA's position is that exosome products fall outside the 361 HCT/P pathway, which is set out in detail on our 361 HCT/P versus 351 biologic page. Anyone reading a registration as a signal of product approval has read more into it than it holds.

Documentation that travels with an order

  • A Certificate of Analysis for the lot, held on file and produced on request.
  • Lot numbers and expiry, printed on the container.
  • Cold-chain handling on exosome shipments, which ship overnight.

We describe the COA as available on request because that is the mechanism in place today. When it ships unrequested with every lot, this page will say so.
