Lab Quality You Can Verify

We source through an established North American supply partner that vets the cGMP- and ISO-certified manufacturers it works with. Virtus tracks the factory batch number on every lot and catalogues it against independent lab testing, so each vial traces back to a specific, documented batch.

Every batch then passes multi-lab inspection, with the final Certificate of Analysis issued by ILS Laboratories, an ISO/IEC 17025 accredited US testing facility, covering purity, identity, quantitation, heavy metals, bacterial endotoxin, and a sterility screen.
Three vials per batch are tested, with quantitation and identity confirmed across the three to confirm batch conformity.

This network costs us more to source from.
We chose to pay it, holding the highest standard for the product and for our researchers.
