The BioStem standard

Four commitments that apply to every vial we ship, without exception.

Testing & documentation

Testing is the trust signal

In a market where quality is hard to verify, the only meaningful answer is paperwork. Every BioStem batch is submitted for independent third-party analysis, and the resulting certificate is tied to the specific lot number printed on the vial you receive.

You should be able to review exactly what you ordered before it reaches the bench — not after.
