How we're different

Built for labs that don't
tolerate ambiguity.

Third-party verified

Every batch is independently tested by accredited third-party laboratories. The full COA is published publicly — purity, mass spec, contaminants. Nothing hidden.

Pharmaceutical-grade synthesis

Sourced exclusively from cGMP-certified facilities operating to ISO/IEC 17025. Every step from raw material to lyophilization is logged, batched, and auditable.

Verified batch identity

Every vial maps to a permanent batch page with chromatograms, purity metrics, and timestamped lab provenance so procurement and compliance teams can approve with confidence.

Radical transparency

We publish what
others hide.

Every batch we release ships with a public Certificate of Analysis from an independent lab. Purity. Mass spec. Contaminants panel. Nothing redacted. If we can't show it, we don't ship it.

From the lab

Researchers don't bluff.

"I've been buying reference compounds for fifteen years and Helix is the first vendor who actually publishes the chromatograms. That's the whole point."

"Dispatch timeline held to spec across two timezones. Batch identifier matched the COA and chromatogram exactly. Exactly what I expected to be table stakes."

"The QR-coded batch lookup is a tiny detail but it removes about an hour of administrative work per shipment for our compliance file."
