Compounds engineered
for the researcher
who refuses to guess.
Every batch tested. Every certificate public. Zero compromises.
Built for labs that don't
tolerate ambiguity.
Third-party verified
Every batch is independently lab tested by Janoshik Analytical or Auxilium Pharma Labs. 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.
Cold-chain shipping
Temperature-controlled from synthesis to your door. Vacuum-insulated containers with phase-change coolants sized to your shipment weight and destination climate.
Currently in stock.
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.
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."
"Cold-chain held to spec across two timezones. Batch identifier matched the COA matched the chromatogram. 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."
