Documented purity from
a source you can trace.

Research is only as good as the material it's built on. A result is meaningless if you can't trust what was in the vial. That's the gap Onyx was built to close — every lot we sell is independently assayed for purity by reverse-phase HPLC and confirmed for identity by mass spectrometry before it's ever listed.

We don't grade our own work. Testing is done by an independent laboratory, the certificate is archived against a unique lot ID and lives in your account. If you can't document it, it's not worth selling.

Compounds are produced to a defined specification, lyophilized to a shelf-stable powder, and sealed against light and moisture — no cold chain required. Orders are picked, sealed, and dispatched the same or next business day in plain, unbranded, tamper-evident packaging, tracked to your door.

For labs, clinics, and resellers, we run standing orders at volume pricing with bulk COA documentation and net terms — the same rigor, at scale.

Everything Onyx supplies is intended strictly for in-vitro laboratory research and development. Our products are not drugs, foods, cosmetics, or supplements, and are not intended to diagnose, treat, cure, or prevent any disease. They are not for human or veterinary consumption. By purchasing, you confirm you are a qualified researcher handling these materials in an appropriate setting.
