QUALITY & TESTING
Anyone can claim
purity. We publish it.
Every lot moves through the same pipeline before it reaches the catalog. Nothing lists until its certificate clears — and failed lots are rejected, not discounted.
01 · SOURCE
Compounds are produced by vetted manufacturing partners under documented process controls.
02 · ASSAY
Third-party laboratories run purity and identity on every lot. We don't grade our own work.
03 · RELEASE
Pass the spec, the certificate publishes and the lot lists. Miss it, the lot never ships.
04 · TRACE
Your lot number resolves to its certificate for good — in the register and in your account.
