Sokai Sciences is a U.S.-based company. We don't add a compound to the catalog just because a supplier is willing to sell it to us — every source is vetted before it's carried, and every batch still goes to an independent lab for HPLC verification regardless of who made it. That's the difference between a vendor and a supplier you can actually rely on.

The catalog itself is built with intent. Rather than stocking the handful of compounds every site already carries, we set out to cover the range a working lab actually needs — established names alongside newer research compounds, chosen deliberately rather than added because they were easy to source. And every listing still gets the same documentation: purity verified by an independent lab, format and vial size disclosed up front, nothing you have to email to find out.

Stock is also chosen with the bench in mind: where a compound comes in multiple strengths, we lean toward the higher-concentration vial rather than the smallest one. A single stronger vial gets you more usable doses than reconstituting several smaller ones — less bacteriostatic water, less waste, fewer vials to keep track of.

Sokai Sciences is one of two disciplines under the Sokai name, alongside Sokai Labs. One origin, two focuses: Labs formulates everyday wellness supplements, and Sciences supplies research-grade compounds for laboratory use. Separate catalogs, separate standards for what each requires — the same commitment to documenting exactly what's in the vial.
