About Sokai Sciences
Documentation first. Everything else follows.
Sokai Sciences supplies research-grade peptides to laboratories, institutions, and independent researchers who expect the same rigor from a supplier that they apply in their own work.
We started from a simple frustration: most peptide suppliers treat purity data and sourcing as an afterthought, buried behind marketing copy or withheld until you ask. We built Sokai Sciences to work the other way around — the specimen label comes first, and the sales pitch is optional.
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.
Purity, verified independently
Every batch is HPLC-tested by a third-party lab, not just our own QC process, with a certificate of analysis available on request.
Nothing behind the fold
Format, vial size, and purity are on every product page in the same place — no digging through FAQs or emailing to ask what's actually in the formulation.
Research use, stated plainly
These are laboratory research compounds, not consumer health products. We say so clearly and consistently, not as fine print to satisfy a requirement.
