Precision for the work that matters.
Research compounds sold by the lot. No lot goes on sale until its certificate of analysis is published — for qualified laboratory and analytical work.
For Research Use Only
A document is a claim. We treat it that way.
Research supply is crowded with confident language and thin evidence — premium, pharmaceutical-grade, guaranteed, ultra-pure — almost none of which survives a question about documentation.
King Biologix takes the opposite position. Every lot is tested before it goes on sale, its certificate is published against its lot number, and nothing is sold ahead of that record. Where a figure is not yet documented, we mark it as such rather than round it into confidence.
Five rules we hold
Bought by the lot
Material is bought and tracked by the lot. The lot is the unit every record, label and certificate is tied to.
Tested before release
Each lot is sent for analysis before it goes on sale. Its certificate states the laboratory, the methods and the test date, so you can judge it yourself — we do not summarise it into a grade.
No certificate, no sale
A lot is released only when its certificate is on file and published in the COA lookup. Until then the product shows “COA pending” and cannot be ordered.
Lot number on every vial
Every vial label carries its lot number, and that number resolves to the lot's certificate in the public lookup.
Nothing stated that a certificate doesn't support
No purity figure, grade or certification appears on this site unless the certificate for that lot supports it. Where a figure is not yet documented, it is marked as such.
Raising the standard for how research compounds are presented.
King Biologix exists to raise the standard for how research compounds are presented, documented, and supported. Our position is structural, not cosmetic: state precisely what is known, mark plainly what is not, and let the documentation carry the argument.
Evidence before adjectives
A specification we cannot evidence does not appear. Unsubstantiated figures are marked, not rounded into confidence.
Documentation as product
The analytical record is not paperwork attached to a material — it is half of what a research supplier sells.
A boundary we hold
We supply materials and records. We decline to supply preparation, protocol, or use guidance, and we do not make exceptions.
Legible limits
Pending records and unavailable material are shown rather than hidden. The uncomfortable states are the informative ones.
Access is granted to qualified researchers.
Our catalogue of research compounds opens to qualified researchers who accept our Research Use Policy. Request access and we'll notify you the moment it does.
