Issuing lab, lot & accessionOn the certificate

Per lot, not per vial. Ask for the lot you are being quoted — it is sent before you spend. Our own lots carry all five measures; supplier lots carry three, and we tell you which is which.

Check it yourself. Send a vial to any accredited lab and compare their number to ours.

Not claimed: sterility and heavy metals. We do not test for them and will not say we do.

05Questions

what buyers ASK FIRST.

Everything we supply is for laboratory research only. Nothing in the catalog is a drug, a food, a cosmetic or a dietary supplement, and nothing is intended for human or veterinary use. Buyers confirm that at account setup and we decline orders that suggest otherwise. It also binds how you sell: your labels and your store cannot make human-use, dosing or benefit claims.
Because the book is not public. Pricing sits inside the portal, set per account and quoted by a person. Request access and you see live numbers on every product before you commit to anything.
No. Wholesale starts at one case and the price is the same whether you buy one or fifty. White label is billed per vial actually shipped, so you are not buying inventory you have not sold.
Two ways, and you should use both. Ask us for the certificate covering the lot you are being quoted — it names the issuing lab and carries the accession number. Then send a vial from your own order to any accredited lab you choose and compare.
Yes — that is the white-label lane. Send us your brand name and artwork, we print matte waterproof labels and apply them to stock held in your name in Los Angeles. Required research-use wording stays on the label.
Research organisations, laboratories, clinics and research-use-only brands. We are business to business only — individual retail buyers are declined. Every request is reviewed by hand before your first invoice.
