Confidence Starts with Transparency.
Nothing goes on sale on the strength of a supplier's word. Every lot moves through the same four checks, and the certificate for that exact batch is published before the product page goes live.
Four Checks Before a Lot Becomes a Listing
Each step has to pass before the next one starts. What the instruments measure is what appears on the certificate, and the certificate is what appears on the product page.
Intake & Identity
Mass spectrometry confirms the compound is what the supplier says it is before anything else is measured. A mismatch ends the lot here — it is never listed, and it never enters inventory.
Purity by HPLC
Reverse-phase HPLC runs the material against a reference standard. The measured figure is what we publish — not a rounded marketing number — so you can compare it with your own results.
Second-Lab Confirmation
The retained sample goes to an unaffiliated lab that has no stake in the result. Both certificates are published side by side, so the check is visible rather than asserted.
Lot-Linked Publication
The lot number printed on your vial resolves to one certificate — no generic document standing in for a batch. It stays searchable publicly and archived against the orders in your account.
What Every Certificate Carries
Certificates are tied to the batch you receive, not to the product in general. Search a lot number to read the paperwork before you buy, or pull it from your order history afterwards.

FAQ
Is Every Lot Really Tested?
Yes. Identity is confirmed by mass spec and purity by reverse-phase HPLC, and a retained sample goes to a second, unaffiliated lab. Both certificates are published against the lot number before the product page goes live.
How Do I Find the Certificate for My Vial?
Enter the lot number printed on the vial label into the COA lookup. The same certificate is archived permanently in your account after purchase.
How Fast Do Orders Ship?
Completed, fully paid orders ship within one business day from our U.S.-based fulfillment center, USPS with tracking. Expedited options are available at checkout for an additional fee.
Is the Packaging Discreet?
Yes — plain, unbranded, tamper-evident outer packaging. Nothing on the outside identifies the contents or the sender category.
How Should Material Be Stored?
Compounds ship as lyophilized powder, shelf-stable and sealed, so no cold chain is required in transit. For long-term storage keep lyophilized at −20°C away from light.
Can These Be Used in Humans or Animals?
No. Everything sold here is strictly for in-vitro laboratory research. These are not drugs, foods, cosmetics or supplements, and are not for human or veterinary use.
Read the Paperwork, Then Decide.
Every listing links to the certificate for the lot in stock. If a lot doesn't match its certificate, we replace it or refund it.
