The compounds with the highest reorder rates in our catalog. Each one carries at least two published lots so you can compare batch-to-batch consistency, not just read a single flattering certificate.

Why the certificate matters
The gap between a supplier who tests and a supplier who says they test is invisible at the point of sale — which is exactly why we made every lot record public and searchable before you spend anything.
RP-HPLC for purity and ESI LC-MS for identity on every lot, plus a third assay where the compound has a known failure mode.
The certificate you read is the certificate for the vial you receive. Look it up by lot number before you order, not after.
Release testing is run by ISO/IEC 17025 accredited third parties. We publish their name and accreditation, not just a number.
LAL endotoxin quantified in EU/mg and USP <71> sterility on every lot, with the measured figure reported — not just a pass.
Lyophilised at -20 °C, held at -20 °C, shipped in an insulated cold pack. Storage conditions are on the certificate.
Orders placed before 1:00 PM PT on a business day leave the same day, tracked, from our Reno facility.
How it works
The whole point of lot-level verification is that it works adversarially. You should be able to check a Certus vial against a Certus certificate without taking a single claim on this page at face value.
Verify a lot nowEvery label carries a code in the form CP-COMPOUND-YYMM plus a run letter. It is printed, not stickered on afterwards, and it is unique to one synthesis run.
The lot resolves to its own page with the full assay panel — method, specification and measured result for each line, plus the testing laboratory and its accreditation number.
Not just the purity figure. Net peptide content governs your concentration; endotoxin governs whether the material is usable in cell culture. Both are on the certificate, with the measured value rather than a pass mark.

Latest releases
A running ledger of every batch that passed release. Retired and superseded lots stay listed — an archive that only shows current stock is a catalog, not a record.

From the bench
“The first supplier I have used where the COA line items actually match what I would run myself. Net peptide content on the label instead of cake weight saved me a re-titration.”
Analytical chemist

“We buy the same compound quarterly and I compare lot certificates side by side. Batch-to-batch variance has been under half a percent, and the archive makes that checkable rather than something I have to take on faith.”

“Endotoxin reported as a measured figure rather than a pass mark is the detail that won me over. In cell culture that number is the difference between a clean result and a confound.”

Still unresolved? Talk to someone who works in the lab — not a chat queue.
Every vial we ship carries a lot number on its label. That code resolves to one batch record on this site, with the full assay panel for that specific run — not a representative sample from a previous batch. You can look up any lot before you order, which is the point: verification is only a trust signal if it works before you have spent anything.
Independent laboratories accredited to ISO/IEC 17025. The testing laboratory's name and accreditation appear on each certificate rather than a generic 'third-party verified' badge, because a badge you cannot check is not evidence.
No, and we would rather say so. HPLC purity is an area-percent measurement of UV-absorbing species — it does not tell you how much peptide is in the vial. That is net peptide content, which we report separately and use to label vial strength. A 10 mg vial contains 10 mg of peptide, not 10 mg of cake.
No. Everything we sell is supplied strictly for laboratory research use. These are not drugs, supplements or medical devices, they have not been evaluated by the FDA, and they are not intended for human or veterinary administration of any kind. We are a research chemical supplier, not a compounding pharmacy.
Lyophilised, in an insulated cold pack, tracked, by UPS or FedEx from our Mount Pleasant, SC facility. Orders ship once payment is confirmed. Free cold-chain shipping over $200.
Send us the lot number and we will replace the order and pull the batch while we investigate. That commitment is only meaningful because the certificate is public and specific enough to check us against — which is exactly why we publish it that way.
