Batch-Tested · Third-Party Verified
Don't trust the label.
Trust the certificate.
Every batch is sent to an outside lab for purity and identity testing before it ships. The code on your vial pulls up the result that batch actually produced — not a number we printed.

Our standard
Purity isn't a claim
on our label. It's a number
on your screen.
Most suppliers ask you to take their word for it. We'd rather you check. Each label carries a batch code that traces to a real chromatography result — synthesis date, purity percentage, and testing lab — sent to you on request.
How verification works
Three checks, before anything ships.
Traceability isn't a marketing line here — it's the order of operations for every batch we release.
Shop the catalogSynthesis & in-house QC
Each peptide is synthesized to spec and screened in-house before it's cleared for third-party review.
Independent lab analysis
A sample from every batch is sent to an outside diagnostics lab for HPLC purity and mass spec identity testing.
Vacuum-sealed & logged
Vials are vacuum-sealed, labeled with a batch code, and logged for traceability — the Certificate of Analysis is available on request.
About Pivotal Biolabs
Built for researchers who ask for the data.
Pivotal Biolabs started as a reaction to a market where "premium" is a word on a label, not a number in a report. We work with one synthesis partner and one outside testing lab so every batch follows the same chain of custody, start to finish.
Every compound we carry is sold strictly for laboratory research — not for human or veterinary use — and every vial ships with a batch code you can look up yourself, any time, before you open it.
