Methodology
PiqBio-run independent Certificate of Analysis testing launches Q2 2026. Four panels, one signed COA, zero self-reporting. Once testing begins, every lot ships with a published COA and monthly releases open to the public.
The four-panel COA
Beginning Q2 2026, every research peptide will be tested by an independent US lab against four orthogonal panels. Results publish openly in the COA Library — nothing about the program is self-reported.
Reversed-phase HPLC quantifies the main peptide peak against impurities. We require ≥ 99% main peak or the batch is rejected. Gradient method and column reported on the COA.
ESI-MS confirms the molecular mass of the synthesized peptide against the theoretical value from the sequence. Identity is verified independently of HPLC retention.
USP <71> direct-inoculation sterility testing on each lot. Fluid thioglycollate and soybean-casein media, 14-day incubation. Result printed with the organism panel on the COA.
Limulus amebocyte lysate assay quantifies bacterial endotoxin in EU/mg. Lot-specific ceiling published on every COA — typically < 5 EU/mg, often < 1 EU/mg.
PiqBio-run independent Certificate of Analysis testing begins Q2 2026. Each month's lot releases will be published here, open to any researcher — no account, no paywall. The sample below shows the layout COAs will use once releases begin.
The data panel on the sample is an illustration, not a real lot. The first published COAs will replace it.

When the COA Library opens in Q2 2026, every analytical result will come from a third-party US laboratory. Self-reporting is not evidence; it's marketing with a pipette.
Batch-to-batch variance is real. The program will test every lot that ships — not a representative sample from last quarter. The lot on your vial will match the lot on the COA.
COAs will publish openly in our library the month the lot ships. If the paperwork doesn't hold up, the shipment shouldn't either. No hidden lots, no conditional release.
Analytical integrity is only useful if it survives transit. Our shipping protocol is designed to preserve the molecule, not just the box.
Peptides are lyophilized for stability and held at −20°C until packing. Lot-specific reconstitution and storage notes are provided on request.
Orders ship within 24 hours via 2-day ground carrier. Lyophilized peptides remain stable at ambient for typical transit. Insulated cold-chain packaging is available on request for climate-sensitive destinations or specific compounds.
Tamper-evident seals on every vial. Supplier specifications are on file now; signed COAs will be lot-matched in our public library once the Q2 2026 program opens. If the seal is broken on arrival, photograph it and we replace — no questions.
Next step
Tell us which compound you're evaluating. We'll send the on-file supplier specification now — and the signed PiqBio COA the month we start publishing, Q2 2026.
