How to Verify a Peptide Certificate of Analysis
A COA is only as useful as your ability to read it. A field guide to identity, purity, mass confirmation and batch traceability — and the red flags that should stop an order.
Synthesized in domestic laboratories
Verified by third-party HPLC & MS
Batch-specific documentation on file
Temperature-conscious, tracked dispatch
Registered access
Our full range of research compounds — specifications, batch documentation and pricing — is shown to registered researchers only. Registration takes under a minute, and access is immediate: no approval queue, nothing to confirm by email.
How it works
Choose a compound and open its batch Certificate of Analysis before you order. Every purity figure is documented, never asserted.
A quiet, single-page checkout. Confirm qualified-researcher status, and your order is logged against its batch record.
Lyophilized vials leave our US facility within one business day, tracked and packed for transit stability.
Why auraa
We source domestically and document obsessively. The result is a short, legible chain between synthesis and your bench — and paperwork that stands up to scrutiny.
Compounds produced in US laboratories with recorded provenance for every batch.
Third-party HPLC and mass spectrometry — the chromatogram travels with the number.
Every vial ties to a lot number and a retrievable Certificate of Analysis.
Lyophilized material packed for transit stability and dispatched within a business day.
Marketing language is free. Documentation is expensive. We invest in the paperwork.
Research guides
Procurement, documentation and storage — the research and quality-assurance side of the field.
A COA is only as useful as your ability to read it. A field guide to identity, purity, mass confirmation and batch traceability — and the red flags that should stop an order.
Lyophilized and reconstituted peptides have very different stability envelopes. Temperature, light, moisture and freeze-thaw cycles — how each affects a research sample, and how to log them.
Sourcing, testing transparency, documentation, and logistics. A framework for evaluating a research-compound supplier on evidence rather than marketing.
