What we hold every batch to
The floor is fixed: no batch is released below 99% purity by HPLC, and no batch is released without identity confirmation by mass spectrometry. Purity says how much of the sample is one substance; identity says which substance. Both lines appear on every certificate, because either alone is half an answer.
Documentation is per production lot, not per product line. Two orders of the same compound from different batches carry different certificates with different lot numbers, and the lot number on the paper matches the lot number on the vial in your hand.
None of this is exceptional laboratory practice, it is ordinary laboratory practice, applied without exception. What is unusual in this market is not the standard but the willingness to be checked against it, which is what the rest of this page invites you to do. Who stands behind the standard, and where the company is registered, is set out on the about page.
Peptide quality control, as we use the phrase, ends at the release decision: a batch either meets the specification or it does not ship. The certification of the producing facility describes the management system around that decision, the ISO 9001 page sets out what such a system has to document, while the certificate describes the measurement itself. Neither replaces the other, and neither replaces your own look at the vial on arrival, for which the degradation page lists the visible signs.

What our standard does not claim
A certificate describes chemistry, not biology. It tells you the compound is present, pure and correctly identified; it says nothing about what the compound does, because that is the literature’s job, and where the literature is thin, our compound pages say thin.
We also do not claim pharmaceutical GMP status. Research-grade and medicine-grade are different regimes, and a supplier who blurs them is overselling. What we claim is exactly what we document: identity, purity, per-batch traceability, and a complaints process with teeth.
Finally: our own paperwork should not be exempt from the scepticism we teach. The buying guides on this site apply to us in full, and the fake-COA checklist was written to survive being run against our own certificates. Run it.
- 99% HPLC floor, every batchNot a catalogue average, not a best case. A release threshold with a paper trail.
- Identity by mass spectrometryThe line that outranks purity, present on every certificate we issue.
- COA before payment, on requestName the product, we name the batch and send the document.
- Condition-on-arrival guaranteeDamaged or suspect on delivery: report it and we resolve it via the complaints process.
