Every lot, tested and documented.
Reproducible research starts with knowing exactly what is in the vial. Here is how we verify identity and purity — and what ships with every order.
The process
Every compound we sell is verified on two independent axes before it reaches a researcher — how pure it is and whether it is what the label says:
- HPLC purity analysis. High-Performance Liquid Chromatography separates a sample into its individual components, quantifying the target compound against any impurities. Our materials are tested to 99%+ purity.
- Mass-spectrometry identity verification.MS measures the molecular mass of the compound and confirms it matches the expected sequence — the check that the vial contains the correct molecule, not a look-alike.
- Independent, third-party labs. Testing is performed outside our own walls, which is what makes a purity figure something a lab can actually cite in its documentation.
What ships with every order
Each order includes a lot-specific Certificate of Analysis— the document that ties the tested purity and confirmed identity to the exact production lot you received. If you are comparing suppliers for any research peptide, a current, lot-specific CoA (not a generic marketing claim) is the baseline a serious lab should expect. It is also what makes your own results reproducible: you can point to precisely which material was used.
For laboratory and research use only
Rigorous testing documents what a compound is— it does not make a research compound a medicine. Every product we sell is for laboratory and research use only. It is not FDA-approved, not a dietary supplement, and not intended to diagnose, treat, cure, or prevent any disease, or for human consumption.
Frequently asked questions
What is a Certificate of Analysis (CoA)?
A Certificate of Analysis is a lab document that reports the tested purity and confirmed identity of a specific production lot. It is the primary way a researcher documents exactly what material was used in their work.
How is purity measured?
Purity is measured by High-Performance Liquid Chromatography (HPLC), which separates a sample into its components so the percentage of the target compound versus impurities can be quantified. Our compounds are tested to 99%+ purity by HPLC.
How is identity confirmed?
Identity is confirmed by mass spectrometry (MS), which measures the molecular mass of the compound and verifies it matches the expected sequence — so you know the vial contains what the label says.
Is testing done in-house?
Analytical testing is performed by independent third-party laboratories, which is the standard that makes a result credible and reproducible for research documentation.
