01Purity
99.6%+ peptide content
Every compound is synthesized and analyzed to pharmaceutical-grade tolerances. If a batch doesn't clear 99.6% on HPLC, it doesn't ship.

Quality standard
Why research-grade?
Research-grade isn't a marketing label. It's a measurable quality tier with a purity floor, independent verification, and documentation you can audit. Here's what it means at Axios, and why it matters for your work.
What it means
A measurable tier, not a label.
Most peptides sold online are manufactured for one thing: margin. That means 70–85% purity, no published analysis, and no traceability. For a research application, that's a broken variable.
Research-grade targets the opposite: the 99.6%+ HPLC purity floor that pharmaceutical manufacturing runs on, with an independent Certificate of Analysis attached to every batch so you never have to take anyone's word for it.
One batch, one COA, one stable compound going into your experiment.
The four standards
How we define research-grade.
02Verification
Third-party COA on every batch
Independent American labs run the analysis. Certificates of Analysis are published per batch and downloadable from the product page.
03Manufacturing
cGMP-certified facilities
All synthesis happens in FDA-audited, current Good Manufacturing Practice facilities under documented quality-control protocols.
04Handling
Cold-chain packaging
Orders ship in temperature-controlled mailers so peptide stability is preserved from fill-line to your bench.

Common questions
Quick answers.
What does “research-grade” actually mean?
Research-grade is a higher quality tier above typical consumer-grade chemicals. It targets pharmaceutical-level purity, requires independent analytical testing, and ships with documentation a researcher can audit. Axios manufactures above the 99.6% HPLC purity threshold.
How is this different from consumer peptides?
Consumer peptides typically lack published COAs, aren't made in cGMP facilities, and use loose purity claims. Research-grade batches are tested by an independent lab, have full traceability, and ship with the analytical documentation.
Can I see a COA before I buy?
Yes. Every product page links to the Certificate of Analysis for the current batch. You can also download historical COAs from our certificates library.
Is this for human use?
No. All products are sold strictly For Research Use Only and are not intended for human or animal use, diagnosis, or treatment.
Work on compounds you can trust.
Every Axios batch ships with an independent Certificate of Analysis. Browse the catalog or review the current COA library.
