Frequently Asked Questions
Everything you need to know about our research-grade peptides, testing standards, and ordering process.
Yes. Every single batch is sent to an independent, accredited laboratory for HPLC and mass spectrometry analysis. We publish the results publicly — no hidden reports, no selective sharing.
We guarantee a minimum of 99% purity on all compounds. If a batch doesn't meet our threshold, it never ships.
If purity falls under 99% — which is highly unlikely and an extremely rare occurrence — we will offer the batch at a heavily discounted price. Full transparency on the COA always comes first, and you'll know exactly what you're getting before you order.
All orders ship in plain, unmarked packaging with no external branding. We try to dispatch orders same-day, but at most they will be dispatched within 48 hours.
No. All products sold by NA Peptide are strictly for laboratory research and development purposes only. They are not intended for human consumption, therapeutic use, or diagnostic applications of any kind.
Every product page includes a link to the corresponding Certificate of Analysis. You can also browse our full COA library at any time — no account required. Each certificate includes batch number, purity percentage, mass, and testing methodology.
Due to the nature of research compounds, we cannot accept returns once vials have been opened. If your order arrives damaged or incorrect, contact us within 48 hours and we will replace it at no cost. Full details are available on our Return & Refund page.
No. Lyophilized peptides are stable at all shipping temperatures and do not degrade. Temperature-controlled shipping is not required for freeze-dried powders. It is a myth.
