The research peptide market has a documentation problem. Suppliers claim 99% purity; few prove it. Noxptide was founded on a simple principle: if a batch cannot be independently verified, it does not ship.
Every peptide is produced via solid-phase peptide synthesis (SPPS) and purified by preparative high-performance liquid chromatography. We do not release material below 99% purity — batches that fail are destroyed, not discounted.
Purity is confirmed by HPLC and molecular identity by mass spectrometry at an independent analytical laboratory. Verification happens outside our own facility, so the results you see are results you can trust.
Every order ships with a COA tied to your exact batch number — HPLC trace, MS identity confirmation and appearance testing. Request the current batch COA for any product before you order.
Lyophilised peptides are stored at -20°C, packed in sterile tamper-evident vials, and dispatched with full batch traceability from synthesis to your laboratory door.
| Test | Method | Acceptance Standard |
|---|---|---|
| Purity | High-Performance Liquid Chromatography (HPLC) | ≥99% |
| Identity | Mass Spectrometry (MS) | Matches theoretical molecular weight |
| Appearance | Visual inspection | White/coloured lyophilised powder as specified |
| Solubility | Solvent reconstitution test | Fully soluble in specified solvent |
Email us the product and we will send the current batch Certificate of Analysis during business hours. No account required, no obligation.
Send the product name and vial size so the current batch can be identified.
Confirm the batch number, HPLC purity, MS identity and appearance result.
Keep the COA with your records and confirm the vial batch number matches.
