Every batch independently analysed by accredited laboratories. You get the results - we publish them openly.
High Performance Liquid Chromatography confirms purity to 0.1% resolution.
MS confirms the exact molecular identity and sequence of every peptide.
Testing performed by labs with no commercial relationship to our supplier.
We do not rely solely on supplier certificates. Every product batch we receive is sent to an independent, ISO-accredited laboratory for full analytical characterisation before we ship a single unit.
| Test | Method | What It Confirms |
|---|---|---|
| Purity | HPLC (≥99%) | No impurities above 0.1% |
| Identity | Mass Spectrometry (MS) | Correct molecular weight and sequence |
| Appearance | Visual inspection | White to off-white lyophilised powder |
| Moisture content | Karl Fischer titration | Residual water within specification |
| Microbial | USP <61> | No bacterial or fungal contamination |
Manufacturer-issued certificates of analysis have an inherent conflict of interest - the manufacturer is testing their own product. Independent lab testing removes this bias.
