How to Avoid Counterfeit Peptides: A Buyer's Guide for UK Laboratories
The Counterfeit Peptide Crisis
The booming global interest in research peptides has driven an influx of low-grade, under-dosed, or completely fake compounds into the market. Buying from unverified sources not only wastes research funds but can introduce harmful contaminants like heavy metals or bacterial endotoxins into delicate assay systems.
How to Verify Peptide Authenticity
- Analyze the HPLC Graph: High-Performance Liquid Chromatography measures the purity of a compound. Look for a single, tall, narrow peak on the graph. Multiple peaks indicate chemical impurities or degradation products.
- Check the Mass Spectrometry (MS) Data: Mass spectrometry confirms the identity of the peptide by measuring its precise molecular weight. The primary peak on the MS chart must match the theoretical molecular weight of the peptide sequence.
- Verify the Laboratory: Ensure the Certificates of Analysis (COAs) are issued by reputable, independent, third-party laboratories. Be suspicious of COAs with redacted testing dates or names.
