Purity is the single most important factor in research peptide quality. Peptides Pharma maintains >99% purity across all products, verified by independent third-party testing. This FAQ explains our quality assurance processes.
All Peptides Pharma peptides are manufactured to >99% purity. This exceeds the standard threshold for pharmaceutical-grade classification and ensures minimal impurity content that could affect research outcomes.
Peptides Pharma uses High-Performance Liquid Chromatography (HPLC) as the primary purity testing method, supplemented by mass spectrometry for identity confirmation, endotoxin testing, and amino acid analysis. These represent the gold standard for peptide quality control.
A CoA is an official document reporting quality testing results for a specific production batch. Peptides Pharma CoAs include purity percentage (HPLC), molecular weight confirmation, appearance, solubility, endotoxin levels, and sterility results.
Peptides Pharma peptides are manufactured in GMP-certified facilities meeting ISO 7 cleanroom standards. GMP ensures standardised processes, quality control, and traceability.
0.22 micrometre membrane filtration is a sterilisation method that removes bacteria and microorganisms from liquid solutions. All Peptides Pharma peptide solutions pass through 0.22um filters during manufacturing.
Gamma ray sterilisation uses ionising radiation to destroy microorganisms including bacteria, viruses, and fungi. Peptides Pharma vials undergo gamma ray sterilisation as an additional sterility measure beyond 0.22um filtration.
Impurities including truncated sequences, oxidised forms, and residual solvents can produce off-target biological effects, reduce potency, introduce confounding variables, and compromise reproducibility. >99% purity minimises these risks.
Every Peptides Pharma product comes with a batch-specific Certificate of Analysis. Request the CoA for your specific batch by contacting info@peptidespharma.com with your order number and batch code.
Peptides Pharma tests for truncated peptide sequences, deletion peptides, oxidised variants, residual solvents (TFA, acetonitrile), heavy metals, endotoxins, and microbial contamination.
Yes. Every production batch is submitted to independent, accredited third-party laboratories for verification testing. Third-party results are included in the Certificate of Analysis.
