Old Lab-Tested COAs

For peptide products used only for research purposes (not for human or animal consumption), there are certain Quality and Certificate of Analysis (COA) standards that are important to adhere to in order to ensure the integrity and reliability of the product for scientific studies. Here’s an overview of the key aspects you might consider for your peptide product’s quality and COA standards:

Quality Standards for Research Peptides:

  1. Purity: ≥95%, tested by HPLC, with impurities below 5%.
  2. Identification: Confirm sequence using MALDI-TOF or LC-MS.
  3. Sequence Verification: Ensure 100% sequence accuracy via mass spectrometry.
  4. Solubility: Ensure peptide dissolves in intended solvents; typically ≥1 mg/mL.
  5. Residual Solvents: Levels must be below regulatory limits, tested by GC.
  6. Endotoxin Levels: ≤0.1 EU/mg, tested via LAL Assay.
  7. Water Content: ≤5%, tested by Karl Fischer Titration.
  8. Stability: Peptide should remain stable with minimal degradation over time.
  9. Heavy Metals: Levels should be ≤0.1 µg/g for lead, mercury, arsenic, and cadmium.
  10. Packaging and Storage: Store in airtight, light-resistant containers at -20°C to -80°C.
  11. Microbial Contamination: Should be free from microbes, tested for sterility.

These standards ensure peptides are reliable, safe, and suitable for research.

Certificates of Analysis (COAs)

Unique Batch Identifier

Each product is assigned a unique batch identifier to ensure full traceability, authenticity, and quality control across every stage of production and testing.

Batch-Specific COAs

Every batch includes a dedicated Certificate of Analysis (COA) to verify purity, quality, and third-party testing results for complete transparency and trust.

No Generic Documentation

All documentation is batch-specific and product-specific, ensuring precise verification with no generic or duplicated reports—only accurate, traceable data for every product.
