We don't ask you to trust us blindly. Every PEPTARA Health product is independently tested by a certified laboratory, with documentation available on request.
Our quality assurance process is designed to eliminate uncertainty at every step — from synthesis to your lab.
All peptides are synthesised at GMP-certified facilities using solid-phase peptide synthesis (SPPS) under controlled conditions.
Before submission to third-party testing, each batch undergoes an initial quality control review at the synthesis facility.
Samples are submitted to a certified, independent third-party laboratory for HPLC and mass spectrometry analysis.
Only batches that meet our >99% purity threshold receive a COA and are approved for inventory and shipment.
Our testing protocols are designed to verify every critical quality parameter for research-grade peptides.
High-Performance Liquid Chromatography (HPLC) is used to measure the purity percentage of each compound, ensuring all products meet our minimum >99% threshold.
Mass spectrometry confirms the molecular weight and identity of each peptide, verifying that the correct compound has been synthesised with the expected structure.
Select products undergo sterility testing to confirm the absence of microbial contamination, critical for maintaining the integrity of lyophilised research compounds.
Water content analysis ensures that peptide powders meet required moisture specifications for long-term stability during storage and shipping.
For complex peptides, amino acid composition analysis confirms that the sequence and ratio of amino acids matches the expected molecular profile exactly.
Residual solvent levels are tested to ensure compounds are free from synthesis byproducts or organic solvents that could compromise research results.
COA documents are available for every product and batch. Fill in the form or contact us directly.
A Certificate of Analysis from an independent laboratory provides verified documentation for your research records.
