Third-Party Lab Reports
Published laboratory reports provided by our supply partners Baltic Peptides and Particle Peptides. Compare the measured results for each identified sample.
Baltic BioLabs is an independent research peptide shop in Vilnius, Lithuania, at balticbiolabs.eu. Our catalogue brings together vial sizes, prices, published third-party batch reports and delivery information. Today orders are fulfilled by the named suppliers: Baltic Peptides (balticpeptides.com), code balticbiolabs10 for 10% off, and Particle Peptides (particlepeptides.com), code BALTIC10 for 10% off. These are separate companies with separate websites. The reports below identify a sample batch and report date. Methods differ, including HPLC, LC-MS and content or pH measurements; read the result with its method. How Baltic BioLabs and Baltic Peptides relate.
New to certificates of analysis? Our guide to reading a peptide COA explains HPLC purity, mass-spec identity, and the red flags of a weak or fake COA.
How These Compounds Are Tested
Check which analyses the laboratory performed on the submitted sample. A report may include some of the following measurements; they answer different questions.
HPLC Analysis
Reports chromatographic peak-area purity under the stated method. This does not by itself measure the peptide mass in a vial or all possible impurities.
Mass Spectrometry
A matching intact molecular mass supports identification. It does not alone establish amino acid order or stereochemistry; check the specific analysis performed.
Endotoxin Testing
Measures bacterial endotoxins under the stated test method and limit. It is a separate analysis and does not establish general sterility.
The PDFs below are the documents published for these samples. Check the laboratory, sample identifier, date and stated analyses. Match the offered supplier, size and batch with the document before ordering.

Not sure what to look for in one of these?How to read a peptide COA walks through a real certificate line by line: which purity figure counts, how the mass-spec result confirms identity, and the signs of a weak or fabricated report.

What "Research-Grade" Means Here
Compounds linked here are supplied as laboratory research materials. These reports describe the submitted samples and their measured results; they do not authorise a commercial reagent for clinical use or establish that every vial or later batch has the same results.
