Lab-Tested Peptides (COA)

Lab-tested peptides with a certificate of analysis (COA) are the products in our range for which independent test results are on file and batches are documented. A COA shows the identity and purity of a specific batch. For research, this is the difference between assuming what is in the vial and knowing it. This category lists every product with COA documentation.

Lab-tested peptides in this category

• GLP-3RT: 13 batches documented, our most tested product
• BPC-157 / TB-500 blend 10/10 mg: 6 batches documented
• TB-500 10 mg: 6 batches documented
• GHK-Cu 50 mg: 6 batches documented
• NAD+ 500 mg: 6 batches documented
• GLP-2T: 2 batches documented

What a peptide COA tells you

A certificate of analysis for a peptide normally contains two core results. Mass spectrometry confirms the identity: the measured molecular mass must match the expected mass of the sequence. HPLC measures the purity: the percentage of the peptide in the sample compared to impurities such as shortened sequences. A complete COA also names the batch number, the test date and the laboratory. Our Lab Handbook explains in detail how to read a peptide COA and what peptide purity by HPLC and mass spectrometry means.

Why batch documentation matters for research

Peptides are synthesised in batches, and each batch can differ slightly in purity and water content. When several batches of a product are documented, you can see how consistent the supplier is over time. For GLP-3RT with 13 batches, this record is the longest in our range. For the repair peptides TB-500 and the BPC-157 / TB-500 blend, six batches each are on file.

Products without COA in our range are not untested, but the documentation is not yet complete. We extend this category as further batches are tested. The full range is listed under all research peptides.

Research use only

A COA confirms identity and purity of a research compound. It does not make the compound an approved medicine. All lab-tested peptides are sold for laboratory research use only and are not intended for human or veterinary use.
