Certificates of analysis
Certificates of analysis, third-party lab tested by Titreon. Every batch, on the record.
Every Peptara Labs peptide is verified by Titreon Analytical, an independent laboratory whose quality system is aligned to ISO/IEC 17025:2017 (not itself accredited). Each batch is checked for purity by HPLC, identity by LC-MS, net peptide content, sterility, bacterial endotoxin, heavy metals, and fentanyl. Key batches also carry a second, independent bacterial endotoxin report from Janoshik, an analytical lab widely used for third-party peptide testing, and every certificate is downloadable.
What every certificate confirms
Identity by HPLC and LC-MS. Chromatographic purity against a not-less-than 95.0 percent release criterion. Net peptide content, sterility, bacterial endotoxin, heavy metal screening, and a fentanyl immunoassay. Across the current catalog, measured purity runs from 95.48 to 99.62 percent, and Janoshik independently reports bacterial endotoxin on the latest key batches.

Each certificate below is from a recent batch, issued by Titreon Analytical. Batches marked Janoshik also carry an independent bacterial endotoxin report. To match the exact batch you received, message us with your order number.
Why your vials arrive plain
Your vials ship unlabeled on purpose. Plain packaging keeps your order discreet in transit and at your door, and it is standard for research-grade material, not a sign that anything is off. Because there is no lot printed on the vial, the simplest way to tie your batch to its certificate is by order number: send us yours and the team will confirm the exact batch you received.
New to reading one of these? We walk through this exact BPC-157 certificate line by line in how to verify peptide purity, and the wider question of where to buy peptides covers what else to check on a vendor besides the testing.
Enter a lot number from any Peptara certificate or report. Vials ship unlabeled, so if you only have the vial, message us your order number on WhatsApp and we will confirm your batch.
