At Loti Labs, we believe trust is built through openness. That’s why we publish Certificate of Analysis (COA) reports for each batch we produce— showcasing purity, potency, and safety. Browse, download, and verify — your confidence is our foundation.
Search every current peptide certificate by product name, testing date, batch ID, laboratory, or analytical method. Each record keeps its permanent archive copy and laboratory source when available.
54 current peptide certificates. Most recent test: Oct 15, 2026. Showing the current batch for each product. Earlier batches (15) stay in the full COA archive.

Purity (RP-HPLC) is the share of detected material that is the target compound. Content (HPLC quantitation) is the measured amount of that compound in the tested vial, in mg. A sample can show 99.9% purity and still measure above or below the labeled amount, so both numbers are published exactly as the laboratory printed them.
Identity is confirmed by mass spectrometry (MALDI-MS or LC-MS). The molecular weight shown on each record is the value printed on the laboratory report.
If your vial label shows a lot number, search it above. Every record lists the lot printed on the laboratory report. When a report did not print a lot number, the record is listed under its laboratory verification code and the batch field reads "Not printed on report."
Where available, the laboratory link opens the copy hosted by the testing laboratory. The archive image is the certificate as Loti Labs received it. Questions about a specific record can be sent to our team through the contact page.
All certificates of analysis on this website are intended strictly for research and laboratory use only. None of the products referenced are intended for human or animal consumption.
