Every batch Lone Star Peptide Co. ships is tested by an independent, accredited third-party laboratory. The complete documentation — HPLC chromatogram, mass spectrum, and endotoxin results — is accessible here by batch ID. No login required.
Enter the batch ID printed on your vial label to retrieve the Certificate of Analysis for that specific lot. The batch ID is printed on the vial in the format LSP-[COMPOUND]-[YYMM]-[REVISION].

Each synthesis run is assigned a unique batch ID at production. All vials from the same run share this ID, creating a traceable link from manufacture to your lab.
The batch is shipped to an accredited third-party laboratory for HPLC purity analysis, LC-MS identity confirmation, and LAL endotoxin testing. We do not test our own compounds.
The full COA — including chromatograms and spectra, not just summary numbers — is published here linked to the batch ID. No login. No request required. Permanently accessible.
What every field on a Certificate of Analysis means — purity thresholds, mass confirmation, what the chromatogram tells you, and red flags that indicate fabricated documentation.
Read the Guide →Why both tests are required, what each one measures, and how to interpret the results together. HPLC measures purity; mass spectrometry confirms identity. Neither alone is sufficient.
Read the Guide →What the LAL assay measures, acceptable EU/mg limits for cell-based assays, and why endotoxin contamination is the most common hidden confounding variable in peptide research.
Read the Guide →Why lot numbers matter, how to cite them in your methods section, and what a complete traceability chain looks like from synthesis through experimental use and publication.
