Enter your reference compound lot/batch number to retrieve third-party independent HPLC purity analysis and Mass Spectrometry report certificates.
Like many premium research suppliers, batch/lot numbers are not printed directly on individual vial labels or boxes. Instead, Optima Peptide Lab maintains all master production batch records and 3rd-party independent HPLC & Mass Spectrometry certificates on file for every manufactured lot.
Enter a sample Lot ID below to view verification records (e.g., RET-2026-10A, BPC-2026-10, GHK-2026-50, NAD-2026-1000), or contact us for your specific batch file.
HPLC measures compound purity by separating organic molecules based on hydrophobic retention times. Every OptimaPeptideLab batch guarantees single-peak purity >99.0%.
Mass Spectrometry validates exact molecular weight (MW) in Daltons (Da) to confirm amino acid sequence accuracy and rule out sequence truncations.

This phrase is a quality-assurance claim stating that every manufactured batch of the peptide has been lab-tested and verified to contain at least 99% of the intended molecule, using industry gold-standard testing methods.
A "lot" (or batch) is a specific production run. "All lots" means every single batch manufactured undergoes testing, not just an occasional sample.
At least 99% of the peptide material present is the exact, full-length target peptide. The remaining <1% consists of minor synthesis byproducts (like truncated peptide chains or deletion sequences).
A separation technique that pumps the liquid sample through a column under high pressure. It physically separates the target peptide from impurities and measures purity percentage based on UV absorption peaks.
A detection method paired with HPLC that measures the exact mass-to-charge ratio (m/z) of the molecules. It confirms the chemical identity and exact molecular weight to ensure the peptide synthesized is actually the intended compound, not a lookalike.
Peptide synthesis is built step-by-step, amino acid by amino acid. Errors during synthesis can create incomplete chains or modified sequences. Pairing HPLC with Mass Spectrometry ensures two critical things: HPLC confirms how pure it is, and MS confirms what it is.
