Purity tests alone cannot verify quality. Confidence comes from knowing exactly what is in every compound you use. At Licensed Peptides, we run 6 independent verifications on every batch through accredited laboratories. Each batch has a specific certificate of analysis (COA) for complete transparency, and our GMP-manufacturing standards ensure consistent batch-to-batch quality and reliability.

Our Quality Process
• We manufacture each research peptide in GMP-certified facilities in the U.S.
• We make each batch using validated manufacturing and quality control procedures.
• Our quality-control process helps identify issues in production before any batch is ready.
• HPLC analysis confirms the purity of each batch
• Mass spectrometry verifies the identity and structure of each peptide
• Separate screening for endotoxins, heavy metals, sterility, content, and visual inspections evaluates quality that purity testing alone cannot establish
• Every batch includes its own verifiable Certificate of Analysis (COA)
• Researchers can review purity, identity, and overall quality before ordering
• Full batch documentation provides complete transparency for researchers

Independent verification at every stage. Transparent results. No exceptions. Every lot is tested by third-party accredited laboratories before it leaves our facility.
High-Performance Liquid Chromatography confirms the compound makes up 99% or more of total content. No dilution, no shortcuts - the full separation profile is documented and published.
Confirms the exact molecular identity and sequence accuracy of each peptide. Protects against mislabeling and ensures you receive precisely what was ordered.
Limulus Amebocyte Lysate (LAL) testing detects bacterial endotoxins that cause immune reactions - even when the compound looks completely clean. Most suppliers skip this step.
Performed by an ISO/IEC 17025:2017 accredited laboratory. Confirms no viable microorganisms are present - going beyond sterile filtration alone.
Verifies the stated weight and concentration is accurate. Every milligram you receive is what the vial claims - no underdosing, no overpromising.
Visual inspection and lyophilization quality. Verifies proper freeze-drying, packaging integrity, and that no physical contamination occurred during production.
