🔬 Peptide Purity Assurance
Nexara Labs – U.S. Manufactured Research-Grade Peptides
At Nexara Labs, purity is the foundation of every peptide we produce. All compounds are manufactured, filtered, and verified in a cGMP-compliant U.S. laboratory, using pharmaceutical-grade processes designed to exceed industry standards.
Our facility uses advanced purification, filtration, and analytical testing to ensure every batch meets the highest possible purity thresholds for research use.
⭐ Purity Standards
Every peptide is confirmed to be:
✔ 98–99%+ pure
✔ Free of contaminants, solvents, heavy metals
✔ Verified for identity and molecular sequence
✔ Tested for biological integrity and stability**
We use industry-standard purification methods including:
• HPLC (High-Performance Liquid Chromatography)
• Mass Spectrometry (MS)
• Amino Acid Sequencing Verification
• UV Spectrophotometry
These methods eliminate impurities and confirm the exact molecular composition of each peptide.
📄 Certificate of Analysis (COA)
Each batch is matched with an internal COA detailing:
• Purity %
• Molecular sequence confirmation
• Lot number
• Production date
• Analysis date
• Testing method (HPLC / MS)
This ensures complete transparency and traceability for research professionals.
🧪 U.S. Laboratory Manufacturing
All peptides are:
• Formulated and lyophilized in the United States
• Handled in sterile, controlled clean-room environments
• Packaged using medical-grade materials
• Stored under strict temperature and stability requirements
This ensures maximum stability, consistency, and reliability for laboratory research.
🛡️ Quality + Safety Guarantee

Nexara Labs stands by:
• Consistent purity across all batches
• Zero compromise in formulation or testing
• Pharmaceutical-grade handling and isolation protocols
Every peptide that leaves our lab is the result of careful engineering, meticulous quality control, and uncompromising standards.
