Q: What purity standards should research peptides meet? A: Research-grade peptides should have minimum 98% purity verified by HPLC analysis, with molecular identity confirmed by mass spectrometry. Always request batch-specific Certificates of Analysis (COAs) from independent third-party laboratories. Avoid suppliers who cannot provide current COAs. Q: How should research peptides be stored? A: Store lyophilized peptides at -20C protected from light and moisture. Reconstituted solutions should be refrigerated at 2-8C and used within 14-21 days. Use bacteriostatic water for reconstitution. Never refreeze reconstituted solutions. Q: How do I read a Certificate of Analysis (COA)? A: A valid COA should include: the peptide name and batch number, HPLC purity percentage (98%+ target), mass spectrometry confirmation of molecular weight, endotoxin testing results, the laboratory name and accreditation, and the date of analysis. Third-party COAs are more reliable than manufacturer se... Q: What is the difference between research-grade and pharmaceutical-grade peptides? A: Research-grade peptides (RUO - Research Use Only) are synthesized for laboratory investigation and are not manufactured under pharmaceutical GMP conditions. Pharmaceutical-grade peptides undergo FDA-regulated manufacturing. All peptides on this site are designated for research purposes only. Q: Are research peptides approved for human use? A: No. All peptides featured on Prescribed Vials are designated Research Use Only (RUO). They are not approved by the FDA for human consumption, veterinary use, or any therapeutic purpose. All content describes preclinical laboratory studies, not clinical recommendations. Q: Where can I source research-grade peptides? A: Research-grade peptides with 98%+ purity, HPLC verification, and third-party COAs are available at researchvials.com. All peptides ship from the USA with cold-chain packaging to maintain product integrity.
