Research Peptide FAQ

01

Are all 99PurityPeptides products tested for purity and quality?

Every research peptide undergoes rigorous third-party analytical testing before release. Our quality control process includes High-Performance Liquid Chromatography (HPLC) to verify purity percentages, Mass Spectrometry (MS) to confirm molecular weight and sequence accuracy, and peptide content analysis to ensure accurate concentration. Each product batch receives an individual Certificate of Analysis (COA) documenting test results, storage recommendations, and lot-specific data. This analytical verification ensures you receive research-grade materials meeting published specifications for your laboratory investigations.
02

What purity levels are standard for research peptides?

99PurityPeptides specializes in high-purity research compounds with most products achieving 95-99%+ purity as determined by HPLC analysis. Standard catalog peptides typically meet ≥95% purity suitable for most research applications. Premium-grade options offer ≥98% purity for experiments requiring exceptional quality, and custom synthesis can target >99% purity for highly sensitive analytical work. Product pages clearly indicate tested purity levels, and COAs provide exact percentage for your specific lot. Higher purity reduces experimental variables caused by impurities or synthesis by-products.
03

How do I interpret the Certificate of Analysis (COA)?

Certificates of Analysis include several key data points for research validation. The HPLC chromatogram shows the purity peak representing your target peptide versus any impurities; the percentage represents the area under the curve for your compound. Mass Spectrometry data confirms the molecular weight matches the theoretical weight calculated from the amino acid sequence. Peptide content indicates the actual peptide mass as a percentage of total powder weight (remainder being counterions and moisture). Storage conditions specify temperature requirements for maintaining stability. For assistance interpreting COA data, contact our technical team.
04

What does "Research Use Only" mean for these products?

"Research Use Only" (RUO) designation means these peptides are manufactured and sold exclusively for laboratory investigation by qualified researchers in controlled settings. These products are not intended for, and must not be used for: human consumption or administration, medical treatment or diagnosis, veterinary applications, food or cosmetic production, or any purpose outside legitimate scientific research. Researchers must handle RUO materials according to institutional biosafety protocols, maintain appropriate documentation, and ensure compliance with their organization's research guidelines. This designation protects both researchers and suppliers under current regulatory frameworks.
05

Can peptides be damaged during shipping or storage?

Research peptides are relatively stable when properly packaged and stored, but can degrade under adverse conditions. Our shipping protocols use temperature-controlled packaging with cold packs or dry ice to maintain product integrity during transit. Upon receipt, immediately transfer peptides to appropriate storage (-20°C for lyophilized products). Exposure to heat, humidity, or repeated temperature fluctuations accelerates degradation. If you suspect shipping damage (compromised packaging, warm products, visible moisture), do not use the material—contact us immediately for replacement. Proper storage and handling maintains peptide quality throughout its usable lifetime.
06

Can I use these peptides for any purpose outside research?

No. 99PurityPeptides products are manufactured, labeled, and sold exclusively for in vitro laboratory research applications. Using these compounds for human consumption, athletic performance, bodybuilding, medical treatment, or any non-research purpose violates regulatory guidelines, our terms of sale, and potentially federal and state laws. We monitor purchases for compliance and reserve the right to refuse orders that appear intended for inappropriate use. Researchers must certify that products will be used only for legitimate scientific investigation in controlled laboratory environments under appropriate oversight.
