NAD⁺

NAD⁺ (Nicotinamide Adenine Dinucleotide) is a critical coenzyme found in every living cell. It plays essential roles in cellular energy metabolism, DNA repair, and sirtuin activation. Research into NAD⁺ supplementation and its precursors is one of the most active areas in aging and longevity science.

When stored at -20°C as specified, NAD⁺ maintains 95%+ stability for 24+ months. Keep sealed and protected from light and moisture. Once opened, use within 6 months for optimal activity. NAD⁺ is hygroscopic, so minimize exposure to ambient humidity.

NAD⁺ is supplied as a high-purity powder (≥99%). For solution preparation, dissolve in sterile water or appropriate buffer at your desired concentration. NAD⁺ solutions are most stable at neutral pH (6.5–7.5). Prepare fresh solutions for each experiment when possible, as dissolved NAD⁺ degrades faster than the dry powder.

Every batch is independently tested by accredited third-party laboratories with full Certificates of Analysis (COA) available on request. We guarantee ≥98% purity across our catalog, use pharmaceutical-grade lyophilization, and ship with cold-chain packaging to preserve compound integrity. Our research-grade peptides are manufactured under strict GMP-compliant conditions, ensuring consistency and reliability that many competitors cannot match.

Yes. We can provide HPLC, mass spectrometry, endotoxin testing, and amino acid analysis reports for any product. If you need a specific assay or custom testing protocol for your research, contact us at [email protected] and we will coordinate with our laboratory partners to accommodate your requirements.

Absolutely. We offer tiered pricing for research institutions, universities, and laboratories ordering in volume. Discounts typically start at 10+ units and scale with quantity. Contact us at [email protected] with your institutional details and estimated quantities for a custom quote. We also support purchase orders (PO) for qualifying institutions.

All orders ship free with same-day processing (orders placed by 12 PM PST). Packages are sent via USPS Priority or UPS Ground with temperature-controlled packaging. Lyophilized peptides are shipped with cold packs to maintain stability. Domestic orders typically arrive within 2–3 business days. Tracking information is provided via email as soon as your order ships.

Due to the nature of research chemicals, we cannot accept returns on opened products. However, if your order arrives damaged, contaminated, or does not meet the stated purity specifications, we will replace it or issue a full refund. Please contact support within 48 hours of delivery with photos of any issues.
