| Molecular weight | ~663.4 Da (oxidized form; minor variation may occur depending on counterion or formulation). |
| Form | Supplied as lyophilized powder in glass vials. |
| Purity | Typically ≥99%, verified with COAs |
| Solubility | Lyophilized powder is generally soluble in sterile water or appropriate buffers |
Batch: EP-250501-ND500
Handling & Storage Guidelines
NAD⁺ is highly hygroscopic and sensitive to moisture. It is critical to store vials in a cool, dry environment to maintain stability. Unopened vials are typically stored at 2–8 °C (36–46 °F) and protected from light and moisture. For longer-term storage, freezing at –20 °C (–4 °F) is preferred unless otherwise specified.
If reconstitution is required, dissolve the lyophilized material using bacteriostatic water or an appropriate laboratory buffer in accordance with institutional protocols. You can order bacteriostatic water along with your NAD⁺ for convenience and assured quality.
Prepare solutions under controlled conditions to minimize contamination. Aliquot reconstituted solutions into smaller volumes to avoid repeated freeze–thaw cycles, which may compromise compound integrity.
Short-term working solutions are generally stored at 2–8 °C (36–46 °F) and used promptly, while long-term solutions are typically stored frozen. Standard laboratory safety practices and institutional biosafety guidelines should be followed at all times.
COA / Quality Assurance
Eternal Peptides provides Certificates of Analysis (COAs) for every NAD⁺ product lot, ensuring transparency and batch-level verification. COAs typically document compound identity confirmed by HPLC and/or mass spectrometry, purity analysis, and storage recommendations specific to each lot.
Where applicable, additional testing such as sterility and endotoxin assessment is also included.
All analytical testing is conducted through independent third-party laboratories, such as Janoshik, to support reliable and reproducible research use. Each COA is lot-specific and fully traceable, with unique batch identifiers that align with product labeling. Find COAs on our Lab Tests page, or ask for more information from our support team.
Legal / Regulatory Disclaimer
Eternal Peptides supplies NAD⁺ strictly for laboratory research use only. It is not approved for human or veterinary use, clinical administration, therapeutic applications, or diagnostic procedures. The safety and efficacy of NAD⁺ in humans have not been established.
As the purchaser, you are responsible for ensuring compliance with all applicable local, state, and federal laws, as well as institutional biosafety policies and research-use regulations.
Any misrepresentation of intended use or failure to adhere to regulatory requirements may result in legal or regulatory consequences.
Always quality-tested, verified with third-party COAs
At every step, we prioritize quality by conducting rigorous third-party testing on all our products. These tests focus on five key characteristics — identity, purity, sterility, endotoxin levels, and heavy metal content — ensuring that each product meets the highest standards of quality, with independent third-party Certificates of Analysis (COAs) to verify our commitment to excellence.
Identity Test
Identity testing ensures that the product contains the correct ingredient as labeled, verifying its authenticity and matching it to established reference standards.
Purity Test
Purity and concentration testing verifies that the ingredient is present in the correct amount, with a purity of 99% or higher to meet stringent quality standards.
Sterility Test
Sterility testing ensures that the product is completely free from bacteria, fungi, and other microorganisms.
Endotoxin Test
Endotoxicity testing specifically detects and quantifies lipopolysaccharides (LPS), components of bacterial cell walls, to ensure the product is free from endotoxins.
Heavy Metals Test
Heavy metals testing ensures that the product is free of heavy metals such as lead, arsenic, mercury, cadmium, and other heavy metals.
