Every lot is tested by an independent ISO 17025-accredited laboratory before release. The certificate of analysis reports HPLC purity, mass-spectrometry identity confirmation, and appearance — and it is issued against the specific lot you receive, not a representative batch. You can look up any lot's COA from the code printed on the vial label.
Orders are processed Monday to Friday, excluding U.S. federal holidays, within 1–2 business days. Orders placed before 5:00 pm Eastern on a business day ship the same business day. We ship FedEx 2-day standard with tracking, within the United States only. Shipping is free on every order to the continental US.
Store lyophilized vials sealed at -20 °C, protected from light and moisture. Solutions such as bacteriostatic water are stored at controlled room temperature. The exact storage conditions for this item are listed in the specifications on this page and printed on its certificate of analysis.
Compounds ship as lyophilized (freeze-dried) powder, which is stable at ambient temperature for the duration of transit, so orders travel in standard parcel packaging without cold-chain shipping. Short periods at room temperature in transit are normal and expected. Purity is verified at lot release.
For volume pricing, email hello@peptriva.com with the items and quantities you need and we'll come back with pricing and lead time.
Each lot carries a best-by date on the vial label and on its certificate of analysis. Stored as specified, lyophilized material is typically stable for 24 months. Actual stability depends on the sequence and on storage conditions after delivery.

Yes. Every NAD+ vial ships with an independent laboratory certificate for the exact lot inside it, not a representative batch. Lot NJ500-260503 reports 99.61% purity by HPLC-UV and 527.61 mg measured net content, alongside LC-MS identity confirmation and endotoxin testing by LAL in accordance with USP <85>.

Certificates are stored and searchable by batch number at /coa, the QR code on the vial opens the results for that lot, and the same link is sent with your order confirmation. NAD+ is sold for research use only, not for human or veterinary use.

Independently verified. Purity is measured by an independent US laboratory, currently Freedom Diagnostics of Franklin, Tennessee, and not in-house. Lot NJ500-260503 reports 99.61% by HPLC-UV as an area percentage. Peptriva holds ISO/IEC 17025 and ISO 9001.

Heavy metals are tested and reported within the purity panel. Recent lots across the catalog have reported between 99.58% and 99.91%. Because the figure comes from a laboratory that does not sell the product, it can be checked against the certificate rather than taken on trust. NAD+ is sold for research use only, not for human or veterinary use.

Every lot, and twice. Each lot is tested once when it is finished at the manufacturing facility and again when it arrives at our cold-chain center, both times by third-party labs. No lot stands in for another, and the certificate is matched to the lot number printed on your vial.

The second test is enforced in our code: a lot cannot move into sellable stock until both certificates are on file. That is why a certificate exists for every vial sold rather than for one showcase batch. Certificates are stored and searchable by batch number at /coa, the QR code on the vial opens the results for that lot, and the same link is sent with your order confirmation. NAD+ is sold for research use only, not for human or veterinary use.

Four, on every lot. LC-MS confirms identity, HPLC-UV measures purity as an area percentage, net content is weighed and reported in milligrams, and endotoxin is tested by LAL in accordance with USP <85>. Heavy metals are tested and reported within the purity panel.

The full panel is included with every order rather than supplied on request. The endotoxin test is run in duplicate, with both replicates reporting Pass, and net content is weighed rather than assumed, frequently returning above the labeled amount. NAD+ is sold for research use only, not for human or veterinary use.

FedEx 2-Day from US distribution, tracked, with cold-chain handling. Shipping is free on every order to the continental US, and the tracking number is sent with your order confirmation, so the package is traceable from our cold-chain center to your door.

Speed does not come at the cost of documentation. Because a lot cannot enter sellable stock until both third-party certificates are on file, what ships quickly also ships documented. NAD+ is sold for research use only, not for human or veterinary use.

Three ways, all resolving to your specific lot. Search the batch number at /coa, scan the QR code on the vial, or open the link in your order confirmation. Your vial is from lot NJ500-260503, which reports 99.61% purity and 527.61 mg net content.

Vials are lot-coded and certificate records are stored rather than issued on request, so a lot bought months ago can still be looked up. Full testing detail is on the FAQ. NAD+ is sold for research use only, not for human or veterinary use.

Yes. The certificate is matched to the lot number on the vial, not to a representative sample. The lot currently on file is NJ500-260503, tested by Freedom Diagnostics (Franklin, Tennessee) under accession 2606300392. A lot cannot be moved into sellable stock until both its certificates are on file, which is enforced in code rather than by policy. Every lot on file is listed in the COA library.
99.61% by HPLC-UV on lot NJ500-260503, with identity confirmed by LC-MS. That figure is the independent laboratory's result for this specific lot, and it is printed on the certificate linked from this page. What HPLC purity and LC-MS identity each prove is covered in the FAQ.
Independently tested. Every lot is tested twice by third-party laboratories: once when the lot is finished at the manufacturing facility, and again when it reaches our cold-chain distribution centre. The arrival re-test is run by Freedom Diagnostics in Franklin, Tennessee, and that is the certificate published here.
Yes. Endotoxin is measured by the Limulus amebocyte lysate assay in accordance with USP <85>, run in duplicate. Both replicates passed on lot NJ500-260503. The result appears on the independent certificate as its own line. Why endotoxin matters in a research setting is covered in the FAQ.
Net content is measured per lot and printed on the certificate. Lot NJ500-260503 reported 527.61 mg. Net content is measured rather than assumed, which is why it is reported as a figure instead of a tick. Every lot's measured content is in the COA library.
Yes. Certificates are stored against the lot, so a past order's certificate stays retrievable by its lot number. The lot is on the vial and on the order confirmation, and the QR code on the vial opens that lot's current results.
