Very good would order agian
COA MW listed clearly.
NAD+ 500mg, thorough docs…
Switched to NAD+ 500mg here after loose vials elsewhere and this shipment had secure padding plus independent third-party testing on the COA.
Our group runs NAD+ 500mg pretty regularly and batch-to-batch consistency has been excellent across three separate reorders. Each lot reconstituted cleanly and the HPLC profiles looked aligned with prior material. That predictability saves us time when we are scaling up assay prep. I have already recommended Scientipeptides to two other labs on our floor.
NAD+ 500mg: consistent bench assays, quality glass vials.
international shipping was smooth, they stock less common research peptides we could not find elsewhere, and NAD+ has been consistent across our bench assays…
tamper-evident seals on the NAD+ 500mg vials were fully intact and the COA matched the lot on arrival!!
The NAD+ 500mg order came with independent third-party lab testing available on request and Scientipeptides carries enough of the less common research compounds our program needs that I keep coming back even when I am juggling a dozen other procurement tasks.
Very satisfied.
NAD+ w/ COA plus sterility/endotoxin figures
Site specs matched what hit the bench, fill weight and labeling were accurate with no surprises. We moved over from a vendor that kept listing one thing and shipping another, and this felt straightforward from checkout to unpacking.
We needed the COA for a specific lot of NAD+ 500mg and support helped us track it down w/ the right batch number the same afternoon. The pdf matched our vial label and saved a lot of back and forth with procurement. Material arrived cold and the packaging looked solid for lab storage. Really appreciate that kind of follow-through on documentation. This is exactly the supplier we want for ongoing enzyme work.
COA lot matched the vial label exactly, clean paperwork…
great nad+ 500mg!!
All good.
nad+ 500mg perfect.
NAD+ 500mg went into bacteriostatic water fast, HPLC trace was clean/no unexpected side peaks, and our multi-vial bulk pull shipped sorted by lot. Already pointed a couple colleagues at Scientipeptides.
We moved our NAD+ sourcing here after inconsistent paperwork elsewhere and the endotoxin and sterility figures on the COA were exactly the kind of detail our QA folder expects. Institutional PO ordering was straightforward with no back-and-forth on vendor setup. Material arrived cold, labels matched the documentation, and restocks have been reliable since the switch. Glad we made the change.
Tracking updates stayed accurate from dispatch through delivery, which made it easy to coordinate with our receiving team. Everything arrived when the portal said it would, and that kind of predictability is exactly what we want for lab restocks.
nad+ 500mg landed cold and the gel packs were still frozen inside the liner. A carrier mislabeled the outer carton once but support rerouted it same day and we had a clean lot on the bench!!
The NAD+ 500mg vials matched the stated fill on our balance every time we checked. That kind of accuracy gives me confidence before we prep working stocks for the bench.
support answered NAD+ questions fast.. helpful.
NAD+ 500mg, third-party COA, cold-packed, stiff cap.
We've been running NAD+ through our enzyme assays for a few months now and the performance has been steady lot to lot. Bench readouts stay in the expected range and reconstitution is straightforward every time. Scientipeptides has become a supplier we actually trust when timelines are tight. Pricing fits our grant budget better than most comparable sources we've quoted. Already planning the next reorder.
Full MW detail on the COA…
nad+ 500mg good.. reconstitution notes were pretty minimal but still satisfied.
NAD+ 500mg has been reliable for our lab work and Scientipeptides usually delivers what we need.. Restock timing on this one can run slow which is annoyng when we're mid-protocol but we'd order again.
Perfect glad we switched
Net peptide content versus gross mass was stated clearly on the product page. Saved us a conversion step before we even opened the vial.
Great NAD+ 500mg.. exactly right
We order NAD+ 500mg from Scientipeptides on a regular cycle and the overall reliability as a lab supplier has been strong. COAs show up with the shipment, lot numbers trace cleanly, and we have not had to chase missing paperwork. The last box did include a bit more packaging than the order really needed, which felt wasteful even though everything inside was protected. Still, for day-to-day sourcing this has become one of our dependable defaults.
NAD+ 500mg reconstitutes clean no cloudiness, third-party testing was available on request and endotoxin/sterility figures were on the COA.. solid repeat buy for our lab!!
The NAD+ 500mg specs listed on the site matched the vial and COA exactly, which made setup straightforward for our lab protocols. Reconstitution went clean with no particulate and the cold-chain packaging looked intact on arrival.. The invoice formatting was very basic but the line items were correct and I would happily order again.
Procurement needed a clean itemized invoice and this order had every line spelled out with no guesswork. Makes PO reconciliation straightforward when finance starts asking questions…
nad+ solid.. checkout clunky
Solid NAD+ 500mg.. very pleased
Good, checkout clunky.
discreet unbranded box sterility/endotoxin docs included all good
Shipment arrived still cold and the vials were frozen on the gel packs. We have been running it as a reference standard for method development and the chromatography profile has stayed consistent across lots.
their catalogue keeps less common research peptides in stock when other vendors show month-long backorders.
Excellant shipment!!
NAD+ 500mg order hit a minor shipping snag but support resolved it quickly, and they answered our documentation questions the same day!!
NAD+ 500mg dissolved clean in bac water, intl shipping smooth.
First NAD+ 500mg shipment got delayed in transit but support rec'd it sorted fast and sent tracking for the replacement. Replacement arrived w/ temp still good and qty was correct. We will keep ordering from them.
Received the order ahead of schedule with full documentation. The material integrated smoothly into our existing protocol.
We've reordered NAD+ 500mg several times and each batch has behaved the same in our prep workflow which keeps our assay setup predictable. The last shipment arrived complete with nothing missing from the packing list and every vial accounted for. Batch documentation was thorough and easy to file in our inventory binder so procurement had no questions. I've already pointed two colleagues in the lab toward Scientipeptides for their NAD+ needs.
NAD+ 500mg COA reported low residual TFA and our prep ran as expected. Cold pack intact, labels clear, moving on.
Perfect NAD+ 500mg.
We switched from our previous NAD+ supplier and I'm glad we did. Every vial showed intact tamper-evident seals when the box arrived. The powder looked uniform and the COA matched what we needed for bench prep. There was a bit more packaging than the order really needed, which felt like extra waste for a small restock. Still satisfied with the material and we would reorder from here.
NAD+ 500mg COA listed molecular weight and sequence clearly.. No guesswork matching our lab records and the vial label matched the paperwork.
We switched to Scientipeptides for NAD+ 500mg and the itemized invoicing made procurement painless. Clear line items w/ batch numbers and qty nothing got held up in accounts payable.
The NAD+ 500mg vial is proper borosilicate glass, not thin or cheap, and the crimp and stopper both feel lab-grade when you're pulling it from the cold box and getting it onto the bench. We've had zero breakage issues across two orders and the labeling was easy to read even under hood lighting which sounds small but it saves time every run!!
Great NAD+, rec'd fast.
International shipping to our lab was handled smoothly and tracking stayed accurate the whole way. Everything arrived cold with proper documentation. A bit more packaging than the order really needed but the vials were well protected and I'd reorder without hesitation.
Tracking on the NAD+ 500mg shipment stayed accurate through delivery and the cold-chain pack arrived still cold with clear storage and handling instructions on the insert.. the invoice formatting was very basic but everything else was dialed in and we'd reorder.
we keep coming back because the catalogue breadth covers what our research program needs without hunting multiple vendors.. Every shipment includes the certificate of analysis and it's easy to file with our batch records.
Love it..
Institutional PO went through w/o hassle, reorder shipped quick w/ accurate line items on the invoice…
We needed a dependable reference material while building out our NAD+ quant method, and this lot behaved predictably across calibration runs. Peak response stayed consistent run to run and the COA matched what we saw on the bench. Having something that stable makes validation work much less stressful. We have reordered twice since and both lots lined up cleanly. For method development that is the bar.
nad+ 500mg landed with gel packs still cold and the insulated wrap actually held temp all the way to our loading dock.
NAD+ 500mg dissolved clean.
Submitting an institutional PO for NAD+ 500mg was easier than our old workflow and accounts replied same day. Invoices came itemized w/ SKU, lot, and qty so procurement stopped chasing clarifications. The COA matched the vial label and everything landed cold-packed. Honestly this is the smoothest peptide ordering we have had in a while.
NAD+ 500mg PO went through clean w/ clear itemized invoicing for procurement. Emailed a documentation question and got a solid answer back fast so we will keep ordering…
Exactly as described.

Consistent lot to lot, no drift.
NAD+ 500mg showed up with desiccant included and intact inside the box. Delivery took a little longer than the estimate, but the material looked fine on receipt and we would order again.
Great NAD+, thanks!
Exactly as described.
Certificate of analysis came in the shipment for our NAD+ 500mg and the lot info was easy to cross-reference. We ran in-house HPLC on the first vial and the purity lined up with what the COA reported. Reconstitution was straightforward in the lab and the powder looked uniform going in. Packaging was clean and the vial label held up through handling. Will keep this on our standing order list for the next assay run…
NAD+ 500mg showed up on time and when I emailed a documentation question about the batch they answered the same afternoon.. solid supplier.
We ran NAD+ 500mg through our routine LC-MS check and the chromatogram was clean with no unexpected side peaks. Identity confirmation lined up with the expected mass and documentation. Reconstitution gave a clear solution with nothing odd in the fraction. That kind of data makes it easy to trust the material for downstream bench work. Already pointed a summer student toward Scientipeptides for their project stock.
Excellent NAD+ 500mg.
the batch documentation on NAD+ 500mg was thourough and easy to slide into our QA folder. COA lot number matched the vial and the HPLC summary was simple to parse. Cold-chain packaging showed up intact with tight seals. This stays on our approved vendor list.

Packaging was neat and the order showed up complete so we could get back to bench work without chasing missing paperwork.
Solid NAD+ 500mg.
The NAD+ 500mg arrived in discreet, unbranded outer packaging that suited our receiving process. Checkout on the site was a little clunky but the vial, labeling, and COA were exactly what we needed for bench work.
nad+ 500mg works great as a reference standard and the outer box was plain/unbranded!!
This was another NAD+ reorder for our enzyme panel and the documentation side has stayed reliable. The COA listed molecular weight and identity clearly and lined up with what we track internally. Insulated packaging with gel packs kept the shipment cool through a warm transit week. Vial labels were legible and held up after handling in the cold room. Tracking updates were sparse while it was en route though it still landed on time and intact. Overall we're satisfied and keeping this on our vendor list.
Ordered multiple NAD+ 500mg vials and they all arrived w/ COA in the box. Solid value for our lab budget and bulk handling was clean no mixups.
For a lab watching every line item this NAD+ 500mg pricing has been a real win on value without cutting corners on paperwork. We have put three orders through now and each batch came with a proper COA and clean labeling for our inventory system. One vial cap was a little stiff to break but nothing a standard crimper could not handle. Overall I am genuinely pleased with what we are getting for the budget and I would reorder without hesitation.
NAD+ 500mg arrived in a heavy glass vial with a clean crimp and Scientipeptides answered our documentation questions the same afternoon we emailed.

We've been reordering from Scientipeptides for a while now and the specs keep getting easier to read. The net content versus gross mass was stated clearly on the label so inventory logging took minutes instead of a back-and-forth with the team. Cold-chain packaging looked good on arrival and the COA matched what we filed from the last lot. Bench prep has been routine and nobody on the floor is second-guessing the numbers anymore and I honestly do not bother price-shopping because the time saved on documentation alone is worth it.
LC-MS identity matched the expected nominal mass for NAD+ and the itemized invoice made procurement reconciliation painless.
Weighed the vial on receipt and got the full stated quantity with minimal loss to the cap liner.
The NAD+ 500mg showed up with gel packs still cold and the vials were sealed tight so we unpacked and logged everything same day without any worry about temperature drift.. everything looked exactly like prior orders and we will definitely reorder.

The NAD+ 500mg arrived in a thick glass vial that felt properly made and the rubber stopper seated cleanly without any chips or cracks around the neck which matters when you're handling it in the hood all day. Documentation was solid and bench prep went smoothly. Yes there was a bit more packaging than the order really needed but I'd rather have extra padding than a cracked vial and overall I'm very happy with this lot!!
NAD+ 500mg, perfect.
Rec'd material w/ a COA that lists molecular weight and sequence details our team expects on file. Temp on arrival was fine and labeled qty matched what we ordered. We also grabbed a couple less common research peptides here that other catalogs did not stock. Straightforward lab supply, no surprises.
The order arrived complete with every vial accounted for and the COA tucked in the box so nothing was missing from what we requested.
Fill looked right on the bench and we saw minimal handling loss compared with prior vendors. Documentation was complete and the lot traced cleanly to the label. The invoice formatting was very basic for our accounting export, but the numbers were accurate and we would order again.

Documentation was straightforward and the material looked clean on receipt. For a cofactor we rely on regularly, that kind of consistency keeps our lab running without surprises.
NAD+ 500mg showed up with every tamper-evident seal intact, though delivery ran a bit past the estimate and support took about a day to reply, but I'd reorder.
i have already pointed two colleagues here after our last NAD+ restock. The COA listed molecular weight and identity clearly and the measured fill per vial lined up with the stated 500mg spec. Invoicing was straightforward for our purchasing team and the vials arrived with intact seals. We like having that level of traceability before anything hits the bench…
All good thnaks…
Moved our NAD+ sourcing here and procurement finally gets clear, itemized invoicing on every PO. Delivery took a little longer than the estimate, but the shipment arrived intact with matching labels, so we are sticking with them.
Excellent purity for the price point. Have recommended NAD+ 500mg to two collaborating laboratories for their assay development.
