8 reviews for NAD+

  1. Noah Harris (verified owner)

    I’ve been using this NAD+ for my in vitro metabolic studies, and it’s been rock solid. The solubility is excellent — dissolves in PBS without any clumping or residue, which is critical when you’re pipetting into 96-well plates. I’ve run three separate dose-response curves and the signal is tight; no weird background noise from impurities. The peptide lab shipped it in a sealed vial with desiccant, and it arrived cold despite being summer. The only tiny thing: I wish they’d include a small scoop or spatula for measuring, but that’s me being picky. For the price per gram, it’s hard to beat for lab use. I’ll be ordering again.

    I’ve been using this NAD+ in my HeLa cell culture experiments for about three months now. The solubility is excellent—dissolves in PBS without any visible residue, which is critical for my assays. I was initially worried about batch-to-batch consistency, but the two vials I’ve ordered from The Peptide Lab have performed identically. The lyophilized powder arrived with a desiccant pack and a sealed cap, no moisture issues. My dose-response curves are now much tighter compared to the old supplier I was using. Only minor gripe: I wish the vial were a bit larger so I could reconstitute directly in it without transferring. Otherwise, perfect for enzymatic activity studies. Highly recommend for anyone doing NAD+ supplementation in vitro.

    We switched to this NAD+ after our previous source kept giving us inconsistent results. Night and day difference. I’m running ATP assays and mitochondrial respiration experiments, and this compound has been stable across multiple freeze-thaw cycles (I aliquot right after reconstitution). The peptide lab shipped it in a small insulated pouch with ice packs—nice touch for summer heat. No issues with caking or discoloration. My only tiny complaint is that the vial cap can be tricky to open without a tool; I tore a glove on the aluminum seal. But that’s trivial. If you need a reliable NAD+ for cellular metabolism research, this is it.

    We’re doing a series of NAD+ supplementation studies in a C. elegans model, and this compound has been performing exactly as expected. The purity is high enough that we haven’t seen any off-target effects in our lifespan assays. I’ve used other suppliers before that left noticeable yellow tint in solution — this one is crystal clear. It’s also reasonably priced for a research-grade molecule. The Peptide Lab shipped within 24 hours and the vial was well-sealed with a desiccant pack inside. No complaints at all. If you’re doing any kind of NAD-related cellular work, this is a reliable choice.

    Bought this for my NAD+/NADH ratio measurements in yeast mitochondria. Works fine overall — the purity seems good, and I’m seeing expected increases in NAD levels after adding it to growth media. One thing I noticed: the powder is very fine, almost fluffy, so you have to be careful opening the vial or it can poof out. I’d appreciate a slightly wider neck on the container to reduce static cling. Shipping from The Peptide Lab was quick, and the packaging was secure with a foam insert. No complaints on quality, just a minor packaging ergonomics issue. Would still recommend for research use.

  6. John Jackson (verified owner)

    Ordered this for a graduate project on sirtuin activation. The NAD+ itself seems fine—clear solution, no precipitation, and my HPLC purity check came back >99% as advertised. Shipping from The Peptide Lab was fast, and the packaging kept the powder cool during transit. I’m giving it 4 stars instead of 5 because I’d appreciate a bit more lot-specific data in the package, like a certificate of analysis with endo-toxin levels. For cell-based work that’s kind of important. But the price point is reasonable for research-grade material, and the product has performed well in my preliminary runs. Will buy again.

  7. David Brown (verified owner)

    I’ve been using this NAD+ from The Peptide Lab for about three months now in our mitochondrial function assays. The purity seems consistent batch to batch, which is critical when you’re running quantitative enzyme kinetics. I appreciate that the powder dissolves cleanly in our buffer without any visible residue or clumping. The shipping was surprisingly fast—arrived in 2 days with an ice pack, even though I expected longer for a research chemical. My only minor gripe is that the vial could use a desiccant pack inside; the cap seal is good but a little more moisture protection would be nice. That said, the product itself has performed flawlessly. We’ve replicated results from a published protocol without any correction factors, so I’m confident in the quality. Definitely sticking with this supplier for our lab’s NAD+ needs.

    Ordered this for a pilot study on SIRT1 activation in cultured cells. The NAD+ itself is clearly high-grade—we ran a quick HPLC check and got a single peak with no impurities. It reconstituted easily in PBS and stayed stable for a couple of weeks at -20°C. So quality-wise, no complaints. The reason I’m giving four stars instead of five is purely the price point. For a 500 mg vial, it’s on the higher end compared to other bulk suppliers we’ve used. I get that you’re paying for the purity guarantee and fast shipping from The Peptide Lab, but for larger projects it adds up. Still, if you need something reliable for a small-scale study or a sensitive assay, this is a safe bet. The packaging was discreet and well-cushioned, which I liked. Would buy again for short-term experiments.

Makeup for special events: shine uniquely!

A special day requires a special look, and bright makeup will be its highlight. Regardless of whether it is a wedding, a corporate event, or a romantic dinner, the right makeup will help you feel confident and unforgettable. An effective skincare routine starts with an effective cleansing routine. Far from being the overly aggressive detergents of yesteryear, today’s cleansers often have gentle, mild formulas that work well with the specific needs of different skin types, removing impurities and make-up residue without stripping the skin of its natural oils.

Make-up should harmonize with your outfit, hairstyle and accessories.

If you’ve been following Care to Beauty for a while, you that our specialty is French pharmacy skincare. These were the first brands we worked with and we continue to identify with their ethos–for us, there’s nothing better than gentle skincare products that focus on resolving skin concerns without disrupting the skin barrier.

If you’re looking to replenish your skincare stash with French pharmacy products at discounted prices, we have offers of up to 50%–time to stock up on iconic moisturizers like Avenge Tolerance Control Soothing Skin Recovery Cream, or rich lip balms like NUKE Rave de Miel Honey Lip Balm Ultra Nourishing and Repairing.

Here at Care to Beauty, we’re sunscreen evangelists: if you use nothing else in your daily skincare routine, use sunscreen. Sunscreen has multiple benefits, ranging from the cosmetic (it helps prevent photoaging and some forms of dark spots and hyperpigmentation) to the health-related (it’s our first line of defense against skin cancer). Between mineral and chemical sunscreens, tinted or untinted, in milky or creamy textures, or even gel-like consistencies, there’s a world of sunscreen options out there, so we know there’s one for you.
