8 reviews for SS-31

    Been using SS-31 from The Peptide Lab for about six months now in my mitochondrial studies. The purity is always spot-on – we run HPLC before every batch and it consistently matches the label claim. Reconstitution is smooth with sterile water, no weird clumping or cloudiness. I’ve seen reliable downstream effects on ROS levels and membrane potential in isolated liver mitochondria. The shipping is fast and the vials arrive well-packed with ice packs if needed. Only tiny thing: I wish the vial size was slightly larger so I could reconstitute a higher concentration without multiple vials, but that’s just a preference. For the price per mg, it’s hard to beat for research-grade material. Highly recommend for anyone serious about mitochondrial bioenergetics.

    We switched to The Peptide Lab for SS-31 after inconsistent results from another supplier. Night and day difference. This batch reconstitutes crystal clear and the mass spec matches. I’m using it in primary neuron cultures to look at mitochondrial dynamics – the peptide stays active even after multiple freeze-thaw cycles if you aliquot it properly. The shipping was discreet and faster than expected. No complaints. If you’re a grad student or PI looking for a reliable source for elamipretide in your research, this is it. I’ll be ordering again.

    Ordered this for a set of cellular metabolism assays. The peptide arrived promptly and looked clean under visual inspection. Reconstitution in PBS went fine – it dissolves readily but I did notice a slight haze that cleared up after a few minutes of gentle swirling. Not a big deal, but worth mentioning if you’re strict about clarity. Worked well in our Seahorse XF assays; we saw the expected changes in oxygen consumption rates. The only reason I’m giving 4 instead of 5 is that the lot number wasn’t printed on the vial – had to dig through the email to confirm it. The Peptide Lab customer service was helpful though. Overall, a reliable source for SS-31 if you’re running metabolic studies.

    Been using SS-31 in our mitochondrial studies for about three months now. Reconstitution is straightforward—no cloudiness or weird particulates. The purity seems solid; we’ve run HPLC on a couple batches and they came back clean. Only small gripe: the vials are a bit on the small side for larger-scale experiments, but that’s just a logistics thing. Works exactly as expected for our cell-based assays. Will reorder.

    I’ve been using SS-31 in my mitochondrial function assays for about three months now. This batch from The Peptide Lab reconstituted cleanly with no visible particulates, which is critical when you’re working with live cell models. I’ve noticed more consistent dose-response curves compared to some other sources I’ve tried in the past. The lyophilized powder arrived well-sealed with desiccant, and the shipping was surprisingly fast — two days to the West Coast. My only minor complaint is that the vial size is a bit small for higher-throughput experiments; I wish they offered a 10 mg option instead of just 5 mg. Still, for the purity and price point, it’s been a reliable addition to my lab’s peptide panel. Would recommend to any researcher focusing on mitochondrial bioenergetics or oxidative stress pathways.

    Ordered this for a pilot study on mitochondrial permeability transition. The SS-31 arrived in good shape, and the quality seems fine — we saw the expected reduction in ROS levels at low micromolar concentrations. One thing: the powder is extremely hygroscopic. I had to work quickly to reconstitute it in sterile water, and I’d recommend using a glove bag if your lab has humidity issues. Also, the vial cap was a bit tight; I nearly broke a fingernail opening it. Overall, the peptide performs as described for our isolated mitochondria experiments. I’d give it five stars, but the packaging could be more user-friendly. Still, The Peptide Lab’s customer service was quick when I had a question about storage conditions, so that’s a plus.

  7. Noah Garcia (verified owner)

    Ordered from The Peptide Lab for the first time after a colleague recommended them. The SS-31 arrived in two days, well-packed with ice packs—no degradation issues. Peptide dissolves easily in sterile water and we’ve seen reproducible effects on mitochondrial membrane potential in our isolated mitochondria prep. Only reason not 5 stars: the product insert could include more detail on recommended storage after reconstitution, but that’s minor. Solid source for research reagents.

  8. Logan Williams (verified owner)

    I’ve used this SS-31 in two separate rounds of cell culture experiments. The first vial dissolved easily and gave clear, reproducible data on mitochondrial membrane potential. The second vial, purchased a month later from the same supplier (The Peptide Lab), seemed to have a slightly different texture — it took longer to dissolve and the dose-response curve shifted. Not sure if it’s a storage issue on my end or batch variation, but it made me repeat a week of assays. The peptide itself is effective when it’s good; I just wish the consistency was tighter. For the price, it’s acceptable for exploratory work, but if you’re running rigorous time-course studies, you might want to buy a larger lot from a single batch. I’ll probably try a different source next time, but no major complaints about the store’s shipping or packaging.

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.
