We've been moving this one for a while now, and purity consistently comes back above 99% form HPLC—that's tighter than most labs require, so you're not chasing ghost peaks in your assays.

What that means in practice is you can dose at 10mg or 15mg and expect the same baseline every time, which is critical when you're running or comparing batches side by side over 20 days or so.

The freeze-dried cake is stable at room temp for a couple of years (usually 2-4 weeks if you leave it out, but we recommend cool and dry storage anyway), and we ship it in boxes of 10 vials—your MOQ is just one box, so you're not stuck with 50 units you don't need yet.
Most buyers go with teh 10mg for smaller-scale work, but if you're running high-throughput studies, the 30mg or 60mg vials save you reconstitution time—though we don't recommend it for anything beyond research use, it's not formulated for clinical or human applicaion.

One thing people don't always ask: the powder can clump if exposed to humidity during reconstitution, so we include desiccant packs in every shipment, and that's something you'll appreciate if you've ever had a vial seize up on you mid-experiment.
