We're sitting on a 2-year shelf life for the lyophilized powder, which basically means you can stock up without worrying about it degrading fast—most buyers go with the 10mg vials for the balance of convenience and cost.

Purity hits 99% or better, and we run HPLC on each one (usually 2-4 weeks for full COA turnaround), so you're not guessing at what's in the vial. The white powder reconstitutes cleanly in sterile water or bacteriostatic, but it's not suited for anything beyond research use—no human consumption, period. One thing nobody asks but should: teh powder can clump if you leave the cap off too long in humid air, so reseal quickly after reconstitution.

Customiztion is pretty straightforward—we can do 2mg, 5mg, 10mg, 15mg, or 20mg per vial, and the MOQ is just 1 box of 10 vials. Lead time on custom specs is about 20 days or so, give or take depending on the batch size. The 5mg option is tighter tolerance than the standard 10mg in terms fill accuracy, but most researchers don't need that level of precision anyway.

Storage is cool and dry—nothing fancy, a desk drawer works fine as long as it's not above 25°C. And the packaging is 10mg per vial in a box of 10, but our company can also do individual vials if you're just testing a small batch.

Actually, we've had a few buyers try to use it for cell culture work, and purity holds up better than reagent grade for that—just keep it away form any application involving living organisms beyond in vitro. That's pretty much it.
