Stock's looking good right now — we can ship within 5-7 business days typically, and teh cold chain is set up for internatioanl with gel packs, though confirm if you need dry ice for longer transits.

Most buyers go with 500mg vials since it's easier to reconstitute than bulk powder, but our company can customize packaing if your lab prefers drums or smaller aliquots (usually 2-4 weeks lead time for that).

The purity runs above 98% by HPLC, which is tighter than reagent grade for this, and we've found it holds up better than some competitors when stored at 2-8°C away form light — it's actually pretty stable for about 24 months if you don't freeze-thaw repeatedly.
It's not suited for oral formulations or anything beyond lab work, so keep it in research only, and honestly, we usually see it used in mitochondrial studies or cellular metabolism assays rather than direct anti-aging trials.

One thing you might not think to ask — freeze-dried cake can be slightly hygroscopic, so let it warm to room temp before opening the vial, or you'll get clumping that's a pain to dissolve evenly.
