We're running this at >99% purity consistently batch to batch, and it come as that you'd expect for research use — typically in 10 vial boxes, though we can adjust packaging if needed.
You'll want to keep the unopened vials in a cool, dry place, but after reconstitution it's got to sit at 2-8°C, and we've found most buyers lose track of that and end up degrading activity pretty fast.

Basically, it's not for anything other than research, and the molecular weight sits at about 4108.6 g/mol, which matters for dosing calculations if you're running in vivo or in vitro work — teh 24-month shelf life holds up fine if stored properly.

One thing we don't push this for is any sort of clinical or human use, and that's a hard line; some groups try to push peptides into applicaions they aren't designed for, so we're blunt about it.

We've got COA and HPLC data on every lot, and the facility runs under ISO9001 — it's not the flashiest statement, but it means the process is consistent, and we usually have stock ready within 20 days or so depending on order size.
Custom formulations are actually availble as well, with private labeling or packging tweaks if you need something specific for a study setup, though lead time might stretch a bit for that.
