It's worth being upfront about—this isn't something you'd use in clinical or human appliction, it's strictly for lab research, but for that purpose it actually performs really well with ≥98% purity by HPLC and stability when stored at -20°C dry and away form light.
We typically run it through multiple QC checks during synthesis, and you'll get a COA and MSDS with every batch, though lead times can vary a bit so just confirm when you're ready to order.

Most buyers in the peptide R&D space go with teh 10mg or 50mg vials because they're easier to handle for small-scale assays, and our company can do bulk up to gram quantities if you need it.
It's soluble in DMSO and only slightly in water, so for most buffer systems you'll want to pre-dissolve in DMSO first—something a lot of researchers don't think to ask until they're staring at a cloudy solution.
Also, the molecular weight is calculated but not finalized on CAS yet, so we usually have stock but double-check lead time if you're on a tight deadline; about 20 days or so for standerd orders.
