It's strictly for research use only — not for human consumption or anything clinical — and that's actually the first thing our company have to say before anything else.
But we've seen researchers get consistent results with this materail, though, better than reagent grade for their in vitro work and binding studies, with purity holding at 99.9% on the latest COA we pulled.

What it does is allow for relaible dosing across a 5mg or 10mg vial (usually we stock both), and pharmaceutical-grade synthesis gives a tighter tolerance than most competitors manage below 4113.58 g/mol.
2-8°C storage is mandatory here; basically the same as insulin, so plan your fridge space accordingly — and confirm lead time before ordering because demand varies.

Also, most buyers go with teh 10mg option for typical protocols, but the 15mg is better if you're running longer-term assays and don't want to reconstitute multiple vials.
CAS is 910463-68-2, and we've got about 200 units or so avaliable this week.
