Usually ships as a in a sealed vial—10mg per vial, which is a pretty standard research dose for those running longer protocols, and we pack it with a desiccant pouch to keep moisture out during transit.
Purity is tested at 99% or better via HPLC, and we do send a COA with each order; it's not something we just claim without backing up, so you can verify batch yourself before use it.

You'll need to store it at 2-8°C and keep it away form light, or it'll degrade faster than teh 24-month shelf life suggests—most buyers use a small lab fridge for this, but a regular fridge works if it's stable.
We usually have stock on hand for the 10mg vials, but confirm lead time if you need more than 50 units or so; smaller orders ship within a week, bigger ones might take a bit longer depending on the batch schedule.

It's not for human use—research grade only, and we don't recommend it for anything beyond in vitro work, so if you're planning animal studies, check your own protocols first because our company can't advise on that.
Also, the vial itself is a standerd 2ml crimp-top, so it'll fit most reconstitution setups you already have, and we include a foil pouch for extra light protection during storage.
