It's pretty much always in stock at smaller vial sizes—5mg and 10mg move fastest for us, the 15mg vials we usually have but maybe check lead time if you need over 50 units or so, we ship with cold chain packaing since it's required for teh lyophilized powder to stay stable at 2-8°C.

Basically what you're getting is a ≥99% purity peptide that holds up well across different storage conditions as long as you keep it in the fridge and away form direct light, we've handled thousands of vials and the white powder consistency is remarkably uniform batch to batch, better than some comparable GLP-1 compounds we've tested.

Most buyers go with the 10mg vials for their research protocols, I think it's a sweet spot for dosing flexibility—you can reconstitute it with sterile water at 5mg or 10mg depending on your batch needs, but it's not suited for direct human or animal use no matter how you prep it, just an fyi.
One thing you might not expect—even with pharmaceutical-grade purity, the 4113.64 g/mol molecular weight means it takes a careful dissolution technique to avoid clumping, so use a slow dropwise method when reconstituting (usually works best with bacteriostatic water, around 2-4°C to start).

2023788-19-2 is the CAS you'll want for any SDS procurement though honestly we can provide that and COA on request within a day or two, we usually have roughly 200-300 vials of the 10mg on hand at any time.
