It's got a purity rating of 99% or better, which for this type of research peptide is basically the — you're not chasing impurities when you're running assays on GLP-1 receptor activity. Most labs we deal with won't touch anything below 98% for metabolic work, so this clears that bar comfortably.
The powder comes as a white to off-white solid, and what we've found is that consistent particle size across batches makes reconstitution far less of a headache. You'll want to keep it in teh fridge short term, around 2-8°C, but for anything over a few weeks we usually recommend -20°C to be safe. Shelf life is north of 2 years if you follow that.

910463-68-2 is the CAS number, molecular weight clocks in at 4113.57 g/mol — it's a big molecule, about 187 carbons, so solubility in standdard solvents can be tricky if you don't pre-wet it properly. We typically see buyers use it for endocrinological studies, not for anything involving cell culture at higher concentrations.
Packaing is pretty flexible: you can get it in drums or bags, and they'll do custom sizing if you need it. They provide COA and MSDS with every order, though turnaround time is usually 20 days or so. What's nice is the MOQ isn't punishing — you can start with a smaller batch to validate before scaling up.
