Actually, we're sitting on about 200 grams of the lyophilized powder right now, and it tests well above 99% by HPLC—usually around 99.3% or so on the latest batch. That triple receptor agonist profile means you're hitting GIPR, GLP-1R, and glucagon all at once, which is pretty much the whole point for metabolic studies.
Most buyers go with the 50mg or 100mg vials for easier handling, but our company can do custom quantities if you need more—just check lead time, since it's not always on teh shelf. The white powder dissolves cleanly in water or buffer, no clumping, which is a detail you'll appreciate when you're prepping doses.
We usually have stock, but confirm lead time if you're ordering over 500mg—there's a slight lag sometimes. Storage is straightforward: 2-8°C, keep it dark, and you'll get the full 24 months of stability out of it.
One thing to note—it's not ideal for oral gavage studies without proper encapsulation, as the peptide degrades pretty fast in acidic conditions. For receptor agonist work in vitro or in vivo, it's better than reagent-grade analogs we've seen elsewhere.
CAS is 2381089-83-2, MW is about 4116 g/mol—give or take—and the COA form our last batch shows no detectable impurities above 0.5%. Just let me know quantiy you're after, and I'll get you a quote with shippng times.
