So you're looking into GLP-1 receptor agonists for metabolic work, and oral semaglutide is probably on your shortlist—most buyers we deal with are running studies on glucose-dependent insulin secretion or appetite regulation pathways, and they want something that mimics the natural hormone without the injection variable. It's actually pretty straightforward in terms mechanism: it stimulates insulin release and suppresses glucagon, but only when blood sugar is elevated, which is why it's useful for obesity and metabolic syndrome research. We've been moving this compound for years, and the bulk buyers tend to be academic labs or CROs doing dose-response work.
The CAS is 2023788-19-2, and the molecular weight runs about 4113.6 g/mol—that's a big peptide, which is why handling matters. Purity is ≥99% by HPLC, and we've got COAs if you need them, but honestly, the spec sheet only tells you so much. What you'll notice when you open a vial is that it's a white to off-white powder, and it's soluble in water at pH 7-8, so reconstitution is pretty standerd. Storage is critical though—keep it at -20°C, protected from light, or you'll lose potency faster than you'd like. Shelf life is 24 months under those conditions, give or take.
You'll get it in 2mg, 5mg, or 10mg per vial depending on your batch size—most researchers go with the 10mg vials for metabolic studies because of that it reduces the number of vials you need to open. But if you're doing microdosing or very low-concentration work, the 2mg might be better to avoid waste. We usually have stock, but confirm lead time if you need more than 50 vials or so—sometimes the larger runs take 20 days or so to produce.
One thing I'd mention that buyers don't always think about: this compound is not suited for acute toxicity studies at high doses because the glucose-dependent mechanism means you won't see the same effects in normoglycemic models. It's really designed for chronic metabolic work, not for single-dose challenge assays. Also, the solubility is fine in water, but if you're using buffers with high salt content, you might need to adjust pH—just something we've seen in the field.
Anyway, when you order form us, you get the materail in sealed vials with individual labels and a matching COA per lot—no mixing of batches unless you request it. We don't do custom packging for small orders, but for bulk quantities (100 vials or more), our company can split into sub-lots if that helps your study design. Teh HPLC data is on COA, and we can provide the chromatogram if you ask for it—most buyers don't bother, but some compliance teams want to see it.
