So you're looking at the dual agonist that's been getting a lot of attention—the one with teh CAS 2023788-19-2, and basically it's a 39-amino acid peptide that hits both GIP and GLP-1 receptors. We've been moving this for a few years now, and what it does is it gives you that combined pathway activation that's been showing better glucose control and weight management outcomes in studies compared to older single-target ones. The molecular weight is around 4813 g/mol, and you'll get it as a white powder that's soluble in DMSO, not water, so keep that in mind for your reconstitution protocols.
Most buyers go with the 10mg or 15mg vials for their in vitro work, but we also see labs ordering the 30mg when they're running longer. It's pretty much a pharmaceutical-grade matrial at 99% purity, and we always include the COA with each batch—HPLC-verified, so you can see the impurity profile yourself. One thing that catches people off guard is the storage requrement: it needs to be at -20°C, and if you let it sit at room temperature for more than a few hours, you'll start losing activity. We usually have stock, but confirm lead time if you need more than 50 vials or so.
The 5mg is better for smaller pilot studies or if you're just testing a new assay setup, but honestly, the 15mg is the sweet spot for most repeat buyers. And we do offer bulk pricing once you hit 100 units or more—just ask for a quote on that, because the per-vial cost drops significantly. Lead time is typically 7 to 14 business days for standerd orders, though we've had rush orders ship in 5 days when the inventory was right.
You'll see this referred to as LY3298176 in older literature, and the EC number is 200-001-8 if you need that for your documentation. It's not suited for anything beyond research use—we don't supply it for human consumption, and the purity is fine for lab work but it's not formulated for injection in living subjects. One detail that's easy to overlook: the powder is hygroscopic, so after you open the vial, use it quickly or store it under inert gas.
Also, some buyers ask about solubility in things other than DMSO, but honestly, DMSO is your best bet for consistent results. We've had people try ethanol or PBS, but the solubility drops off fast, and you'll get precipitation at higher concentrations. The shelf life is over 2 years when stored properly at -20°C, but we recommend using it within 6 months after reconstitution (usually 2-4 weeks if you're aliquoting and freezing). Anyway, that's the gist of what most people need to know before ordering.
Yes, absolutely. We can share the COA with every batch — it includes HPLC purity results, appearance check, and molecular weight verification. Just request it with your order.
Our MOQ is typically 10 vials per concentration, but we can flex that for first-time orders or larger commitments. Reach out and we can work something out.
It's packaged in sterile, sealed vials with a desiccant pouch inside a foil bag, then boxed. This keeps moisture out and maintains stability for over 2 years at -20°C.
We can custom-fill other concentrations for bulk orders, but our standard line covers those four. If you need a specific dose, let us know the volume and we'll quote it.
We supply a batch-specific COA, MSDS, and a statement of pharmaceutical grade purity. If you need additional documentation for import or compliance, just ask and we'll prepare it.
