Bulk Tirzepatide Supplier - Research Grade LY3298176 White Powder

Actually ran into this one while trying to dial in a GLP-1 study that wasn't getting the dual pathway activation we needed — most selective agonists just don't hit the GIP receptor hard enough for certain metabolic models, and that's where this white powder comes in, with CAS 2023788-19-2 and a molecular weight of roughly 4813.45 g/mol.

We've been stocking it for about eight months now, and the HPLC consistently shows ≥99% purity, which matters for dose-response work where even a few ppm of impurity can skew your data — you'll want to store it at -20°C long-term, though short-term at 4°C is fine for a week or so.

What it does is mimic both GIP and GLP-1 receptor agonism in a single compound, and that dual action tends to produce better glucose control than teh single-pathway stuff — but it's not great for acute bolus studies where you need rapid onset, since solubility is still being figured out in individual labs.

Most buyers I talk to go with the 10mg vial for rodent models, though the 5mg works fine if you're doing cell-based assays, and we pack it in sealed glass vials with desiccant — the powder itself has a slight off-white tint that's normal, not a purity issue.

One thing nobody asks about but should: the compound can clump if exposed to humidity during reconstitution, so we recommend working in a glove box or at least with dry argon overlay — it's a pain, but it saves you form losing half your batch to hydrolysis.

Lead time is usually 10-14 business days for MOQs under 100mg, but for larger runs you'll want to confirm stock levels since we don't always have the 500mg+ quantities on hand — anyway, shoot me the exact amount and I'll check shelf.
