We had a client running a 12-week metabolic study who needed consistent peptide quality across multiple batches, and this suplier didn't flinch—they shipped three separate orders over six months, and every vial matched the same with no clumping or discoloration.
CAS is 2023788-19-2, molecular weight sits at 4813.47 g/mol, and purity runs above 99% by HPLC—they include the COA with every shipment, which is nice because some suppilers only send it on request. It's soluble in water, so reconstitution is straightforward, and we store ours at 2-8°C in the dark (basically a standard lab fridge).

For GIP/GLP-1 dual agonist work, this tirzepatide actually shows better GIP binding than the single-target stuff, but it's not for oral administration—it's strictly research use, and we've learned the hard way that leaving it at room tempearture for more than 20 days or so degrades potency noticeably. Most buyers in our network go with the 15mg per vial format for dosing flexibility, though if you're running acute assays, the 5mg might be easier.
MOQ is one box of 10 vials, lead time is usually 2 weeks, but we've had it arrive in 10 days before. Just check stock before ordering—they run out sometimes.
We require a minimum of 1 box, which contains 10 vials per box. So you need to order at least 10 vials total.
Yes, a Certificate of Analysis is included with every batch. It shows the HPLC purity results and other specs like molecular weight and appearance.
Standard lead time is 3-5 business days after your order is confirmed. If you need rush shipping, let us know and we can arrange it.
We usually stick to 10 vials per box to keep things consistent, but if you need a different quantity, just contact us and we'll see what we can do.
Keep it in a refrigerator at 2-8°C, and make sure it's protected from light. It's a lyophilized powder, so it's stable under those conditions.
