We're confirming teh custom Tirzepatide order for the Costco supply chain, CAS 2023788-19-2, at 99% purity or better — that's the spec we hold to across all batches, and the white powder form is standdard for this kind of research.
It's not for human use, obviously, but for metabolic and diabetes studies it's pretty much go-to right now, and the molecular weight sits at 4813 with that long C225H348N48O68 formula, which matters for dose calculations.

Storage is a hard requirement at -20°C and protected from light, so make sure your lab has that locked in — we usually have stock, but confirm lead time for the custom packging (vials or bulk containers, depending on what you need).
Most buyers go with the 50mg or 100mg vials for smaller studies, but our company can do bulk if you're scaling up, and the COA will be included with each shipment.

Actually, one thing that catches people off guard is the shipping timeline — it's about 15-20 days or so for customs clearance, especially if you're outside the US, but we handle all the import docs to smooth that out.
Anyway, the order is placed, and we'll send the tracking once it's dispatched.
We don't enforce a strict MOQ for research-grade Tirzepatide. You can start with as little as 1 gram if you're testing, and we'll scale up from there for larger projects. Just let us know your target quantity when you request a quote.
Lead time depends on the packaging customization — standard vial orders usually ship within 5-7 business days after payment. Bulk container orders might take a bit longer, but we'll give you a precise timeline once we confirm the specs.
Yes, we include a COA with every batch showing HPLC purity results, molecular weight confirmation, and appearance data. Just request it at the time of order, and we'll send it along.
You'll need to keep it at -20°C in a freezer, and protect it from light — so an opaque container or foil wrap works. Under those conditions, the powder stays stable for at least 12 months. We can also suggest specific packaging if you're planning long-term storage.
Absolutely — we offer customizable options including sterile vials, bulk containers, or any format you require. Just tell us your preferred size and material, and we'll adjust the packaging to fit your workflow.
