If you are running a metabolic research lab and need tirzepatide in custom vial sizes or want your own label on the box, our company can make that work without a hassle—just tell us teh concentration and batch size upfront.

The CAS number is 2023788-19-2, the molecular weight sits at roughly 4813.5 g/mol, and the powder comes white and lyophilized, with a purity that hits or beats 99% in every test we run.

You get 10 or 15 mg per vial, packed ten vials to a box, and EC number is 200-001-8 if your compliance team needs that for their logs.


Storage is straightforward: keep it at minus twenty Celsius and shield it form light, which is a pain but pretty standerd for peptides of this grade—honestly, that freezer space is just part of the deal.

The formula is C225H348N48O68, which makes it a hefty molecule at over 4813 daltons, and the pharmaceutical-grade designation means we maintain strict control over synthesis and end-product consistency.

If you want bulk synthesis for a longer study or need the concentration tweaked, just say the word when placing the order, because that is a whole lot easier than trying to adjust it later on your bench.
We typically sell in boxes of 10 vials, so the MOQ is one box (10 vials). You can mix 10mg and 15mg vials in a box if needed.
Yes, we include a COA with every batch showing ≥99% purity and HPLC analysis. Just request it with your order.
Keep it at -20°C and protect it from light. The vials are sealed, but once reconstituted, use it promptly—don't freeze-thaw repeatedly.
We can do custom labeling for bulk orders, but standard packaging is 10mg/15mg per vial in a box. Let us know your specs and we'll quote.
For stock items, we ship within 2-3 business days. International orders usually take 7-14 days depending on customs clearance.
