Tirzepatide Costco Manufacturer - GMP Certified Diabetes/Obesity Research Peptide

So the main thing we’ve found is that buying across a tier makes a real difference—sample pricing sits at $18 per mg, mid-volume at $12, and bulk at $8.50, which is basically half what some small orders run, and we usually have stock on the 10mg and 20mg vials ready to ship within 20 days or so.

It’s a lyophilized white powder, CAS 2023788-19-2, with ≥99% purity run through HPLC—pretty tight specs for research, and teh 4813 molecular weight means it’s stable longer at 2-8°C if you keep it away form light, which is a detail buyers handling obesity or diabetes studies don’t always think to check about degradation rates.

We add a COA for every batch, and an optional third-party test if you want it, but honestly it’s overkill for most labs; the GMP process already includes mass spec and amino acid analysis, so workability is good for binding assays or cell-based work. It’s not suited for anything oral though—only injection or reconstitution—and we don’t hide that.

Custom packging is doable up to the MOQ—you can get 1mg vials for smaller doses or 60mg for bigger studies, and the tolerances are better than generic supply for this peptide, especially if you’re running dose-response timing in a 30mg format.

: our company have to confirm lead time on orders over 500 vials (usually 50 units or so mid-range), but simple bulk is faster—just tell us vial count per pack and we’ll setup the drum or box accordingly, and remember it’s 2-8°C on arrival.
