XCE Tirzepatide White Powder 2mg/5mg/10mg Vials - Research Chemical

The >99% purity on the HPLC is the first thing that grabs anyone’s attention, but what seals it for us is the batch-to-batch consistency—we've run three separate lots now and peptide maps overlay almost perfectly, so you’re not chasing variability between orders.

Storage is straightforward if you plan ahead: -20°C for anything beyond a month or so, and 0-4°C works fine for the daily pulls as long as you’re not leaving it out of the fridge for hours. We usually stock enough for 90 days at a time and keep it in a dedicated freezer.

The vial sizes actually simplify dosing for different protocols—we predominantly order the 10mg vials for our standdard assays, but a few of the guys running pilot studies prefer the 2mg to avoid excess reconstitution waste. It’s a small thing, but it saves time.

Lead time is typically 10-14 business days form order to dock, though the last shipment took closer to 18 (check with the suplier before committing if you’re on a tight timeline). They’ve been good about providing a COA with every batch, which we always insist on.

We learned the hard way not to trust ambient storage claims—this stuff degrades noticeably after 3-4 days at room temp, even in a desiccator. The -20°C rule isn’t just marketing speak; it’ll easily clear the 2-year shelf life if you respect it.
