Factory Supply Tirzepatide 15mg - 99.9% Purity Weight Loss Peptide Powder

Basically what we're getting is a dual GIP/GLP-1 agonist that hits both pathways at once, and from the HPLC data it's coming in at 99.9% or better — that's tighter than most single-agonist peptides we've sourced for lab work, and the batch-to-batch consistency on the COAs we've seen so far is actually pretty good.

The molecular weight is 4813.5 g/mol, CAS 2023788-19-2, and it's a white powder that we'll store at 2-8°C in the dark (we usually have stock on the 10-vial boxes, but confirm lead time — sometimes it's 20 days or so depending on their production cycle). 99.9% purity by HPLC is what they guarantee, and we get a full COA with each batch, though I'd still run our own QC on first order.

It's pharmaceutical grade, but let's be clear — this is strictly for research use only, not for human or veterinary application, and the 15mg dosage is better suited for in vitro studies than for anything involving long-term metabolic modeling. Most buyers go with the 10mg vials for smaller assays, but the 15mg gives you a bit more flexibility if you're running.

One thing I noticed from handling a previous batch: the powder is hygroscopic, so you'll want to aliquot it imediately after opening and keep the vials sealed under inert gas if possible — that's a detail the spec sheet doesn't mention but matters for long-term stability. Also, they offer a retest policy at 12 months, which is standerd for this grade, but we usually verify within 6 months anyway.

The packaging is 10, each at 15mg, and the MOQ is typically 2 boxes for this supplier — though our company can negotiate if we're ordering alongside other peptides form their catalog. 2-8°C storage is non-negotiable, and they recommend protecting it from light, so the amber vials help there.
