QSC Tirzepatide Factory Supply 99% Purity Peptide for Research Use

You're probably looking at a few different sources, and what matters most is what happens after it leaves the line—we run full HPLC, and we keep the raw data on file for at least three years, so if you ever need to trace a lot back to a specific synthesis run, our company can pull it up in about an hour or so.

Most buyers in this space are running metabolic pathway work or receptor binding assays, and the 99.9% purity means you're not chasing ghost peaks form truncated sequences or residual solvents—we've had labs tell us their are tighter than with some other supliers they'd tried.

Teh white powder comes in 30mg vials with a rubber stopper and flip-off seal, and we store everything at 2-8°C in a light-protected cold room before shiping, but here's the thing—once you reconstitute it, you've got about 24-48 hours at 4°C before you start seeing degradation, so plan your aliquots accordingly.

Batch consistency is where we actually shine, because we don't just give you a COA and call it done; we also offer a full retest policy within 30 days of receipt if you run your own HPLC and find something outside spec—basically, if your numbers don't match ours, we'll take it back and replace it, no questions asked.

446036-97-1 is CAS number you'll see on the vial label, and the molecular weight is roughly 4113 g/mol, but what that means in practice is that the peptide backbone holds up well under typical assay conditions—better than some GLP-1 analogs we've handled that tend to aggregate at higher concentrations.

One thing that catches first-time buyers off guard is that this isn't suitable to any in vivo work in humans—it's strictly for research use only, and we don't supply it with any clinical-grade certifications, so if your protocol involves anything beyond cell-based or animal models, you'll need to look at a different grade entirely.
