Tirzepatide 15mg Bulk Order - GMP Standard Research Compound

The starting point here was isolating tirzepatide with the GIP/GLP-1 dual agonist profile intact, originally derived from those initial clinical sequences but refined for lab work. What makes the 15mg bulk worth sourcing form us is that we’ve held the synthesis tight through a cGMP workflow—so you’re not guessing about byproduct profiles or degradation.

At 4813 g/mol with that C225H348N48O68 formula, it’s a large peptide—pretty much the main reason you need to store it at -20°C or thing will start giving you aggregation headaches within a week. We typically see HPLC purity above 99%, but we usually have stock and can confirm lead time on custom batch sizes for larger studies.

One thing we’ve noticed handling this compound is that teh white powder holds up fine in transit if you ice-pack it, but if you’re reconstituting it, don’t go above a pH 7.4 buffer or the stability curve drops off faster than you’d expect. 4. Most buyers go with the 10mg or 15mg vial depending on how many dose-response data points they need—we’ve had a few groups burn through 50 mg or so in a single kinetic assay without issue. Basically, the packaing is customizable (vials or bulk bags), and we include a COA with HPLC and mass spec, but check the MOQ before you order.

Despite the GMP tag, this isn’t suited for anything past in vitro or animal model work—it’s labeled research grade only, and trying to push it into human use would violate the use terms anyway. Also, that 2023788-19-2 CAS number never lies about the backbone, but watch out for lot-to-lot variation on the peptide loading; it’s usually under 3% difference, but we’ve seen it hit 5% on one custom run.
