High Purity Tirzepatide Peptide 99% Freeze-Dried Powder for Weight Loss Research

So you're looking at this for metabolic research, and what it does in practice is mimic two gut hormones—GIP and GLP-1—which basically tells the body to slow gastric emptying and signal satiety, and that's why it's been getting so much attention in weight management studies.

Purity is over 99% by HPLC, which matters because even small impurities can throw off your in a 15mg vial, and we typically see a molecular weight of 4813.5 g/mol with a sequence that includes that N-epsilon-octadecanoyl-gamma-Glu modification on teh lysine—that's lipid tail that gives it its extended half-life.

Most buyers go with the 10mg or 20mg vials for their protocols, and we usually have stock on those, but the 2mg and 5mg are better suited if you're running pilot studies or titration experiments.

Storage is pretty straightforward—keep it at 2-8°C in the dark, and you'll get about 24 months of shelf life, but honestly, if you reconstitute it with sterile water for injection, use it within 20 days or so once it's in solution.

One thing that catches people off guard: this is research grade only, so it's not for human use, and we don't recommend it for anything beyond in vitro or animal work—definetly not for clinical trials without further purification.

For ordering, just let us know which strength you need—2mg through 20mg—and we ship in boxes of 10 vials, with lead time usually 2-4 weeks depending on batch availability, and we include the COA with every shipment.
