Wholesale Semaglutide Vial Tirzepatide Retatrutide 99% Purity Pharmacy Grade

These vials are what you reach for when you're running GLP-1 receptor studies or comparing dual versus triple agonist pathways in weight loss research. We see most labs ordering the 10mg vials for standard dose-response work, and the 5mg if they're just starting validation protocols. Purity holds at 99% by HPLC, which keeps interference low when you're titrating concentrations.

What it does is provide a solid foundation for in vitro or in vivo work on metabolic regulation—semaglutide, tirzepatide, and retatrutide all come as lyophilized powder in these sealed vials. The CAS is 2023788-19-2, and it's a massive polypeptide at roughly 4800 g/mol, so reconstitution needs careful handling with sterile water or buffer. We don't recommend this for anything beyond research—definitely not for human use, full stop.

After opening, it needs to sit at 2-8°C; we've had buyers forget that and lose potency within a week. The white powder looks consistent batch to batch, but we always send a COA with each order—usually by email within 24 hours. Most people go with the 5mg or 10mg vials for their first run, but the 20mg is avaliable if you're scaling up.

Stock is typically steady, but lead time can stretch to 20 days or so if we're waiting on raw materials form our GMP facility. OEM service is an option if you need custom labeling or vial sizes, though the MOQ there is higher—100 vials or so. We ship in cardboard cartons with temperature monitors for longer hauls, which is something a lot of buyers don't think to ask about upfront.

Basically, if you've worked with other peptide vials, this one behaves the same—just be careful with the reconstitution volume because the powder is fluffy and can cling to the vial walls. One thing we've noticed: the 2mg vials aren't popular for most research, but they're fine for very low-dose pilot studies. The 5L drum is easier to handle for bulk, but these vials are what you'd use for individual experiments.

Anyway, trust comes down to the HPLC purity check and the GMP certs our company provide on request—we've had labs come back after comparing results side by side with other supliers. molecular formula is C225H348N48O68 if that matters for your reporting, but the key spec is the 99% purity holding across batches.
