We've been shippng this QSC Semaglutide to labs doing metabolic work for a while now, and most buyers go with the 10mg vials for their dose-response studies. Actually, teh 5mg is better if you're testing lower ranges, but the 30mg gives you more flexibility without needing to reconstitute as often.
Purity runs at 99% by HPLC, which is tighter than what you'd get from most generic peptide suppilers—that matters when you're trying to avoid off-target effects in GLP-1 pathway work. CAS is 2381089-83-2, and it shows up as a, pretty much what you'd expect for a research peptide of this class.
It's not suited for anything beyond lab use, obviously—no in vivo human work. We usually have stock on the 10mg and 20mg vials, but the 5mg and 30mg may need a week or so lead time. Storage is just a cool, dry place away from light, nothing fancy.
What it does is mimic GLP-1 signaling pretty well in cell-based assays, and the 99% purity keeps batch-to-batch variability low. You'll get 10 vials per kit, and we include COA with each shipment. And one thing buyers don't always think to ask: the vials are pre-scored for clean reconstitution with sterile water or buffer.
The lyophilized cake is surprisingly sturdy—handles shipping at room temp fine for a few days, though we recommend refrigerated transport for longer transit. Anyway, we've had labs get good data on glucose uptake and insulin secretion from this batch. Roughly 50 units or so is our MOQ, but our company can split kits if you're just starting a pilot.
We can start with as low as 1 kit (10 vials) per order. For larger quantities, we offer volume pricing — just reach out to discuss.
Yes, a COA is included with every shipment, confirming the 99% purity and pharmaceutical grade. HPLC and mass spec data are available on request.
Standard orders ship within 3-5 business days after payment confirmation. Express shipping takes 5-8 days, and we'll provide tracking once it's on the way.
For the 30mg vial, we recommend adding bacteriostatic water to reach your desired concentration — common practice is 1mL for a 30mg/mL solution. Store the reconstituted solution in the fridge and protect it from light.
We ship in plain, unmarked boxes with no product labels on the outside. For temperature-sensitive orders, we can include ice packs on request — just let us know at checkout.
