Inquiry
We’ve been getting a lot of inquiries about consistency in peptide research lately, especially with semaglutide batches varying from supplier to supplier. Our raw semaglutide powder comes in at ≥99% purity by HPLC, and we run a full COA on every lot—so you’ve got the numbers if you’re doing dose-response work. It’s a white powder, pretty much what you’d expect, and the CAS is 910463-68-2 if you need to cross-reference.
For storage, keep it dry and dark—0 to 4°C works for short-term use, like a few days or weeks, but -20°C is better if you’re sitting on it for months or years. Shelf life is over two years when stored properly, though we usually have stock ready to ship, so confirm lead time if you need a rush. The molar mass is roughly 4113.57 g/mol, and it’s soluble in water with the right formulation—basically, you’ll want to check your buffer system.
One thing we don’t push it for is direct in vivo work without formulation development; it’s research grade, so it’s not suited for clinical use or personal consumption. But for metabolic or weight management studies, the purity holds up batch to batch—tighter tolerance than some generic peptides we’ve seen on the market. Most buyers go with the 5g or 10g size, and we can do custom packaing if your protocol calls for something specific.
Also, we offer OEM on the powder if you need it in a different format—lyophilized or pre-weighed vials, for instance—but that adds about 20 days or so to the timeline. The MOQ is typically 1 gram for standard orders, though our company can negotiate for larger bulk runs. We’ve got COAs and TDS on file for every batch, and if you want a retest after six months, just ask—we can arrange it at cost.
Logistics-wise, we ship form our facility, and most orders go out within 3-5 business days after the quality check clears. It’s a dry powder, so no special hazmat fees for domestic shipments, but international buyers should check their customs rules—we’ve had a few delays with certain countries. That’s about it for teh specs; anyway, let us know if you need a sample batch to run your own HPLC on.
We can do as little as 1 gram for sample orders, but for wholesale pricing we typically ask for 10 grams or more. Bulk discounts apply at higher volumes.
Yes, we supply a COA with every order showing the ≥99% purity, appearance, and other key specs. Third-party testing reports are available on request.
Keep it in a dry, dark place. For short-term use (days to weeks), store at 0–4°C. For long-term storage (months to years), -20°C is best. Properly stored, it stays stable for over 2 years.
Absolutely, we offer customized packaging and labeling for bulk orders. Just let us know your requirements, and we'll handle it.
For standard wholesale orders, lead time is usually 5–10 business days after payment confirmation. Rush orders can be arranged if needed.
