We got your RFQ on the semaglutide and can do custom vial sizes—5mg, 10mg, 15mg, and we’re set up for bulk in 1g or 2g vials as well, so let us know what works for your protocol. Purity runs 99% by HPLC, white powder as you’d expect, and the CAS is 2023788-19-2. Storage is 2-8°C in a dry, dark spot—pretty standerd for this peptide, and shelf life holds at 24 months if you keep it sealed.
Most buyers go with the 10mg vials for routine reconstitution, but we’ve had requests for smaller sizes too when testing. It’s basically a GLP-1 agonist with that Aib substitution at position 2, so it resists DPP-4 degradation better than liraglutide or the older analogs.
The molecular weight is 4813.5 g/mol, and what it does is bind albumin via that fatty acid chain on Lys-26, which stretches its half-life to roughly 7 days in vivo. Not suited for acute dosing studies—it’s more for extended work, like chronic exposure models or stability testing over a week or so.
One thing we’ve seen in handling: powder is hygroscopic, so open it in a dry enviroment under inert gas if possible. TDS and COA come with each batch, and we usually have stock in 7-10 days, but check lead time for teh 15mg size—that one moves slower.
Anyway, if you need custom labeling or a different concentration on the bulk synthesis, our company can do that—just say the word on the RFQ. Our MOQ is 50 vials for the 5mg and 10mg, but the 1g size can go single vial if you’re in a pinch.
We can do single vials for most sizes, so MOQ for 1g or 2g is just one vial. If you need bulk pricing, just let us know the quantity.
For in-stock items, we usually ship within 1-3 business days after payment clears. Custom or larger orders might take 5-7 days.
Yes, we include a COA with every batch showing HPLC purity results, so you can confirm it's 99% white powder as specified.
Keep it at 2-8°C in a dry, dark place—like a fridge. Avoid moisture and light, and it'll stay stable for the full 24 months.
We can discuss custom packaging for larger research projects, but standard sizes are 5mg, 10mg, 15mg, 1g, and 2g vials. Just reach out with your needs.
