We're looking at 20mg vials of semaglutide, GLP-1 receptor agonist that's been central to a lot of metabolic research lately, and it come as a with purity listed at over 99% which is pretty standerd for pharmaceutical grade—the molecular weight is roughly 4113.6 g/mol and it have a 24-month shelf life if you keep it at -20°C and protect it form light, though you'll want to confirm lead time on that.
Most buyers are using this for weight management or appetite regulation studies, not for anything clinical obviously since it's research use only, and what it does is mimic the natural GLP-1 hormone to influence insulin secretion and satiety signals—basically it's not suited for diabetic treatment work outside of a lab setup, so we usually see it in metabolic disorder investigations or diabetes-related cell models.
The 20mg per vial is actually a tighter tolerance than some other suppliers, and we've got the COA from HPLC, though I'd still recommend checking the purity batch-by-batch on your end since storage conditions during transit can vary—also, the lyo cake appearance can sometimes fluff up more than expected if the vacuum seal is compromised, but that's a rare edge case.
And when ordering, our company can usually do an MOQ of five vials or 10 vials depending on your batch, with a typical lead time of 20 days or so (usually 2-4 weeks), and teh packaing comes in individual vials which keeps contamination risk low—just make sure your freezer space is ready for -20°C storage right away since it degrades fast above that, in most cases within hours if exposed.
One detail that might not be obvious is that the shelf life is only valid if the vial stays sealed and away from moisture—once reconstituted, you're looking at maybe a week or so at 2-8°C, and repeated freeze-thaw cycles will kill the activity, so plan your aliquoting accordingly.
Also, we've had a few buyers who thought this could work for in vivo dosing without buffer adjustments, but the lyophilized powder needs proper reconstitution with sterile water or a specific vehicle, and the pH sensitivity can mess up results if you're casual about it—better than reagent grade for this appliction, but it's not plug-and-play.
We don’t have a strict MOQ — you can order as few as 10 vials for small research batches. For larger orders, just reach out for bulk pricing.
Orders usually ship within 3-5 business days after payment clears. If you need it faster, let us know and we can often rush it.
Yes, every batch comes with a COA showing the >99% purity, mass spec, and HPLC results. Just request it with your order.
Keep them at -20°C in a freezer, away from light. Once reconstituted, use immediately — don’t refreeze. Proper storage ensures the full 24-month shelf life.
Absolutely — we can adjust the vial fill amount (e.g., 10mg or 50mg) and add your custom label or lot number. Just give us the specs when you order.
