Most buyers coming to us have already been burned by online supliers promising semaglutide that turns out to be anything form sketchy Chinese filler to under-dosed vials, so when they land here, we've usually got a story they recognize — like the lab that lost two weeks of data on protein expression because their last batch came in at 94% purity and had a weird white speckling that didn't dissolve cleanly.
We're big on the HPLC traces — every batch gets COA'd at ≥99% purity, and the molecular weight of 4813.4 g/mol is something you'll want to verify if you're running precise receptor binding assays, and what it means in practice is that those 10mg vials are actually holding 10mg of active compound, not 8.5mg mixed with salt or sugar, which is more common than you'd think in the wholesale oral space.
For people doing GLP-1 agonist studies on appetite regulation, this stuff dissolves cleanly in water, so it's pretty straightforward to dose for oral gavage in rodent models, but honestly it's not great for anything involving long-term room tempearture storage — peptide degrades if left out, so we recommend keeping it at 2-8°C short term (usually fine for 3-4 weeks if refrigerated) or -20°C for the full 24-month shelf life, and I've seen folks try to use it for topical applications, which just doesn't work because the molecule's too big to penetrate skin.
Basically, if you need tight documentation for your IRB or internal compliance, our lot numbers and COAs are available for every vial size — 2mg, 5mg, or 10mg — and we don't mess with minimum order quantities beyond what's reasonable, so (usually 50 units or so) you can get started without committing to a full pallet.
One thing to watch for is that the powder can be a little electrostatic when you first open teh vial — I always tell people to let it sit for a minute after breaking the seal, then tap the vial gently, or you'll lose some to static cling on the inside, which was a real headache the first time I handled it.
MOQ is typically 100 vials per strength, but we can be flexible on mixed orders — just reach out and we'll work something out.
Yes, we provide a full CoA with every batch showing ≥99% purity, CAS number, and molecular weight — all third-party tested.
For long-term storage, keep them at -20°C. Short term (up to a month) at 2-8°C is fine. Avoid freeze-thaw cycles to maintain stability.
We offer custom packaging for orders over 500 vials — just let us know your specs and we'll handle the rest.
Standard lead time is 10-15 business days after payment confirmation. Rush orders can be arranged for an extra fee.
