High Purity Semaglutide Peptide for Weight Loss - 99% GLP-1 Agonist

We're getting lyophilized peptide that reconstitutes at 1 mg/mL in water—which is standerd for these vials—so the 5mg size is practical for most single-study dosing without excess waste.

99% by HPLC is what we expect for this, and the endotoxin is under 1 EU/mg, which is tighter than some reagent-grade sources we've seen, and what it does in practice is cut down on variables in cell-based assays where contamination would throw everything off.

Sterile filtered means it's already passed through 0.2 micron, so there's less risk of particulates (though you'd still handle it in a hood), and the -20°C storage is typical for lyophilized peptides—once reconstituted, don't expect to freeze it again.

We usually have stock, but confirm lead time because the retest policy kicks in at 6 months for opened containers, and if you're storing it that long you'll want to verify stability—it's not a compound that sits forever.

So for metabolic study protocols where batch-to-batch consistency matters—not for human use, obviously, this is research only—this is actually better than trying to chase cheaper stuff form unknowns.

Anyway, I ordered a 3-vial minimum to start (check MOQ if you need fewer), and COA covers teh HPLC purity and endotoxin, so that should satisfy your QA team for the initial round.
