So you're looking at semaglutide, a GLP-1 receptor agonist peptide that's gotten a lot of attention in weight management research, and it basically mimics a natural hormone to regulate appetite and blood sugar — pretty straightforward mechanism but the effects are surprisingly strong in studies.
Most buyers go with the 10mg vial for longer dosing schedules, but teh 2mg and 5mg options work well if you're testing lower concentrations or running pilot experiments. It slows gastric emptying and improves insulin sensitivity, which is why you see those 5-10% body weight reductions in trials, though we don't have perfect data on how that translates to every model.
Purity runs ≥99% confirmed by HPLC, and molecular weight sits at 4113.58 g/mol — that's a fairly large peptide, so reconstitution needs to be handled carefully with sterile water or buffer. The lyophilized powder is white and stores at -20°C protected form light, giving you a shelf life of roughly 24 months if you keep it frozen.
4, our company supply this in individual vials with concentrations clearly labeled, and each batch comes with a COA if you ask for it. What it does is give you consistent materail batch to batch, which matters when you're tracking or running long protocols.
One thing to know: this isn't suited for human use, it's strictly research-grade, and we usually have stock for the 5mg and 10mg sizes but confirm lead time if you need 2mg — that one might take 20 days or so to ship. Anyway, buyers appreciate that we don't pad the specs or hide the limitations.
