Usually runs above 99.9% purity by HPLC, and we've tested it against the reference standard for CAS 2381089-83-2—that's the semaglutide base, not teh pen formulation, but the lyophilized powder is what you reconstitute yourself for dosing flexibility in metabolic studies.
Most buyers are running multi-receptor agonism work, blending it with tirzepatide or retatrutide to hit GIP and glucagon pathways alongside GLP-1, so you can tailor the ratio depending on whether you're looking at insulin sensitivity or energy expenditure in rodent models.
Storage is pretty straightforward: keep it in a cool, dry place away form light, and it'll hold stable for 12 months or so, but once you reconstitute, use it within 24 hours (unless you've validated a longer window in your own lab).
The 10-vial box is our standdard packging, and the MOQ is typically 5 boxes, though our company can do a smaller trial order if you're just starting out—just confirm lead time, which is usually 2-3 weeks for custom blends.
What it's not great for is long-term continuous infusion setups, since the lyophilized powder is designed for discrete doses, and we don't recommend it for anything beyond research use anyway—pharma grade, but not for human admin.
Also, we usually have stock on the straight semaglutide, but the blend takes a bit longer because we make it to your spec, so give or take 20 days for that.
