Most buyers looking at this are running metabolic studies past basic GLP-1 agonism—they need dual agonist data without the nausea ceiling semaglutide hits, and this is where retatrutide actually shines for weight reduction protocols; we've seen labs push past 24% mean weight loss in obese models using 10mg dosages or so.
It's a white powder, >99% purity on our last 40 COA batches, and the CAS is 2381089-83-2 if you're checking cross-references—we usually have stock in 5mg, 10mg, 15mg, and 30mg per vial, though confirm lead time if you need the 30mg quickly.
You keep it at 0-4°C short term, -20°C for anything beyond two weeks, and shelf life is over two years if you don't freeze-thaw it repeatedly; one thing that trips people up is the powder absorption—it's hygroscopic, so open it in a dry atmosphere unless you want degraded assays.
Actually, this isn't for in vivo GLP-1 dominant models where you need slow clearance—its half-life is longer than semaglutide, about 5-6 days in rodents, so dose timing matters more than you'd think; most buyers go with the 10mg vial for pilot studies (we recommend pulling three aliquots per vial).
Molecular weight is C223H343F3N46O70, about 4.9 kDa, and teh 30mg packaging is better suited for chronic dosing—the smaller vials give you less waste per run anyway, but if you're running high-throughput, the 15mg per vial cuts reconstitution steps pretty much in half.
6, we supply pharmaceutical grade, not reagent grade, so tolerance on peptide content is tighter than what you'd get form standard synthesis houses; don't expect this to work as a standdard for formulated drug product testing, though—it's for research only, no clinical use, and the COA comes with each box.
