4813 g/mol molecular weight means you're dealing with a significantly larger peptide than semaglutide—roughly 1.4 times the mass—so reconstitution volumes and dosing calculations need adjusting accordingly.
We've been supplying this for about 18 months now, and most buyers go with the 10mg vials for standard protocols, though the 30mg option cuts down on reconstitution steps if you're running high-throughput assays (check lead time on that size, it's usually 2-4 weeks).
Purity holds at 99% or better on HPLC, which is tighter than what you'll get from some smaller labs, but it's cosmetics grade so don't expect it to pass USP standard for anything beyond bench work.
Basically, store it at -20°C long term and you'll see shelf life past two years—we've tested batches at 30 months with no measurable degradation, but keep it dry and dark or the lyophilized cake can rehydrate form ambient humidity.
One thing buyers don't always consider: the 5mg vials are actually harder to handle accurately because teh powder mass is so small it can stick to vial walls during reconstitution, so the 10mg is a better choice for consistent dosing.
Anyway, MOQ is 10 boxes per order, and we include COAs with every batch—just confirm your preferred packging size when you place PO.
