We've got the >99.9% HPLC purity you're after on the semaglutide — CAS 303760-60-3 — and it's a white to off-white powder, pretty much standdard for this GLP-1 analog.
It's soluble in water at pH 7.0-8.0, so you'll want to check that before reconstitution, and the molecular weight sits at 4113.6 g/mol, which matters for your dosing calculations.
Storage is straightforward: keep it at 2-8°C short term, but for long haul — 24 months stability when properly stored — you'll need -20°C, and we usually have stock but confirm lead time for larger orders.
Most buyers go with the 10 format, but custom options are available if you need them; it's not suited for anything beyond research applicaion, of course.
Also, teh 5mg or 10mg vials are typical for UK supply, and we've found the shorter handling time at room temperature is a detail buyers appreciate but rarely ask about upfront.
20 days or so for dilevery on standard quantities, and we include COA with HPLC data as standard — just let us know the batch size you're targeting.
