Factory Supply Tirzepatide Peptide - Buy Semaglutide Online UK with 99% Purity

You reconstitute the lyophilized powder in buffer, and it's ready for whatever assay or study you're running—basically, it behaves like you'd expect from a 99% pure GIP/GLP-1 receptor agonist, but we've seen customers use it for binding studies more than anything else.

CAS is 2023788-19-2, molecular weight sits at 4813 g/mol, and purity is held above 99% by HPLC—we do a COA, and the EC number is 200-001-8 if your import paperwork needs it; storage is short-term at 0–4°C or long-term at -20°C, and shelf life is over 2 years if you keep it sealed and dry.

It's not ideal for oral dosing studies in vivo unless you've got a dilevery system worked out, since it's a peptide and gets degraded in gut—most buyers use it for in vitro work or as a reference standdard; frankly, the 5mg vial is easier to handle for small runs, though 30mg gives more yield per reconstitution.

5mg, 10mg, 15mg, and 30mg per vial, and we usually have stock for UK, US, and EU orders (confirm lead time though, sometimes it's 2 weeks or so). We handle import docs for UK researchers, but you'll want to double-check your local customs regs for peptides—we ship dry ice for frozen stuff, but teh powder itself is stable enough for ambient transit within 3 days.

A detail most don't ask about but matters: the vial stoppers are butyl rubber with a PTFE face, so no silicone oil contamination issues in your samples—and we'll send an SDS just in case your lab requires it for compliance.
