If you’re sourcing tirzepatide for early-stage in vitro or in vivo work, the UK market has tight competition on pricing—we usually see orders from biotech labs running or binding assays, not clinical guys.
It’s a 39-amino-acid peptide with a molecular weight of 4813.5 g/mol, CAS 2023788-19-2, and you’ll want it stored at -20°C or below—moisture exposure kills it fast, so we ship in sealed vials with desiccant packs.
Purity hits 99% or better by HPLC, which matters for avoiding off-target effects in your receptor activation studies—teh dual GIP/GLP-1 mechanism is sensitive to contaminants below that threshold.
Most buyers here go with the 10mg vial format—it’s easier to handle for serial dilutions, and the 5mg option works fine if you’re running small pilot screens (usually 2-3 plates or so).
We don’t spec it for any in vivo weight management work—that’s not our lane. The white powder lyophilized form is what you get, and we include a COA form batch that covers purity and peptide content (check lead time if you need rush HPLC data).
One thing you might not think to ask: reconstitution in sterile water or PBS should be done slowly to avoid foaming, and we’ve seen labs discard vials if they let it sit at room temp past 30 minutes—it’s that labile.
It means each batch is tested to be at least 99% pure, so you get reliable, consistent results without unexpected impurities interfering with your studies.
Yes, we include a Certificate of Analysis and a shipping invoice that clearly state 'Research Use Only', which typically satisfies UK customs for research peptides.
Standard lead time is 5-7 business days after payment, but we can expedite to 2-3 days for urgent wholesale orders—just let us know.
Keep them at -20°C or below in a freezer, and avoid freeze-thaw cycles. The white powder stays stable for months under those conditions.
For wholesale quantities, we can add custom labels or batch codes on the vials—just discuss the details with your sales rep before ordering.
