Buy Semaglutide Tirzepatide Powder 99% Purity for Pharmaceutical Use

We've been running these peptides through HPLC and mass spec before they leave, and the 99% purity holds consistently — we usually have stock, but confirm lead time if you need more than 50 vials at once.

For researchers looking at dual GIP/GLP-1 receptor agonism, this is the one that's been showing up in most of the phase 3 weight loss trials, though it's not suited for anything beyond lab use — we mark everything 'for research only' and the COA reflects that.

The molecular weight comes in at 4813 g/mol, which is pretty much what you'd expect for a synthetic peptide analog with that PEG-modified lysine side chain, and the CAS is 2023788-19-2 if you're cross-referencing with your internal database.

Each vial comes as a (2mg, 5mg, or 10mg depending on your batch preference), and what it does is reconstitute cleanly in sterile water or buffer — the 10mg vials are easier to handle in most cases if you're running.

Storage is straightforward at 2-8°C after opening, but honestly the powder stays stable at room temp for a few weeks if you're not opening it — we include a retest policy within 30 days if teh HPLC shows anything off, but that rarely happens.

We ship in cardboard cartons with individual vials, and the EC number is 200-001-8 — anyway, the batch consistency has been tighter than most suppilers we've tested against, so we're comfortable with quailty assurance side.
