So you're looking at retatrutide — we've been supplying this triple agonist since it hit the research scene and teh 99% purity we hold is consistent batch to batch, which matters when you're running dose-response work on GCGR, GIPR, and GLP-1R pathways, and we usually have the 10mg or 15mg vials in stock but confirm lead time if you need 20mg vials.
We do the lyophilized powder format, which stores well for two years under refrigeration if kept dry and away form light, and most buyers go with the 10-vial box to get a decent MOQ without overcommitting on storage space, though 20mg vials are actually easier to handle for larger studies.
But here's thing — this isn't for anything beyond in vitro or in vivo research because the triple agonist profile can hit hard on weight reduction in models, and we've seen okay-quailty materail floating around that degrades fast, but ours holds tighter tolerance than some generic batches we've tested, basically stable at -20°C for months if you're careful about moisture.
For procurement types, we issue a full COA with HPLC data and a TDS on request — payment is typically bank transfer or cryptocurrency for routine orders (roughly 30% deposit for first-time buyers) and shiping is via discreet courier with tracking, about 10-14 days or so to the UK depending on customs, and we've had no issues with Royal Mail or DHL on that route.
We don't have the exact CAS number on hand every time someone asks for it (2381089-83-2 if you need it), and the 0.0643 nM GIPR EC50 kicks in pretty quickly in target engagement assays, but honestly many labs skip those finer specs and just go by the weight curves — we've done a fair bit of work with academic groups in Cambridge and they usually stick with 10mg vials for pilot studies.
One mild limitation worth noting: this retatrutide isn't the best choice for chronic dosing studies without careful plasma stability checks because its lyophilized form reconstitutes fine in saline but loses potency over a week at 4°C, so plan your reconstitution volume accordingly — our company can share the typical protocol we've had good results with.
We can do as little as 1 box — that's 10 vials. MOQ is flexible, but for custom packaging or bulk orders, just reach out and we can adjust.
Yes, we provide a COA with every batch. It shows the HPLC purity results, so you can verify the 99% claim yourself.
Standard delivery to the UK takes about 5-8 business days after payment clears. Express options are available if you need it sooner.
We currently stock 10mg, 15mg, and 20mg per vial. Custom sizes are possible for larger orders — just ask us directly.
Keep it refrigerated, dry, and away from light. Stored correctly, it stays stable for 2 years from the production date.
