Trying to find retatrutide that actually hits 99%+ by HPLC without paperwork being a headache — we've been there too, so what we do is run every batch through a COA and keep it on file.
CAS 2381089-83-2, that's soluble in water at 5mg/ml, and we stock it in 5mg, 10mg, 15mg, or 20mg vials depending on what your protocol needs — the 10mg is what most buyers go with, honestly.

Stored at -20°C it holds for two years, but we've seen it stay stable a bit longer if you keep the desiccant in and don't open it until you're ready — basically, treat it like any other GLP-1 analogue and you're fine.
It's not meant for anything beyond research use (that's teh whole point), and the techncial grade means you're getting a tighter tolerance on purity than some of the cheaper stuff floating around, though we usually have stock and can ship within 20 days or so.
our company can do custom labeling or bulk packging if you're ordering more than a few hundred vials — just confirm the MOQ when you reach out, since lead time varies (usually 2-4 weeks).
We don't have a fixed MOQ listed on the spec sheet, but for wholesale batches we typically start at gram-level quantities. Just reach out with your target volume, and we'll confirm what's doable.
Lead time depends on the quantity and any custom specs. For standard 5mg to 20mg vials, we can ship within 5-7 business days after order confirmation. Larger or customized batches may take 2-3 weeks.
Yes, every batch comes with a COA showing the 99%+ HPLC purity and other specs like appearance and water solubility. It's included with the shipment as standard.
Store it at -20°C in a freezer, away from light and moisture. Keep the vial sealed until use. Proper storage ensures it stays stable for the full 2-year shelf life.
Sure, we offer customized packaging for bulk orders. You can choose your own vial size within the 5mg to 20mg range, or add a private label. Just let us know the details when you place the order.
