So you've got a lab running metabolic pathway studies and principal investigator just flagged retatrutide as needing bulk white powder for the next quarter — we actually keep a decent stock of the 5mg and 10mg vials ready to go, and we usually have 50 units or so on hand for immediate dispatch, though teh lead time can stretch to 20 days or so if you're ordering over 500 vials.

The CAS is 121062-08-6 with a molecular weight of 1024.18 g/mol by the way, and what it does is hold >99% purity by HPLC which matters because impurities can throw off in sensitive assays — it's soluble in water so you don't need weird solvents, and we store it at -20°C in dry, dark conditions, and the shelf life runs two years when you follow that (we've seen labs push it to three but don't recommend it).
Most buyers go with the 10mg vial for metabolic work, but honestly the 5mg is better if you're running pilot batches or testing multiple compounds side by side — just keep in mind this stuff is not suited for anything with live human cells or in vivo applicaion past basic receptor binding, so don't expect it to work for cytotoxicity screening or anything like that, and the powder can clump a bit if you open the vial in high humidity (a detail that's bitten a few customers who didn't read the storage notes).

Anyway, each batch ships with a full COA and HPLC trace, and we handle payment via wire or credit card with a 2-3 day window for confirmation — roughly 85% of orders clear within 48 hours.
We typically require a minimum order of 10 vials per batch, but we can discuss smaller orders for initial testing.
Lead time is usually 5-7 business days after order confirmation, depending on your location and customs clearance.
Yes, we include a COA with each batch, detailing the HPLC purity and other quality specs like appearance and solubility.
Keep the vials at -20°C in a dry, dark place—avoid freeze-thaw cycles and direct light to preserve stability.
We can discuss bulk packaging options for larger quantities, but standard vials ensure stable storage for research use.
