We’ve been shippng this retatrutide for a while now, and the 99% purity is what most buyers come back for—it’s not just a number on a sheet, it means fewer impurities messing with your in vivo.

You’ll get it as a lyophilized powder in 5mg or 10mg vials, and we pack ten, so you’re not stuck reordering after a single run—usually takes about 20 days or so form order to your door.

What it does is target metabolic pathways for weight loss research, and the shelf life is two years if you store it right—lyophilized stuff holds up better than reconstituted, which is a detail some folks overlook until they’ve got a batch going bad.


Actually, the 10mg per vial is what most researchers go with for longer studies, but if you’re just screening, teh 5mg works fine—just check the MOQ is one box, so you’re buying ten vials either way.

One thing we’ve learned handling this is that it’s not suited for anything but research use—don’t try to use it in any clinical or human appliction, COA and HPLC data are there for your lab’s records, not for dosing people.

Anyway, we usually have stock, but lead times can shift during Chinese holidays, so it’s worth confirming before you place a big order—the transport package options go up to 30mg per vial if you need a different concentration.
Yes, every batch comes with a third-party lab-tested Certificate of Analysis confirming 99% purity. We can send you the CoA before you order.
For a single box, we usually ship within 24-48 hours after payment clears. Stock is ready to go.
Custom vial sizes are possible but require a larger MOQ than 1 box. For standard sizes, 1 box is fine.
Keep the powder sealed, away from moisture and light, and store it in a freezer at -20°C. It stays stable for the full 2-year shelf life.
We supply a packing list, invoice, and the CoA. If your lab needs a specific letter for customs, just let us know and we can arrange it.
