So you've been looking at retatrutide form other suppilers and wondering if the purity claims actually hold up—we've been in this space long enough to know the difference between a COA that looks good and one that actually reflects real batch testing.

The CAS number is 1401708-83-5, and we're running it at ≥98% purity by HPLC, which matters for dose consistency because even small impurities can throw off your results in longer studies.

Most buyers go with the 10mg or 20mg vials for initial work, but we've got everything from 5mg up to 60mg (usually in stock for the smaller sizes) if you need to scale up without switching suppliers—teh 60mg is better than running multiple vials if you're doing chronic dosing.
It's a white powder, and what it does is hold up well under standard storage conditions—cool, dry place, and you'll get the full 24-month shelf life if you keep the desiccant in there.

Basically, what you get when ordering is a batch-specific COA via email, TDS and SDS on request, and packaing that's actually sealed tight enough for internatioanl shipping without worrying about moisture damage.

One thing we don't push it for is any kind of human use—strictly research only, and we'll flag that on invoice so there's no confusion with customs or your compliance team.
