So you're looking into retatrutide for your lab work—makes sense, a lot of researchers have been circling this one lately, especially for metabolic studies, and we've been moving it for a few years now, so we've seen the questions pile up.

99% is what we quote on purity, and every batch gets an HPLC run to confirm that, though we usually have COAs on hand, but confirm lead time if you're in a hurry, because the 5mg vial is actually the most popular for initial, while teh 15mg is better for longer-term protocols since you reconstitute less often.

it come as a freeze-dried powder in individual glass vials, with ten vials to a box, and room temperture storage is fine—just keep it dry and out of direct light, and the shelf life is three years form the date of manufacutre (check the lot number, it varies by batch).
Most buyers go with the 10mg vial to split into multiple doses, but if you're running chronic studies, the 30mg or 60mg vials save on reconstitution steps, basically fewer vials to handle overall.

Now, one thing to keep in mind—this is strictly for research and is not suited for any in vivo human use, because the formulation isn't sterile enough for that, and we don't test for endotoxins, so it's really just for bench work, not clinical.

For ordering, we require a minimum of one kit, which is that ten-vial box, and if you want custom labeling on vials for bulk orders, you'll need to request that before we ship, as it takes about two to three weeks for the print run.
