Reta (Retatrutide): What It Is, Research Use, Storage and Single Vials

Reta is shorthand for retatrutide, an investigational peptide that acts on three receptors: GIP, GLP-1 and glucagon. It is still in clinical trials and is not an approved drug anywhere. There is no brand-name version you can get from a pharmacy.

Why researchers look at it

Because it hits three targets instead of one or two, Reta gets compared with Tirz and Sema a lot in the research literature. Read why retatrutide is still not approved for the public record.

Sizes

We carry Reta in 5mg, 10mg, 15mg, 20mg, 30mg, 40mg and 60mg vials. See them all on the Reta page.

Storing retatrutide powder

Retatrutide is shipped freeze-dried so it travels without ice. Put the sealed vial in the fridge, keep it dark, and once it is mixed with bac water, keep it refrigerated. Our storage guide has the full checklist.

Choosing a Reta size

With seven sizes from 5mg to 60mg, each Reta vial is bought on its own, so you can pick one size, mix sizes, or order several of the same. Single Vial Peptides ships every US order free, charges $40 flat worldwide, and offers a free 3ml bac water by checkbox.

An unapproved molecule

Retatrutide is still investigational. Reta on this shop is research material only: not for human or animal use, with no dosing or medical guidance.
