Tirz (Tirzepatide): What It Is, Research Use, Storage and Single Vials

Tirz is shorthand for tirzepatide, a synthetic peptide that acts on two gut-hormone receptors, GIP and GLP-1. In medicine it is the active ingredient in the prescription pens sold as Mounjaro and Zepbound. Our vials are not those pens. They are lyophilized (freeze-dried) research powder.

Why researchers look at it

Tirzepatide is one of the most published peptides of the last few years, so researchers often want it as a reference compound alongside newer molecules like Reta.

Sizes

We carry Tirz in 5mg, 10mg, 15mg, 20mg, 30mg, 40mg, 60mg and 120mg vials. See every size on the Tirz page.

Storing Tirz vials

Freeze-dried tirzepatide is stable in transit. When it arrives, keep the sealed vial in a refrigerator, dark and dry. After reconstitution, it goes back in the fridge. Our storage guide walks through it.

Picking Tirz sizes

Eight Tirz sizes run from 5mg to 120mg, and each vial is priced on its own. Try a small size, compare per-mg prices on larger ones, or buy several. Single Vial Peptides ships each US order free, international orders for a flat $40, and adds a free 3ml bac water if you tick the box.

Not Mounjaro or Zepbound

Tirz from this shop is research powder for laboratory use. It is not for people or animals, and nothing here is dosing or medical advice.
