01

What it is

Inside is retatrutide, a peptide built of 39 amino acids, the same building blocks that every protein in your body and your food is made from. In other words, it's a concentrated set of the individual parts of a protein.

02

How you use it

It comes as a pre-filled, ready-to-use pen. One click, once a week. One pen = up to 8 weekly doses = 2 months.

03

The result

Less hunger, steady fat loss. Up to 24% body weight.


P.S. Physical activity can slightly speed up the process and strengthen your final results.

Ordering retatrutide from Ireland

Most listings you will find are vials of lyophilised powder that you reconstitute yourself. NEXA ships a filled pen instead: the concentration is stated on the pack and the dose steps are fixed, so there is nothing to calculate.

The peptide appears as retatrutide and as reta - the development name is LY3437943. All three refer to the same triple GLP-1 / GIP / glucagon receptor agonist.

Made and lab-tested in Germany. Every pack includes a printed usage protocol; the 40mg and 80mg packs add the smoothie and shake book plus an AI dosing reminder. Support is available at support@synedica-reta.com before and after ordering.

If you want to sanity-check a dose from a powder vial, use the peptide calculator.
