Retatrutide in Ireland

Short answer

Retatrutide - shortened to reta in most searches - is an investigational triple agonist acting at the GLP-1, GIP and glucagon receptors. It is supplied to researchers as a lyophilised powder in a sealed vial, holds no marketing authorisation in Ireland or anywhere in the EU, and is sold strictly as a laboratory reagent.

Why is it always written as reta?

Purely convention. Search behaviour in Ireland has settled on the short form, the same way tirzepatide became tirz. Both refer to the same compound. If you arrived here searching for reta, this is the page you wanted.

How does price per milligram work?

Retatrutide is listed in several vial sizes, and comparing headline prices between suppliers is close to meaningless without normalising to price per milligram. A larger vial almost always carries a lower per-milligram figure, which is why a cheaper-looking small vial is often the more expensive purchase.

Current sizes and live pricing are on the Retatrutide product page, where the per-milligram figure is shown alongside each size rather than left for you to calculate. Availability is confirmed on the fulfilling partner's page before checkout, because stock moves faster than any static page.

Where does Retatrutide stand legally in Ireland?

It is an unapproved investigational compound. The Health Products Regulatory Authority (HPRA) authorises medicines in Ireland, and Retatrutide is not on that register - no marketing authorisation has been granted anywhere in the EU. It is therefore handled as a research chemical, not as a treatment, and nothing on this site describes a human use for it.

This matters more for Retatrutide than for most compounds, because it belongs to a drug class that does have licensed members. The existence of approved GLP-1 medicines does not extend any approval to Retatrutide. The legal information page sets out the distinction.

What does the certificate show?

Purity is determined by HPLC and published per batch, with the batch number and testing date printed on the document. Every certificate published here meets a minimum of 99% - a batch that does not is withheld rather than published with a caveat. You can open the current one on the lab reports page before ordering.

Delivery to Ireland

Orders are fulfilled from inside the EU, so a shipment to Ireland moves within the single market. There is no customs entry, no VAT charged at the border and no handling fee on arrival - the situation that trips up orders placed outside Europe, which is what most searches about importing peptides to Ireland are running into.

What is it studied for?

Published work on Retatrutide concerns receptor pharmacology across the three targets and metabolic signalling in preclinical and clinical research models. It is referenced here as research context only. No outcome is claimed, and the compound is not offered for human or veterinary use.
