About Retatrutide

Retatrutide is a synthetic 39-amino-acid peptide engineered as a triple agonist of three metabolic receptors: GLP-1, GIP and glucagon. The molecule incorporates non-natural amino-acid modifications and a C20 fatty-diacid attachment that extends its plasma half-life — a structural strategy shared with semaglutide and tirzepatide. It is one of the most-studied incretin-class compounds in recent metabolic and obesity research.

RetaNord supplies retatrutide as a 10 mg lyophilized powder verified through Veritalys, an EU peptide testing service, at 99%+ identity purity by HPLC, with identity confirmed against a reference standard. Every lot gets a full 7-test panel, including endotoxin and germ testing, and the lot-specific Certificate of Analysis is included with every order.

What it's known for

Retatrutide is best known for weight loss and metabolism. Here is what it is most associated with. (Still investigational; supplied for laboratory research use only.)

Trial endpoint

Body-weight change was the primary endpoint reported in its published Phase-2 trial.

Triple agonist

Hits three receptors — GLP-1, GIP and glucagon — hence 'next generation'.

Metabolism

Associated with blood-sugar and metabolic regulation.

Still in trials

NB: retatrutide is investigational and not an approved medicine.

Ozempic vs Retatrutide

How it works

Retatrutide acts on three metabolic receptors at once — GLP-1, GIP and glucagon (a 'triple agonist'). GLP-1 and GIP reduce appetite and slow stomach emptying; glucagon influences energy expenditure. The combined effect across the three axes is why it is associated with strong weight loss.

What the evidence shows

Retatrutide has completed a Phase-2 trial programme, reported in the New England Journal of Medicine (2023); Phase-3 trials are underway. It is NOT yet an approved medicine — unlike semaglutide (Ozempic/Wegovy) and tirzepatide (Mounjaro), which are already on the market.

Safety data from published trials
Third-party literature — not medical adviceSummarised from published clinical research on the investigational compound. RetaNord products are supplied for laboratory and in vitro research use only; not for human or veterinary use.

In the Phase-2 trial published in the New England Journal of Medicine (2023), the adverse events investigators reported most frequently were gastrointestinal — nausea, vomiting, diarrhoea and constipation — and were described as dose-dependent and generally mild to moderate.

Retatrutide is investigational. It has not been evaluated or approved by the European Medicines Agency, the FDA or any other regulatory authority, and no long-term safety profile has been established.

Documentation & quality

Not just purity: a full panel. Every Retatrutide lot goes through 7 tests at an independent EU laboratory, arranged through Veritalys, and all 7 are printed on one certificate:

A purity number on its own says nothing about how much is in the vial or whether it is clean. The full panel answers all three.

A lot-specific Certificate of Analysis ships with every order. The lot number printed on your vial matches the lot ID on the document, so the material on your bench can always be checked against the data on file.

Retatrutide — questions

Which sizes do you sell?

Single vials of Retatrutide are 10 mg, and you can buy 1 or more: the more vials, the lower the price per vial. For larger amounts, Retatrutide also comes in kits of 10 or 30 vials with 20 mg or 40 mg per vial.

What makes retatrutide unusual?

Retatrutide is a triple agonist — it activates three receptors (GLP-1, GIP and glucagon) in a single molecule. Most incretin-class peptides target one or two of those receptors; the triple-agonist combination is the focus of newer metabolic research.

How is retatrutide supplied?

As a 10 mg lyophilized powder in a sealed vial, with a lot-specific Certificate of Analysis. It should be reconstituted only in an appropriate laboratory setting following your own validated protocol.

Peptide Kits

A separate range of fifteen research peptides — supplied as sealed 10- or 30-vial kits, not per vial like Retatrutide.
