1 / 3Retatrutide
40 mg · pre-filled · sealed
Most metabolic peptides knock on one door, and the research plateaus. Retatrutide knocks on three — GLP-1, GIP and glucagon — the most complete receptor profile in the class.

What it is
A triple-receptor peptide studied at GLP-1, GIP and glucagon — the most complete receptor profile in the class.
It hits three receptors at once — GLP-1, GIP and glucagon — so appetite, blood-sugar response and energy metabolism move together instead of one at a time. One pen covers the full titration schedule.
Supports
- Appetite regulation and portion control
- Steady energy rather than peaks and crashes
The appetite pathway. Studied for how the gut–brain pathways dial hunger and fullness up or down.
The glucose pathway. Investigated for how readily cells take up insulin and manage glucose.
The glucagon arm. The glucagon arm is researched for how the body taps stored fat for energy.

Before you order
What is Retatrutide?
Retatrutide is a synthetic triple-receptor peptide (GLP-1, GIP and glucagon), supplied as a pre-filled research pen for controlled analytical and in-vitro experimentation. It is intended strictly for in-vitro laboratory research use only.
What is it studied for in research?
In preclinical and cell-based laboratory research it is examined for incretin-pathway signalling across three receptors — appetite regulation, glucose handling and energy metabolism. These are laboratory research observations only and are not established human or veterinary effects.
Is it legal to buy in the UK?
Retatrutide is legal to buy and possess in the UK for laboratory research purposes. It is not a licensed medicine and cannot be sold for human or veterinary consumption — every pen is labelled for in-vitro research use only, and the purchaser is responsible for handling and storage under applicable regulations.
What purity is it, and is it lab-tested?
This batch was tested independently by Janoshik: batch R40-20260203, 98.86% purity, 17.90 mg/ml. Verify it yourself at janoshik.com with key 5FQ3GCAL5KAQ. Manufactured in Switzerland, held and dispatched from the UK.
Do you send the test results?
Yes — the Janoshik report is summarised above with its verify key, and the full report is available on live chat or by email at [email protected], before you order if you like.
How is it supplied?
As a pre-filled multi-dose research pen (40 mg total), with single-use needles. Ready out of the box, no reconstitution.

My pen arrived warm — is it ruined? Transit temperature for a pre-filled pen
The most-asked question in every peptide forum, answered for the wrong product. Powder shrugs off a warm afternoon; a solution degrades slowly and predictably. What the stability data say, and what to do with yours.

ReadIs this Janoshik report real? The fraud patterns, and a five-minute check
Buyers keep finding the same Janoshik report on three different vendors' sites, to the decimal. It is not a coincidence. The four ways a report gets faked, the one way it gets borrowed, and a five-minute routine that catches all of them.

ReadBatch traceability: how you know the pen in your hand is the one that was tested
The sharpest objection in any peptide thread: they could test one unit and ship you anything. True. The answer is a chain — batch, carton, certificate, report — and knowing which links a vendor cannot forge.
