The triple-agonist studied for major weight reduction. GLP-1 / GIP / Glucagon receptor triple agonist peptide, lyophilized for reconstitution.
Lyophilized peptide · single vial
What it is
Retatrutide (LY3437943) is a synthetic single-chain peptide that activates three receptors at once: GLP-1, GIP, and glucagon. It was developed by Eli Lilly and is described in the literature as a triple hormone-receptor agonist. It appears in obesity, type 2 diabetes, and fatty liver research, and has reached randomised Phase 2 trials.

How it works
Retatrutide is a triple receptor agonist studied for major weight reduction in clinical research.
Triple
Three receptors at once
Retatrutide activates GLP-1, GIP and glucagon receptors within a single molecule.
Appetite
Signals through incretins
GLP-1 and GIP activation acts on appetite and insulin pathways, studied for reduced food intake.
Glucagon
Adds energy expenditure
The glucagon component is thought to raise energy expenditure, a third lever beyond appetite alone.
Key benefits
- Weight-management research focused on appetite and body-fat reduction.
- Metabolic protocols looking at blood sugar and energy balance.
- Compared with single- and dual-agonist GLP-1 peptides for stronger effect.
Laboratory research only. Not for human or veterinary use.
What published research is studying
Early human data- Weight reduction in adults with obesity or overweight (Phase 2)
- Glycaemic control and body weight in adults with type 2 diabetes (Phase 2)
- Liver fat in metabolic dysfunction-associated steatotic liver disease (Phase 2a substudy)
- Gastrointestinal tolerability across escalating trial arms
Human evidence is at the Phase 2 stage: randomised and placebo-controlled, but without published Phase 3 or long-term outcome results.
Key research findings and references
Key research findings
In a 36-week Phase 2 trial in 281 adults with type 2 diabetes, HbA1c fell 2.02% at 24 weeks in the 12 mg group, against 0.01% with placebo.
Rosenstock J et al., Lancet 2023In a Phase 2a substudy of 98 participants with liver fat of at least 10%, mean liver fat fell 82.4% at 24 weeks in the 12 mg group.
Sanyal AJ et al., Nat Med 2024Published study duration
- Phase 2 obesity trial: 48 weeks (NCT04881760).
- Phase 2 type 2 diabetes trial: 36 weeks, with the primary glycaemic readout at 24 weeks (NCT04867785).
- Liver fat substudy readout: 24 weeks within the 48-week obesity trial.
Research endpoints
- Percent change in body weight
- Proportion reaching 5%, 10%, or 15% weight reduction
- Change in HbA1c from baseline
- Liver fat content by MRI
- Gastrointestinal adverse events and discontinuation

Research handling
Full handling guide- 01
Lyophilized, sealed, batch-numbered
Each vial ships as a freeze-dried powder under an inert seal, tied to the batch on its Certificate of Analysis.
- 02
Store cold and dark
Unopened vials are kept refrigerated at 2-8°C away from light. Reconstituted material is stored refrigerated and used within the window the research plan defines.
- 03
Reconstitute with bacteriostatic water
The included bacteriostatic water is added slowly down the vial wall and the vial is swirled, never shaken.
- 04
Research use only
Supplied for laboratory research. Not for human or veterinary use. Handle with the personal protective equipment the laboratory requires.
Before you order
What ships in the box?
The vials selected, plus a free supply kit with every vial: one 3 ml bacteriostatic water, ten 0.5 ml syringes and ten alcohol swabs per vial, and the uu.life research handling card.
How does volume pricing work?
The price per vial depends on how many vials of the same strength are on the line. 3-4 vials take 5% off, 5 or more take 10% off. The discount is applied automatically and shows on the product page, in the cart and at checkout.
