Retlira 30 — Retatrutide 30 mg Pre-Filled Pen

Triple-Receptor Research | Metabolic Health | Weight-Management Research

Product Overview

Retlira 30 is a pre-filled pen-format research product listed as containing 30 mg of retatrutide in a 3 ml presentation.

Retatrutide, also known as LY3437943, is an investigational peptide being studied for its activity across three metabolic hormone receptors: GLP-1, GIP and glucagon. These pathways are involved in appetite signalling, glucose regulation and energy metabolism.

Its triple-receptor mechanism has attracted significant scientific interest because researchers are investigating whether coordinated activity across these pathways can influence body-weight regulation and other metabolic outcomes.

Key Clinical Research Findings

1. Significant Body-Weight Reduction

A Phase 2 clinical trial published in The New England Journal of Medicine in 2023 evaluated retatrutide in 338 adults with obesity or overweight and a weight-related complication, excluding diabetes.

After 48 weeks, average body-weight reductions were:

  • 1 mg trial group: 8.7%

  • 4 mg trial group: 17.1%

  • 8 mg trial group: 22.8%

  • 12 mg trial group: 24.2%

The placebo group experienced an average reduction of 2.1%.

These results demonstrated substantial weight reduction in the studied population. They reflect a specific clinical trial and do not predict results from Retlira 30.

2. Triple-Receptor Activity

Retatrutide's defining research feature is its activity across GLP-1, GIP and glucagon receptors. Researchers are investigating how these pathways interact in the regulation of appetite, energy intake and energy expenditure.

This mechanism distinguishes retatrutide from compounds that target only GLP-1 or both GLP-1 and GIP receptors.

3. Waist Circumference and Body-Composition Research

In the Phase 2 trial, average waist-circumference reductions ranged from approximately 6.5 cm to 19.6 cm across the retatrutide groups, compared with 2.6 cm in the placebo group.

These findings provide additional evidence of changes in body measurements during the study. They should not be interpreted as guaranteed outcomes or as proof of specific changes in muscle mass or body composition.

4. Metabolic Health Research

Researchers are investigating retatrutide's potential effects on glucose regulation and other cardiometabolic markers. Its multi-receptor activity makes it an important subject of ongoing metabolic research.

However, the evidence remains under development, and further clinical trials are needed to establish its safety, long-term effects and potential clinical applications.

FAQ's & Tips

What is RETLIRA 30?

RETLIRA 30 is a pre-filled research pen listed as containing 30 mg of retatrutide (LY3437943) in 3 ml of solution. It is supplied for laboratory and scientific research purposes only, not for human or animal consumption.

What does 30 mg / 3 ml mean?

The listed 30 mg is the total amount of compound in the pen, and 3 ml is the total solution volume. These are product specifications, not a recommended dose or administration instruction.

What is retatrutide being researched for?

Retatrutide is an investigational compound studied for activity at GLP-1, GIP and glucagon receptors. Research examines how these pathways relate to metabolic signalling, glucose regulation, energy metabolism and body-weight outcomes. Compound-level research does not establish the safety or effectiveness of this finished product.

Does this product require reconstitution?

The product is listed as a pre-filled 3 ml solution rather than a powder requiring reconstitution. Researchers should follow the supplier's product-specific documentation and their institution's laboratory procedures for handling.

What is included in the pack?

The listed pack contents are one pre-filled RETLIRA 30 research pen with disposable needle tips. The number of tips is not specified in the product information.

Is RETLIRA 30 intended for personal weight management?

No. This listing is for research use only and does not present RETLIRA 30 as a medicine or treatment. It is not intended for self-administration or human or animal consumption. Consult a qualified healthcare professional about personal weight-management treatment.

Do published trial results guarantee results from this pen?

No. Published studies concern investigational retatrutide under specific clinical-trial conditions. They do not verify the identity, purity, safety or effectiveness of RETLIRA 30 and should not be interpreted as promised outcomes from this product.

How should the product be stored and handled?

Follow the storage conditions, expiry information and handling instructions on the product label and supplier documentation. If these are missing or unclear, contact Health-Tech for product-specific guidance before research use; do not assume conditions from another peptide product.

1. Published Phase 2 Trial: Retatrutide for Obesity

Jastreboff AM, et al. Triple–Hormone-Receptor Agonist Retatrutide for Obesity — A Phase 2 Trial. New England Journal of Medicine. 2023;389:514–526. DOI: 10.1056/NEJMoa2301972.

This randomized, double-blind, placebo-controlled trial evaluated retatrutide in 338 adults with obesity, or overweight with a weight-related condition, without diabetes. It examined changes in body weight and safety outcomes over 48 weeks.

The study reported substantial average body-weight reductions in retatrutide groups compared with placebo. Gastrointestinal adverse events were common, and dose-dependent increases in heart rate were also reported. The full paper should be consulted for the study design, numerical results, adverse events and limitations.
