ION-3R Peptide

Buy ION-3R Peptide

Looking to buy ION-3R peptide for laboratory research? Ion Peptides Solution provides ION-3R as a research-grade peptide intended for qualified researchers and controlled laboratory applications.

ION-3R is a vendor designation associated with retatrutide, an investigational triple hormone receptor agonist that activates the GIP, GLP-1, and glucagon receptors. Retatrutide is currently being studied in clinical research involving obesity, type 2 diabetes, and other metabolic conditions.

ION-3R is supplied as a research-use-only material and is not intended for human or veterinary consumption.

What Is ION-3R Peptide?

ION-3R peptide is a research designation associated with retatrutide (LY3437943). Retatrutide is a single peptide molecule designed to activate three hormone receptors: GIP, GLP-1, and glucagon. This triple-agonist activity distinguishes retatrutide from single- and dual-receptor agonists.

Retatrutide is being investigated in Phase 3 clinical trials across several areas, including obesity, type 2 diabetes, knee osteoarthritis pain, obstructive sleep apnea, cardiovascular and renal outcomes, and metabolic dysfunction-associated steatotic liver disease.

As of September 2026, retatrutide remains investigational and is not FDA-approved. Lilly states that it is legally available only to participants in its clinical trials.

Uses & Potential Research Benefits

Research Uses

ION-3R/retatrutide is being investigated in research involving:

Triple receptor agonism
GIP receptor activity
GLP-1 receptor activity
Glucagon receptor activity
Metabolic research
Obesity research
Glucose and glycemic-control research
Cardiometabolic research
Liver-metabolism research
Body-weight and energy-balance research

Clinical research has reported substantial changes in body weight and glycemic measures in studied populations, but these findings relate to controlled clinical trials of investigational retatrutide and should not be interpreted as established benefits of an unapproved research product.

FAQs

What is ION-3R peptide?

ION-3R is a vendor designation associated with retatrutide, an investigational peptide that activates GIP, GLP-1, and glucagon receptors.

Is ION-3R the same as retatrutide?

Current product and analytical records associate ION-3R with retatrutide (LY3437943). Product identity should nevertheless be confirmed using the specific product label and lot-specific analytical documentation.

What is retatrutide?

Retatrutide is an investigational once-weekly triple hormone receptor agonist that activates GIP, GLP-1, and glucagon receptors.

What is ION-3R used for?

ION-3R is supplied for laboratory research involving triple receptor agonism and related metabolic pathways. Research involving retatrutide is also investigating obesity, type 2 diabetes, and several cardiometabolic conditions.

Can I buy ION-3R peptide?

ION-3R may be offered as a research material for qualified laboratory use. Anyone purchasing research material should ensure that its acquisition and use comply with applicable laws and institutional requirements.

Is ION-3R approved for human use?

No. Retatrutide remains investigational and is not currently FDA-approved.

Does ION-3R have weight-loss benefits?

Clinical trials of investigational retatrutide have reported substantial weight loss in studied populations. However, these clinical findings should not be presented as an established benefit of an unapproved ION-3R research product.

How should ION-3R be stored?

The current product listing specifies −20°C for lyophilized material and −80°C after reconstitution, subject to confirmation from the product’s specific documentation.

Research use only. Not for human or veterinary consumption.

Uses & Benefits

Potential Research Benefits

Researchers may use ION-3R to investigate:

Interactions between GIP, GLP-1, and glucagon receptor pathways.
The biological effects of triple receptor activation.
Metabolic signaling and energy-balance mechanisms.
Glucose regulation in experimental models.
The relationship between triple agonism and body-weight regulation.
Potential applications of multi-receptor agonism in cardiometabolic research.

Dosage

There is no approved human dosage for ION-3R as a research product. Retatrutide is an investigational medication, and clinical-trial dosing should not be converted into instructions for using a commercially sold research product.

Researchers should determine experimental concentrations and procedures according to their validated laboratory protocols, study design, institutional requirements, and applicable regulations.

ION-3R should not be self-administered or represented as a treatment, supplement, or approved medication.

Safety Advice

ION-3R/retatrutide is an investigational compound. Retatrutide has not been approved by the FDA, and Lilly specifically warns against using products claiming to contain retatrutide outside its clinical trials.

Researchers handling ION-3R should follow appropriate laboratory safety procedures and review the applicable Safety Data Sheet and product documentation before use.

Before using research material, verify:

Product identity
Lot number
Purity
Certificate of Analysis
Storage requirements
Laboratory handling procedures
Applicable institutional requirements

For research use only. Not for human or veterinary consumption.

Storage Instructions

ION-3R is supplied as a lyophilized research material. The product listing specifies storage at −20°C for the lyophilized material and −80°C after reconstitution. Laboratories should confirm the storage requirements on the documentation supplied with their specific lot.

General handling practices include:

Keep the container tightly sealed.
Protect the material from unnecessary exposure to moisture and light.
Minimize repeated temperature fluctuations.
Maintain appropriate laboratory inventory records.
Follow lot-specific storage instructions.
Use validated laboratory procedures for any experimental preparation.
