Description
Retatrutide is a 39-amino-acid research peptide characterised in the literature as a triple receptor agonist, with reported activity at the GLP-1, GIP and glucagon receptors. LiveWell supplies it as a lyophilized vial in 10mg, 15mg, 20mg and 40mg sizes, strictly for in-vitro laboratory research use only.
Chemical information
- Sequence length: 39 amino acids
- Class: Triple GLP-1/GIP/glucagon receptor agonist
- Half-life: ~6 days reported in published literature
- Available sizes: 10mg, 15mg, 20mg, 40mg
Why triple-receptor activity is studied
Retatrutide is examined in comparative research against single- and dual-agonist compounds because of its broader receptor-engagement profile, activating three distinct receptor pathways simultaneously. This is the property most often studied in multi-receptor signalling and metabolic pathway interaction research.
Studied in
- Triple-agonist mechanism research (vs single and dual agonists)
- Receptor-binding and metabolic-pathway studies
- Glucagon-receptor signalling research
- Comparative analysis with dual and single receptor agonist research compounds
Storage & handling
- Store the lyophilized vial refrigerated at 2–8°C, protected from light and heat
- Reconstitute with bacteriostatic water; reconstituted material has a shorter storage window
- Follow your laboratory’s standard peptide handling protocol

Frequently Asked Questions
What is Retatrutide?
Retatrutide is a 39-amino-acid research peptide characterised as a triple receptor agonist, with reported activity at GLP-1, GIP and glucagon receptors. Supplied as a lyophilized vial strictly for laboratory research use only.
How does Retatrutide differ from Tirzepatide?
Retatrutide activates three receptors (GLP-1, GIP, and glucagon). Tirzepatide activates two (GLP-1 and GIP). The additional glucagon-receptor activity is the primary structural distinction studied in comparative research.
What purity is LiveWell Retatrutide, and is a COA included?
Every batch is third-party tested at ≥99% purity by HPLC, with mass spectrometry identity confirmation and LAL endotoxin testing. A full Certificate of Analysis is included.
How should Retatrutide be stored and reconstituted?
Store refrigerated at 2–8°C, protected from light and heat. Reconstitute with bacteriostatic water; reconstituted material has a considerably shorter storage window.
Is Retatrutide a drug or supplement?
No. Retatrutide research peptide is a research compound sold strictly for laboratory use only. It is not FDA approved and is not a drug, dietary supplement, food or cosmetic.
