Molecular Details
Usage & Storage
Description
Triple receptor agonist (GLP-1 / GIP / glucagon) studied in metabolic, energy-homeostasis, and incretin-signalling research models.
- Triple receptor agonism (GLP-1, GIP, glucagon)
- 39 amino acid peptide with C20 fatty diacid
- Studied across energy-homeostasis pathways
- Investigated in glucose- and lipid-handling models
- Research Grade purity >=98%
Retatrutide (LY3437943) is a single 39 amino acid peptide acting as a triple receptor agonist at the GLP-1 (glucagon-like peptide-1), GIP (glucose-dependent insulinotropic polypeptide), and glucagon receptors. It is built on a GIP peptide backbone carrying non-coded residues at positions 2, 13 and 20, with a C20 fatty diacid conjugated through a gamma-Glu-AEEA linker to extend its half-life. This triagonist design combines incretin-receptor activity with glucagon-receptor signalling. Research has investigated its effects on energy homeostasis, glucose handling, lipid profiles, and hepatic lipid content in preclinical metabolic models. Supplied as a lyophilised white powder. Supplied strictly for in-vitro laboratory research. Not for human or veterinary consumption.
Frequently Asked Questions
Is Retatrutide legal to buy in Australia?
Retatrutide is supplied strictly as a research chemical for in-vitro laboratory use. It is not approved for human therapeutic use in Australia and is not for human or animal consumption. Researchers are responsible for compliance with Therapeutic Goods Administration (TGA) regulations and their institution's protocols.
Is Retatrutide third-party tested?
Yes. Every batch is analysed in-house by HPLC and mass spectrometry. Retatrutide is independently verified by Ozcanium Analytics, an independent Australian laboratory, at 99.39% purity by UPLC-MS/MS, analysed 31 August 2026 on lot APL-RETA5-2608-01, net content 5.54 mg, verification code OZ-HPLCMS-APSL; bacterial endotoxin below 30.0 EU per vial by kinetic chromogenic LAL, analysed 22 August 2026, verification code OZ-ENDOTX-APL1. The reports are published in full on this page, and each verification code can be redeemed in the laboratory's own portal, so the document is confirmed against their records rather than ours.
What purity is Retatrutide?
We specify ≥98% purity — the High-Tier Research Grade (commercial RUO) standard. Every batch is analysed in-house by HPLC and mass spectrometry and ships with a Certificate of Analysis, and Retatrutide is independently verified by Ozcanium Analytics at 99.39% purity by UPLC-MS/MS, analysed 31 August 2026.
Does Retatrutide ship with a Certificate of Analysis (COA)?
Yes — every batch ships with a batch-specific COA documenting HPLC purity and mass-spectrometry identity. 3 Retatrutide batch certificates are published in full at australianpeptidelabs.com.au/certificates/retatrutide, so the analysis can be read before ordering and the batch number printed on the vial matched against it.
Where can I buy Retatrutide in Australia?
Retatrutide can be ordered here from Australian Peptide Labs for in-vitro research use, dispatched same day from within Australia with a COA included.
Do you provide dosing or administration guidance for Retatrutide?
No. As these compounds are supplied for laboratory research only, we do not provide dosing or administration protocols. Our research library covers reconstitution and concentration calculations for in-vitro work.
