View & buy on store →About Retatrutide
Retatrutide (development code LY3437943) is a synthetic triple-agonist peptide that acts on three metabolic receptor targets at once: the glucagon-like peptide-1 (GLP-1) receptor, the glucose-dependent insulinotropic polypeptide (GIP) receptor, and the glucagon receptor. This 30 mg presentation is the largest we offer, intended for extended laboratory study protocols.
Within the research community, Retatrutide has drawn substantial interest as a subject for studying metabolic regulation, energy homeostasis, insulin signalling, and adipose-tissue metabolism in pre-clinical and laboratory models. It is supplied by Vital Research Labs strictly as a reference compound for in-vitro laboratory investigation.
Receptor targets
- GLP-1 receptor — a target widely studied in incretin and glucose-regulation research.
- GIP receptor — an incretin receptor investigated alongside GLP-1 in metabolic-pathway studies.
- Glucagon receptor — a target studied in relation to energy expenditure and hepatic metabolism.

Reconstitution & handling
Retatrutide is supplied as a lyophilised (freeze-dried) powder. For research handling it is typically reconstituted with bacteriostatic water; the exact volume depends on the concentration a given research protocol calls for. Our reconstitution calculator can be used to work out volumes for a target research concentration. Handle under appropriate laboratory conditions and avoid repeated freeze–thaw cycles of the reconstituted solution.
Storage & stability
- Lyophilised powder — store at -20 °C, protected from light and moisture.
- Reconstituted solution — store at 2–8 °C and use within 28 days.
- Handling — minimise freeze–thaw cycles; keep vials sealed until use.
Quality & testing
Every batch supplied by Vital Research Labs is analysed by an independent third-party laboratory. Purity is confirmed by high-performance liquid chromatography (HPLC) and identity by mass spectrometry (MS). The Certificate of Analysis for this batch is published in our CoA library once received.
Shipping within Australia
Retatrutide is dispatched from within Australia to Australian research customers, packaged discreetly and appropriately for a lyophilised research compound. Orders are processed on receipt of payment via bank transfer.
Frequently asked questions
Is Retatrutide available in Australia for research?
Yes. Vital Research Labs supplies research-grade Retatrutide (40mg) to Australian research customers, dispatched domestically. It is provided strictly for in-vitro laboratory research and is not for human or veterinary use.
What purity is your Retatrutide?
This batch is verified at 99.850% purity by third-party analytical testing (HPLC for purity, mass spectrometry for identity). The Certificate of Analysis for batch CS-re30200 is published in our CoA library.
How is Retatrutide tested?
Each batch is analysed by an independent third-party laboratory using HPLC to confirm purity and mass spectrometry to confirm identity. Batch-specific values are recorded on the Certificate of Analysis once testing is complete.
How should Retatrutide be stored?
The lyophilised powder is stored at -20 degrees C, protected from light and moisture. Once reconstituted for research it is kept at 2-8 degrees C and typically used within 28 days.
What is the difference between the 10mg, 20mg, 30mg and 40mg vials?
The compound is identical; only the quantity of lyophilised powder per vial differs. The 30mg presentation is intended for extended research protocols requiring more material, and offers a lower cost per milligram than the smaller presentations.
Is Retatrutide intended for human use?
No. Retatrutide (40mg) supplied by Vital Research Labs is intended strictly for in-vitro laboratory research and development. It is not a medicine or therapeutic good and is not for human consumption, veterinary use, or clinical application.
