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 combined single-molecule activity distinguishes it from earlier single- and dual-agonist research peptides.
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
In research contexts, Retatrutide is characterised by its simultaneous activity across three receptors involved in metabolic signalling:
- 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, the powder is typically reconstituted with bacteriostatic water; the exact volume depends on the concentration a given research protocol calls for. 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). This batch is verified at 99.49% purity, and a Certificate of Analysis is available for the batch so researchers can verify exactly what they are working with.
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.
