Frequently asked questions.
Is retatrutide approved for human use?
No. Retatrutide is supplied strictly for laboratory research and is not approved for human or veterinary administration.
Read: What is Retatrutide? →What receptors does retatrutide act on?
In published research it has been characterised as a triple agonist acting on the GLP-1, GIP and glucagon receptors.
Read: What is Retatrutide? →How should retatrutide be stored?
Lyophilised vials are stored at 2–8°C, protected from light. Once reconstituted with bacteriostatic water, store refrigerated and use within 30 days.
Read: What is Retatrutide? →Why is retatrutide of interest to researchers?
Its simultaneous activity at three incretin-related receptors makes it a useful tool compound for probing combined signalling pathways in metabolic research.
