FAQ
Is RT3 approved for human use?

No. RT3 is supplied strictly for laboratory research and is not approved for human or veterinary administration.

Read: What is RT3?
What receptors does RT3 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 RT3?
How should RT3 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 RT3?
Why is RT3 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.
