Published research context (not product claims)
Retatrutide is described in literature as a triple agonist at GIP, GLP-1 and glucagon receptors. Receptor papers characterise that pharmacology in experimental systems.
Clinical-development publications (including phase-2 work such as Jastreboff et al.) concern investigational drug programmes. They are not authorisation to sell this cartridge as a medicine.
Shop slang “GLP-3” must not be used as a weight-loss or diabetes claim. Pen-cartridge hardware belongs to licensed drug–device combinations. That does not authorise this listing as a consumer refill.
