What it is
GLP3 (Reta) refers to retatrutide, an investigational peptide that acts on three metabolic receptors — GLP-1, GIP, and glucagon — rather than the single or dual pathways used by earlier metabolic peptides.
How it's described to work
GLP-1 and GIP signaling influence appetite regulation, gastric emptying, and insulin response, while glucagon signaling is associated with energy expenditure. Studying all three together is why researchers describe it as a 'triple agonist'.

Important context
Retatrutide is investigational and is discussed here for education only. Any metabolic protocol at Mobile Drips begins with labs, a health history review, and a telehealth consult with a licensed provider.
