Triple-receptor metabolic signaling.
Retatrutide is a once-weekly investigational peptide that simultaneously activates GLP-1, GIP, and glucagon receptors — studied in clinical trials for effects on appetite, energy expenditure, and body composition beyond single- or dual-agonist approaches.
It is not FDA-approved for medical use. Natura ships it as a batch-verified research pen so you can titrate on a calibrated dial and read the lab paperwork before you open the box.
