Retatrutide 15mg
Triple GLP-1 / GIP / glucagon receptor agonist
Catalogue category: GLP / Weight Loss
Retatrutide is the metabolic line in this group and the reason the four are usually discussed together. It acts on three receptors — GLP-1, GIP, and glucagon — rather than the single GLP-1 target older agonists rely on, which is why it sits in the GLP / Weight Loss catalogue category by itself rather than alongside the recovery peptides. The 15 mg vial is the smallest of the three published sizes on the supplier's listing; the heavier sizes (20 mg, 30 mg) cost less per milligram and tend to be what researchers move to after the entry vial. Because the line carries the largest share of the total cost across the four, it is the one most people order separately first if they're working to a budget.
