Retatrutide 15mg
Triple GLP-1 / GIP / glucagon receptor agonist
Category: Cutmaxxing
Retatrutide is the metabolic line of the clavstack and the reason the four compounds are usually discussed as one group. 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 Cutmaxxing category on its own rather than alongside the recovery pair. 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 this line carries the largest share of the clavstack total on its own, it is the compound most often ordered separately first when someone is clavmaxxing to a budget.
