Same receptors, different balances, different molecules

Published 24 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
Two agonists engaging the same set of receptors can differ in the relative potency at each, and that ratio determines the balance of effects. Retatrutide was engineered with reduced relative GLP-1 receptor potency and stronger GIP and glucagon receptor potency, as reported in its discovery paper. Another molecule at the same three receptors with a different ratio would be a different pharmacology.

Why ratio is a design variable

Each receptor contributes distinct effects. Shifting potency toward one shifts the balance of outcomes — and of adverse effects, since gastrointestinal events track GLP-1 receptor engagement. Designers choose a ratio to pursue a particular balance, and the choice is reported in the receptor assays.

For retatrutide the discovery paper describes the reduced GLP-1 potency as intended, to moderate gastrointestinal effects while the other two receptors carried more of the load.

How ratios are reported

As relative potencies from cAMP assays in cells expressing each receptor singly, compared against the native hormone. The numbers depend on assay conditions and are compared within a paper rather than across them. The discovery paper states them for retatrutide.

A secondary summary that says only "triple agonist" has dropped the ratio, which is the part that distinguishes one molecule from another.

What follows

Evidence for retatrutide is evidence for its ratio. If other triple agonists reach publication with different balances, their results will not describe retatrutide and the reverse will hold.
