The three receptors belong to the same structural class and couple to the same stimulatory G protein, which activates adenylyl cyclase and raises cyclic AMP. That shared pathway is what makes a single assay format applicable to all three.
It is also why a single peptide can be tuned across them: the receptors are related enough for one sequence to engage more than one.
A cell line is made to express one receptor and none of the others. Compound is added across a concentration series, cAMP is measured, and the concentration producing half the maximal response is the potency. Running the same assay in three cell lines gives three potencies, and comparing each to the native hormone gives relative potency.
The discovery paper reports these for retatrutide, and the engineered imbalance across the three is read directly from them.
Potency in an engineered cell line is a property of the receptor-compound pair under those conditions. It does not predict distribution, duration or effect in an organism, and the ratio between receptors in a dish is not necessarily the ratio of effects in a person.
The assay is where characterisation starts, and the trials are where the question of effect is answered.
Retatrutide is supplied by REVIVE LAB UAE as an investigational research material for laboratory use only, with identity by mass spectrometry and purity by HPLC for the batch. It is not approved for any use anywhere, and no dosing, administration or protocol guidance is provided.
