Knowing your peptide-pathway genetic profile can enrich conversations with your provider about whether liraglutide aligns with your biology, whether dosing adjustments might optimize results, or whether an alternative GLP-1 agent (semaglutide, tirzepatide) better suits your genetic predispositions
The serum actually brightens the skin very well
Key Points Genetics probably plays a part in GLP-1 response, but it is not the main practical explanation in most cases A new Nature paper found GLP1R and GIPR variants associated with efficacy and side effects, but effect sizes are modest Non-genetic factors drug choice, dose, duration, sex, diabetes status still explain more variation than genetics Current evidence does not justify routine genetic testing before prescribing semaglutide or tirzepatide Most apparent non-responders have correctable clinical reasons for poor response If you are wondering why GLP-1 drugs work better for some people , the short answer is this: genetics probably plays a part, but it is not the main practical explanation in most cases
Alongside these medical advancements, there is a growing recognition of the need to address the broader social and environmental drivers of obesity
