GLP-1 receptors are expressed in pancreatic islet -cells, pulmonary epithelial cells, atrial cardiac myocytes, vagal afferent neurons, neurons in a number of brain regions, as well as cells lining gastric pits and small intestinal mucosa
If used for diabetes care, consult with an endocrinologist to possibly bridge therapy to minimize the risk of hypoglycemia
Of course, there is a theoretical performance advantage in sports that have weight classes or sports like cycling and long distance running where weight is a factor, but because the GLP-1s suppress appetite and cause muscle loss as well as fat loss, they arent necessarily going to improve performance. However, Eichner also points out that not much is known about potential performance-enhancing effects of GLP-1s, and more research needs to be done
What the GLP-1 Side Effects Timeline Actually Looks Like A timeline can help set expectations, but it should not be treated like a countdown clock
We also attempted replication analysis in the UK Biobank cohort, although the available data predate the availability of semaglutide or tirzepatide, and hence relied on earlier variants of GLP1 receptor agonists
