GLP-1 receptor agonist drugs are large peptide molecules, around 3,000-4,000 Daltons, making the weight loss efficacy of GLP-1 patches ambiguous
[1] [2] Common GLP-1 medications include semaglutide (Ozempic, Wegovy), dulaglutide (Trulicity), liraglutide (Victoza, Saxenda), while tirzepatide (Mounjaro, Zepbound) is a dual GIP/GLP-1 receptor agonist
While semaglutide also causes GI side effects, its single-receptor mechanism (GLP-1 only, versus tirzepatide dual GLP-1/GIP action) produces a different pattern of gastric effects that some people tolerate better
Obesity and excess fat can have serious health effects across the lifespan, but particularly as people age
Advances in our understanding of nutrient partitioning, protein synthesis, and metabolic regulation have challenged this dogma, and compounds like Retatrutide may make body recomposition practically achievable for a broader population
Want to upgrade to stronger but cant seem to do that
