TL;DR: Key points with love ❤️

The "microdosing" trend for GLP-1 weight loss drugs like Ozempic, Mounjaro, and Wegovy is spreading from the US to the UK. This off-label practice involves taking reduced doses to curb hunger and achieve gradual weight loss, appealing to individuals who don't meet the criteria for standard prescriptions. While private clinics offer it and some users report benefits like reduced inflammation, medical experts warn of unpredictable outcomes due to lack of scientific evidence and safety data.
