US health spending hit $5.7 trillion in 2025, up 7.3%, and GLP-1 drugs like semaglutide and tirzepatide are a named driver. Here is what the numbers say.
One blood test, 54 peptide doping agents
A 2026 Ghent University method screens 54 peptide and non-peptide doping agents, including TB-500 and BPC-157, in dried and liquid blood in a single fast run.
Semaglutide and the cost of CV benefit
A 2026 cost-effectiveness review places semaglutide, a GLP-1 agonist, in the moderate tier for preventing cardiovascular events. Here is what that means.

A 2026 meta-analysis of six trials links semaglutide to lower NT-proBNP, better symptom scores and fewer heart-failure hospitalisations in obesity-driven HFpEF.
How semaglutide works across the body
A 2026 review reads semaglutide through a systems medicine lens, tracing the GLP-1 receptor agonist from trial outcomes to the molecular mediators underneath.
Weight-loss drugs and hypertension
A Cochrane review of eight trials finds insufficient evidence that weight-loss drugs cut mortality or cardiovascular events in hypertensive patients.
Eating disorder screens predict GLP-1 use
A US survey of 1,309 adults links positive eating disorder screens to higher GLP-1 awareness and telehealth drug-seeking.
GLP-1 drugs improve ratio but cut muscle
A 2026 meta-analysis of 7 RCTs finds GLP-1 receptor agonists raise the lean-to-fat ratio while causing a 1.74 kg average absolute lean mass loss.
GLP-1 drugs and lung safety: what we know
