Sustainable metabolic health requires preserving lean mass, restoring metabolic resilience, and building habits that outlast the prescription
Through a retrospective review of cutaneous adverse events associated with semaglutide, dulaglutide, tirzepatide, lixisenatide, liraglutide, and exenatide in the FDA Adverse Event Reporting System, it was found that the 5 most common cutaneous reactions associated with GLP-1 agonists were eczematous, pruritus, drug eruptions, hyperhidrosis, and alopecia
Initial studies in rats caused concerns over GLP-1 RAs causing thyroid cancer, but human studies are less clear on whether it is a concern.[ref] Decreased risk of substance abuse: A large 2026 study using data from the VA showed that GLP-1 RA drugs reduce the risk of developing a substance addiction (drugs, alcohol)

These benefits have been demonstrated in large, well-designed cardiovascular outcome trials, including: Liraglutide (Victoza) the LEADER trial , which showed a significant reduction in cardiovascular death and all-cause mortality Semaglutide (Ozempic) the SUSTAIN-6 trial , demonstrating fewer major adverse cardiovascular events, particularly stroke Dulaglutide (Trulicity) the REWIND trial , which showed a significant reduction in major cardiovascular events even in people without established cardiovascular disease Tirzepatide (Mounjaro) cardiovascular outcome data from the SURPASS-CVOT programme are emerging, with early results suggesting cardiovascular benefit compared with insulin therapy These cardiovascular effects are a key reason why GLP-1based therapies are now recommended earlier in the treatment pathway for people with type 2 diabetes who have established heart disease or are at high cardiovascular risk
