Studies have shown that GHK also improves infection, wound healing, cognition and many other functions
A 2025 JAMA article found that when you stop semaglutide or tirzepatide, even after use of up to one year, there is rapid regain of weight and reversal of cardiovascular benefits
Such ratio significantly increased from baseline after 26 weeks of treatment with liraglutide 1.8 mg/day, indicating a reduction in liver steatosis, whereas it was unchanged in patients treated with lower doses of liraglutide, glimepiride or placebo
However, data from the past 2 years suggest that real-world persistence on these drug classes is often suboptimal, with many people discontinuing these medications, even within their first year of therapy
