retatrutide versus tirzepatide vs for weight loss Retatrutide vs. Tirzepatide for Weight

Semaglutide must be stored refrigerated (36-46F) before use

Avoid sudden, large drops in glucose by aiming for steady improvements

Stress signals the hypothalamus (the part of the brain that regulates body functions) to release cortisol

Tirzepatide is the FDA-approved two-receptor drug (GLP-1/GIP) with about 20.9 percent average weight loss at top dose

Key points GLP-1 is a hormone that increases insulin release and prevents the release of too much glucagon, helping manage blood glucose levels in individuals with type 2 diabetes GLP-1 receptor agonists, such as liraglutide and semaglutide, effectively reduce blood glucose levels Semaglutide is more effective than liraglutide at reducing blood sugar levels Tirzepatide is a newer GLP-1 receptor agonist that also mimics the actions of another hormone called GIP, which can also reduce blood sugar levels A randomised controlled trial showed that tirzepatide led to more significant blood sugar reductions than semaglutide across three doses Tirzepatide may be more effective than semaglutide at higher doses, but this needs further investigation Liraglutide and semaglutide are available in the UK and the US, while tirzepatide is only available in the US but is likely to be approved in the UK soon
