Retatrutide is not yet licensed in the UK by the MHRA or EMA, and it is important to clarify that doses are measured in milligrams (mg), not 'units' as used for insulin
GLP-1 medications such as Ozempic and Wegovy have become increasingly common for weight management and metabolic health
People taking GLP-1s may experience fewer blood sugar spikes, less hunger, and quicker, longer-lasting fullness after meals
Switching from retatrutide to tirzepatide This direction is simpler because you are removing a receptor pathway rather than adding one: Stop retatrutide and allow 1-2 weeks washout Start tirzepatide at 2.5 mg per standard protocol Escalate normally every 4 weeks Expect potentially faster tolerance since your GLP-1 and GIP receptors already have exposure history Some researchers report smoother GI tolerance when switching from a triple to a dual agonist, which makes pharmacological sense
It helps improve insulin sensitivity, supports energy production, and enhances metabolic efficiency
In a retrospective cohort study, supplemented with a nested case-control study, using two US administrative databases, Liang et al (2019) found a non-significant trend toward increased risk of thyroid cancer with exenatide (OR 1.46, 95% CI 0.982.19) (9)
