Is retatrutide the same as tirzepatide (Mounjaro)?
Retatrutide and tirzepatide are different drugs with different chemical compositions. While retatrutide mimics three hormones to support weight loss, tirzepatide mimics two.
Still, weight loss outcomes on retatrutide and tirzepatide are similar based on the research conducted so far.
Tirzepatide supports an average weight loss of around 25% after 52 weeks. On retatrutide, it’s around 24% after 48 weeks.
However, as we don’t have longer-term research investigating the impact of retatrutide on weight loss after 48 weeks, it’s unclear whether patients would continue to lose weight beyond this.
Additionally, losing over 20% of your body weight in one year is quite sufficient for most and would lead to substantial health improvements. Not everyone would necessarily need to lose more than this to promote good health in the long term
