Elon Musk has been open about his weight loss journey. He stated that he uses Wegovy, which contains semaglutide as its active ingredient. Wegovy is a weekly injectable medication that was first created for diabetes management. Now the FDA has approved it for chronic weight management.

Semaglutide works in three main ways:
- It suppresses appetite
- It regulates hunger hormones
- It slows down digestion
This helps people feel full longer and eat less food overall.
Semaglutide is technically a peptide. It mimics a hormone called GLP-1 that occurs naturally in your body. This hormone helps control blood sugar and appetite.
While Musk has confirmed using Wegovy, he hasn't publicly mentioned using other of the best peptides for weight loss that some people try, such as:
- CJC-1295
- Ipamorelin
- AOD-9604


Musk's weight loss results came from a combination of factors. The medication was just one part of his approach. He also mentioned improving his diet and exercise habits.
Many people wonder if peptides really work for weight loss. The research shows that certain peptides like semaglutide can be effective, but they work best when combined with lifestyle changes.
