What Retatrutide can do for you
Big weight loss
In a large study, people lost about 24% of their body weight in under a year. That is the most of any shot so far.
Shuts off cravings
It tells your brain you are full. You eat less without fighting hunger all day.
Burns more calories
Older shots only lower hunger. This one also tells your body to burn more energy, even at rest.
Melts belly and liver fat
Studies showed big drops in the deep fat around your organs, the most harmful kind.
Steadier blood sugar
Helps keep blood sugar level, so you get fewer crashes and snack attacks.
Just once a week
One tiny shot, same day each week. That's it.
How it works, in 10 seconds
Your gut makes hormones that tell your brain "I'm full." Retatrutide copies three of them at once. Older shots like semaglutide copy one. Tirzepatide copies two. Three switches is why this one works the hardest.
When you'll notice it
Most people feel less hungry in the first week or two. The scale usually starts moving in weeks 2–4.
How to take Retatrutide
Four numbers. Mix it, know what one line is worth, draw to the number, and know how often.

Good to know
💡 Good to know
- Stomach stuff like nausea and heartburn is worst in the first 2 weeks after each step up. Then it usually fades.
- Protect your muscle. Eat plenty of protein and lift weights. If you don't, a big chunk of what you lose is muscle, not fat.
- Coming off? Don't just stop. Cut your dose in half every 2–4 weeks on the way down.
⚠️ Be careful
- Never use it with semaglutide, tirzepatide, or any other GLP-1 shot. You stack the side effects, not the results.
- Skip it if you are pregnant, or if you or your family have had medullary thyroid cancer or MEN2.
