01 / What is it?
What is it?
Retatrutide is a peptide that acts on three signalling systems in the body: GLP-1, GIP and glucagon. These signals are involved in hunger, feeling full, blood-sugar control and the way the body uses energy.

Retatrutide
Why do people find it interesting?
People taking retatrutide often reported less hunger and feeling full sooner. It helps burning fat reserves.
What might you notice?
Possible effects include less hunger, feeling full after smaller meals and weight loss over time.
What happens in your body?
GLP-1 and GIP help the body release insulin when needed and send fullness signals to the brain. They can also slow down how quickly food leaves the stomach. Glucagon affects how the body manages stored energy. Retatrutide activates all three systems at the same time, which is why it has a direct effect on appetite, weight and metabolism.
Keep the context
Important to know
Stomach problems are common, especially when you start or increase the dose. These can include feeling sick (nausea), vomiting, diarrhea, constipation, stomach pain and bloating.

Dose information from the guide
People usually start with a low dose (for example 1.5 mg - 2 mg once a week) and slowly go up to 2 mg - 4 mg, 8 mg or 12 mg, if they can tolerate it. Do not double a dose to make up for a missed injection. This guide also warns against giving two injections close together and describes keeping at least 3–4 days between injections and using the same day each week where possible.
