Potential Benefits

Key advantages and therapeutic effects

1

Major Weight Loss

  • One of the biggest benefits is very large weight reduction
  • Clinical trials show about 17-24% body weight loss in ~48 weeks
  • Later trial data reported around 26-28% average weight loss over 68 weeks
  • Among the highest results ever seen for an obesity medication
2

Strong Appetite Suppression

  • Retatrutide activates GLP-1 and GIP receptors, which:
  • Reduce hunger
  • Increase feelings of fullness
  • Slow stomach emptying
  • This naturally leads to lower calorie intake
3

Burns More Calories (Higher Metabolism)

  • Unlike some weight-loss drugs that mainly reduce appetite, retatrutide also increases energy expenditure
  • This happens because glucagon receptor activation:
  • Stimulates fat breakdown
  • Increases metabolic rate
  • Encourages the body to use stored fat for energy
4

Improved Blood Sugar Control

  • Research shows it can:
  • Improve insulin sensitivity
  • Lower fasting glucose
  • Reduce HbA1c levels
5

Reduction of Body Fat (Especially Visceral Fat)

  • Studies indicate it reduces:
  • Visceral fat (dangerous belly fat)
  • Total body fat mass
  • Some studies show over 26% reduction in fat mass while maintaining lean mass
6

Potential Heart & Metabolic Benefits

  • Early data suggests improvements in:
  • Cholesterol and lipid profile
  • Blood pressure
  • Inflammation markers
  • These changes could support better cardiovascular health

Injection Sites

Recommended locations for administration

UPPER ARMS

Triceps area. If someone else is administering your subcutaneous injection. May also inject into the fleshy area on the back of your upper arm. This area isn't recommended for self-injection because it is difficult to reach and see while using proper technique.

ABDOMEN

Below your ribs and above your hip bones, at least 2 inches away from your belly button. Most people can easily reach because it's easy to see and reach — ideal for self-administering. Also, some research suggests subcutaneous injections in the abdomen may be less painful than the thigh.

THIGH

When injecting into your thigh, aim for the front or the outer sides. It's ideal to avoid injecting into the inner part of your thigh.

Rotate injection sites each week to keep skin healthy and medication effective. Avoid areas that are scarred, bruised, or irritated.
