Retatrutide
Next-Generation Weight Loss

Starting at $300

The world's first triple incretin agonist — activating GLP-1, GIP, and glucagon receptors simultaneously. Phase 2 data produced weight loss results that rival bariatric surgery.

Retatrutide medication
Triple-receptor activation

GLP-1 + GIP + Glucagon

Retatrutide is the first investigational drug to simultaneously activate three distinct metabolic hormone receptors — creating a synergistic metabolic response more powerful than any existing approved therapy.

Unprecedented efficacy

24.2% average weight loss

Phase 2 data produced 24.2% mean body weight reduction at 48 weeks — the highest ever reported for a pharmacological agent in a controlled trial, approaching the outcomes of bariatric surgery.

Metabolic rate boost

Glucagon activation advantage

Uniquely, retatrutide activates the glucagon receptor — increasing resting energy expenditure and promoting fat oxidation. This 'energy out' mechanism is absent in GLP-1 and dual-agonist therapies.

The Science, in Full Detail

We believe patients deserve to understand exactly how and why their treatment works.

Three receptors. One weekly injection.

Retatrutide activates GLP-1, GIP, and glucagon receptors simultaneously. Each pathway contributes a distinct mechanism of action — together producing a metabolic effect far beyond what single or dual-agonist therapies can achieve.

Get Started

GLP-1 Pathway

  • Slows gastric emptying — food moves through your stomach more slowly, extending fullness
  • Signals the brain's satiety centers to reduce hunger and 'food noise'
  • Glucose-dependent insulin release (safe blood sugar control)
  • Reduces inappropriate glucagon secretion

GIP Pathway

  • Enhances the GLP-1 signal — amplifies satiety signaling
  • Improves fat cell metabolism and reduces fat storage efficiency
  • Supports superior body composition outcomes vs. GLP-1 alone

Glucagon Pathway

  • Increases resting metabolic rate and energy expenditure
  • Promotes mobilization and oxidation of fat stores
  • Improves body composition — preserves lean mass

Side effects, honestly

We believe informed patients get better outcomes. Here's exactly what clinical trials report — with context on how common each effect is and how to manage it.

Nausea

Very Common

Severity: Mild–Moderate

Most intense during titration. Usually resolves within 2–3 weeks of each dose increase. Eating smaller, more frequent meals helps.

Constipation

Common

Severity: Mild

GI motility slowing is part of mechanism. Adequate hydration, fiber, and physical activity help.

Vomiting

Common

Severity: Mild–Moderate

More common at higher doses or fast titration. Slowing escalation pace reduces incidence significantly.

Decreased Appetite

Very Common

Severity: Intended effect

Primary mechanism of action. Providers monitor to ensure adequate protein and nutrition intake.

Fatigue

Common

Severity: Mild

Usually transient in first weeks after dose increase. Ensuring sufficient caloric intake helps.

Diarrhea

Common

Severity: Mild

Often transient during dose escalation. Stay well-hydrated and consider fiber supplementation.
