WHY GLP-1s

Natural hormone breaks down in minutes. GLP-1s last days.

HOW GLP-1 RA WORKS

Tirzepatide activates both GLP-1 and GIP receptors.

Tirzepatide is a GLP-1 receptor agonist that mimics the GLP-1 hormone produced in the gut. Receptors are located in the brain, gut, heart, and pancreas, where activation supports appetite regulation, blood sugar balance, and metabolic function.

Activates GLP-1 receptors

Your gut releases two metabolic hormones after eating: GLP-1 and GIP. Both regulate blood sugar, appetite, and energy use, but they break down in minutes. Tirzepatide activates both pathways and lasts roughly 5 days.

Preserves benefits

Research suggests that low dose tirzepatide can activate longevity-relevant pathways including moderate weight loss, glycemic control, and anti-inflammatory effects.

Can Reduce side effects

Tirzepatide side effects may scale with dose. In clinical trials, cutting the dose from 15 mg to 5 mg reduced nausea by one-third.

COMMON QUESTIONS

Questions, answered

What is Tirzepatide Microdose?

Tirzepatide activates longevity pathways tied to weight loss, glycemic control, and reduced inflammation by engaging both GLP-1 and GIP — the gut hormone signals that regulate appetite, blood sugar, and how the body stores and uses energy.

Early research suggests these pathways may retain healthspan benefits even at lower doses, opening the door to personalized protocols that preserve the metabolic effects while often reducing side-effect burden.

How do you take Tirzepatide Microdose?

Tirzepatide Microdose is available via Immortals Medicine in a weekly injectable form. Your provider will determine which medication and dose is appropriate for you. Always follow instructions from your doctor.

What are the side effects of Tirzepatide Microdose?

Higher doses of tirzepatide are associated with more side effects.

In clinical trials, 18% of patients experienced nausea at 15 mg compared to 12% at 5 mg — a 6 percentage point reduction.

At full dose, the most common side effects are nausea, vomiting, diarrhea, constipation, abdominal discomfort, and decreased appetite. Lower doses and slower titration can reduce the frequency of these side effects. Your provider will discuss side effects with you, along with dosing instructions.

Who shouldn’t take Tirzepatide Microdose?

Not recommended for people with a personal or family history of medullary thyroid cancer or MEN2. Your doctor will evaluate whether Personalized Tirzepatide is appropriate for you.
