Potential side effects
GLP-1 injections may cause nausea, diarrhea, or vomiting. To help manage symptoms while your body adjusts, eligible patients may add a fast-acting anti-nausea medication.

Why GLP-1s
Natural hormone breaks down in minutes. GLP-1s last days.
Natural GLP-1 lasts ~2 minutes
Every time you eat, your gut releases a hormone called GLP-1 that signals fullness, triggers insulin release, and slows digestion. An enzyme called DPP-4 destroys it within 1 to 2 minutes.

GLP-1 receptor agonists are lab-engineered versions of this hormone, modified to resist DPP-4 breakdown and stay active long enough to sustain appetite control and blood sugar regulation.

The result: half-lives ranging from 2.5 hours to approximately 7 days — up to 5,000 times longer than the natural hormone.

How GLP-1 RA works
Tirzepatide activates both GLP-1 and GIP receptors.
Tirzepatide is a dual GLP-1 and GIP receptor agonist that mimics two gut hormones. Receptors are located in the brain, gut, heart, and pancreas, where activation supports appetite regulation, blood sugar balance, and metabolic function.
Activates GLP-1 and GIP 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.

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 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. 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 Tirzepatide Microdose is appropriate for you.
