2. What is Tirzepatide?

Tirzepatide is a novel dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist. Key points:

  • Synthetic peptide comprising 39 amino acids

  • Conjugated to a C20 fatty diacid moiety

  • Marketed as Mounjaro (for diabetes) and Zepbound (for weight loss)

  • Approved by FDA in May 2022 for type 2 diabetes and November 2023 for weight loss

  • Unique "twincretin" mechanism of action

3. Tirzepatide Mechanism of Action

Tirzepatide works through several mechanisms:

  1. Stimulates first- and second-phase insulin secretion

  2. Reduces glucagon levels in a glucose-dependent manner

  3. Delays gastric emptying

  4. Lowers fasting and postprandial glucose concentrations

  5. Decreases food intake

  6. Reduces body weight

  7. Increases insulin sensitivity

4. Research Applications and Potential Benefits of Tirzepatide

Tirzepatide and Type 2 Diabetes

  • Significant reduction in HbA1c levels (maximum reduction of 2.46%)

  • Substantial improvements in fasting and postprandial glucose levels

Tirzepatide and Weight Loss

  • Substantial weight loss (up to 22.5% of body weight in clinical trials)

  • Improvements in waist circumference and body composition

Tirzepatide and Cardiovascular Health

  • Reduction in blood pressure

  • Improvements in lipid profiles

  • Potential cardiovascular benefits under investigation in ongoing trials

Tirzepatide and Nonalcoholic Steatohepatitis (NASH)

  • Ongoing research into potential benefits for liver health

5. Tirzepatide Dosage Guide

Dosing Tirzepatide for Type 2 Diabetes

  • Starting dose: 2.5 mg once weekly

  • Increase to 5 mg once weekly after 4 weeks

  • Further increases in 2.5 mg increments every 4 weeks as needed

  • Maximum dose: 15 mg once weekly

Dosing Tirzepatide for Weight Loss

  • Same dosing schedule as for type 2 diabetes

6. How to Mix and Administer Tirzepatide

Tirzepatide comes as a pre-filled, single-dose pen and does not require mixing.

  5. Dispose of used pen in a sharps container

7. Tirzepatide Administration Methods

Tirzepatide is administered via subcutaneous injection only.

8. Tirzepatide Combinations and Interactions

  • May be used with metformin, SGLT2 inhibitors, and other diabetes medications

  • Caution advised when used with sulfonylureas or insulin due to hypoglycemia risk

  • May affect absorption of oral medications due to delayed gastric emptying

9. Where to Buy Tirzepatide Online | 2024 Edition

Tirzepatide is a prescription medication and should only be obtained through licensed pharmacies with a valid prescription.

10. Is Tirzepatide Safe?
