Retatrutide — The Next-Generation Weight Loss Injectable Now Available in Thailand

In 2025, the world of weight management treatments took a major leap forward with the arrival of Retatrutide — a revolutionary triple-agonist peptide that has already outperformed popular drugs like Semaglutide (Ozempic) and Tirzepatide (Mounjaro) in clinical trials.

Now available in Thailand under the STbio brand, the convenient 30mg pre-filled FlexPen makes this powerful compound accessible with cold chain delivery for maximum safety and effectiveness.

🔬 What is Retatrutide?

Retatrutide is a breakthrough investigational drug designed for treating obesity, type 2 diabetes, and metabolic disorders. It works as a triple agonist that targets three critical metabolic pathways:

• GLP-1 (glucagon-like peptide-1): reduces appetite, delays gastric emptying, improves satiety.

• GIP (glucose-dependent insulinotropic polypeptide): enhances insulin secretion post-meal.

• Glucagon receptor agonist: boosts fat-burning (lipolysis) and increases energy expenditure.

This synergistic action provides superior results in both weight loss and metabolic control compared to previous-generation drugs.

⚖️ Clinical Results — How Effective is Retatrutide?

In Phase II clinical trials, Retatrutide demonstrated unprecedented results:

• Up to 24% weight loss over 48 weeks in obese individuals

• Improved insulin sensitivity and HbA1c reduction

• Fewer gastrointestinal side effects than GLP-1 monotherapy

Comparison to existing injectables:

• Semaglutide: ~15% weight loss

• Tirzepatide: ~20%

• Retatrutide: Up to 24%+

This makes it the most promising weight loss compound to date.

Gradual titration minimizes nausea or digestive discomfort, allowing for optimal tolerance.

🧬 Why Retatrutide Is Superior to Other Injectables

Compound	Mechanism	Weight Loss	Frequency	Side Effects
