WHY LOCALLY-SOURCED MATTERS

Cold-chain integrity + verified pharmaceutical-grade quality

Peptides like Retatrutide require strict 2–8°C cold-chain maintenance throughout the entire supply chain. Where our Investigational Therapy Program operates, source quality matters more than distance traveled.

Local supply-chain stability

Peptide stability is sensitive to temperature deviations. Intercontinental shipping (typically 18–72 hours flight + customs + last-mile delivery) introduces multiple cold-chain transition points. Our Bangkok-based supply route reduces these transitions significantly — direct pharmacy-to-clinic workflow under continuous 2–8°C protocol.

Verified at point of dispense

Our Investigational Therapy Program partners with an Asia-leading licenced and accredited compounding pharmacy in Bangkok (10+ years of service to hospitals and clinics across the region). Raw materials are verified via HPLC (High-Performance Liquid Chromatography) and mass spectrometry to confirm potency and authenticity prior to dispense.

GMP-compliant manufacturing

Our supply partner operates under Good Manufacturing Practice (GMP) protocols and internationally recognized ISO-quality standards. All products maintain documentation trail from raw-material lot through dispense — supporting your doctor's review process and your peace of mind.

Physician medical review

Before any decision, our supervising physician reviews your current prescriptions, medical background, and individual eligibility — ensuring any considered treatment fits your overall health context. No standardized "one-size-fits-all" approach. Personalized, evidence-based, conservative.

The Science

What is Retatrutide?

Retatrutide is the first investigational medicine to activate three different gut-derived hormone receptors simultaneously — GLP-1, GIP, and Glucagon. Where Tirzepatide engages two receptors and Semaglutide engages one, the triple-agonist design adds glucagon-receptor stimulation, which increases energy expenditure on top of appetite suppression. In the Phase 2 obesity trial, patients on the highest dose demonstrated mean body-weight reduction of 24.2% over 48 weeks[1] — the strongest published outcome among incretin-class medicines to date. Phase 3 trials in the TRIUMPH program are ongoing[3].

GLP-1 Receptor

Slows gastric emptying, suppresses appetite, improves insulin response. The foundational pathway shared with Semaglutide and Tirzepatide.

GIP Receptor

Improves fat metabolism and insulin sensitivity. Shared with Tirzepatide — but in Retatrutide, layered with the third receptor for greater combined effect.

Glucagon Receptor

The unique addition. Glucagon-receptor activation increases basal energy expenditure — the body burns more calories at rest, on top of eating less. This third lever differentiates Retatrutide from all approved alternatives.

For the broader weight-loss medicine landscape including FDA-approved alternatives, see our Weight Loss Thailand overview or the Tirzepatide and Semaglutide pages.

Next-Generation Protocol · Private Eligibility

How to access the Retatrutide protocol

Retatrutide is the world's first Triple-G Pathway agonist — targeting GLP-1 (appetite/digestion), GIP (fat/sugar metabolism) and Glucagon (energy expenditure). In TRIUMPH Phase 2 trials, mean body-weight reduction reached 24.2% at 48 weeks (highest dose) — the highest documented for any weight-loss molecule in this timeframe. Phase 3 trials (TRIPHASE program) are ongoing worldwide · expected FDA-approval window 2025–2026. Our Investigational Therapy Program educates eligible patients about Retatrutide while supporting your current best-fit treatment (Mounjaro, Wegovy, Tirzepatide).

Book a consultation through our Investigational Therapy Program to (1) discuss your current best-fit GLP-1 treatment today, (2) get an educational review of Retatrutide's trial data and timeline, and (3) be among the first informed when approval reaches your jurisdiction.

Titration Protocol

Standard 4-Step Dose-Escalation

Retatrutide follows a 4-step titration protocol matched to the TRIUMPH trial design — 4 weeks at each dose level to allow GI adaptation before stepping up.

Weeks 1-4
2 mg weekly
Adaptation phase. GI system acclimates to triple-receptor engagement.
Weeks 5-8
4 mg weekly
First sub-therapeutic step. Side-effect profile reviewed before further escalation.
Weeks 9-12

Maintenance dose for patients pursuing the full TRIUMPH efficacy. Some patients respond at lower doses and hold there.

Frequently Asked

Common Questions About Retatrutide

How does Retatrutide compare to Mounjaro?
Mounjaro (Tirzepatide) activates two receptors (GLP-1 + GIP) and produces 20-22% body weight loss in trials. Retatrutide adds a third receptor (Glucagon) for additional energy expenditure, demonstrating 24%+ weight loss in clinical research. The trade-off: Tirzepatide has FDA approval and longer real-world safety data; Retatrutide is the latest research-frontier option. Read more on our Tirzepatide Thailand page.
How do I get access to Retatrutide?
Request a private consultation through WhatsApp. Each inquiry is reviewed individually by your supervising physician — eligibility, protocol, sourcing, and access are discussed during a confidential private consultation. Information is not published publicly.
What are the side effects of Retatrutide?
Most common: nausea and mild GI discomfort during the first 4-8 weeks of titration. The 4-step dose escalation protocol minimizes these effects. Rare but serious considerations include pancreatitis history and medullary thyroid cancer family history — discussed individually during consultation.
How long does Retatrutide titration take?
Standard titration is 12-13 weeks: 2 mg, then 4 mg, then 8 mg, then 12 mg, with 4 weeks at each step. Maintenance dose is then continued for 6-12 months depending on weight-loss goals. Some patients respond at lower maintenance doses.
Can international patients access Retatrutide?
Many international patients have requested consultations. Access depends on local regulations in your country. We discuss your specific situation during the private consultation — including delivery options where legally permitted. See our International Patients page for travel and shipping options.
Is Retatrutide available at TRT Bangkok today?
Retatrutide is currently in Phase 3 clinical trials — not yet approved by FDA or Thai FDA. We do not prescribe Retatrutide today. Our consultations focus on your current best-fit GLP-1 treatment (Mounjaro, Wegovy, Tirzepatide) and educate you on Retatrutide's expected approval timeline so you can plan ahead.
How is Retatrutide stored and shipped?
Cold-chain handling throughout — refrigerated storage from sourcing to clinic to patient. Insulated shipping with temperature monitoring. Patients receive storage instructions for home use (refrigerator, do not freeze).
