The Science
Retatrutide is the first triple-pathway agonist — it activates GLP-1, GIP and Glucagon receptors simultaneously. Where semaglutide engages one receptor and tirzepatide two, the third (glucagon) pathway adds increased energy expenditure on top of appetite suppression: the body burns more at rest while eating less.
GLP-1 receptor
Suppresses appetite, slows gastric emptying, improves insulin response — the foundation pathway.
GIP receptor
Improves fat metabolism and insulin sensitivity, layered with the other two pathways.
Glucagon receptor
The unique third lever — raises basal energy expenditure so you burn more calories at rest.
Why in-Thailand sourcing matters
Direct sourcing — no overseas shipping risk
Our Asia-based pharmaceutical-grade supplier route stays within Thailand. Intercontinental shipping adds 18–72 hours of cold-chain transition points; our pharmacy-to-clinic workflow avoids them.
Licensed pharmacist-verified supply chain
Raw materials verified via HPLC and mass spectrometry to confirm potency and authenticity prior to dispense.
Medical-grade, COA-certified, GMP-compliant
Manufacturing under Good Manufacturing Practice with a full documentation trail from raw-material lot to dispense.
Local regulatory compliance
Dispensed under Thai pharmacy law with continuous 2–8°C cold-chain logistics to the clinic and to your address.
Treatment Protocol
Designed individually by treatment response — not by a fixed schedule. Many patients reach their goal in Months 1–3 alone and stay there long-term. Step-up to higher doses happens only if your individual response plateaus. Gradual titration keeps side effects minimal.
Months 1–3
2 mg/week
Initial response phase. Many patients see significant results here and stay long-term — no escalation needed.
Months 4–6
4 mg/week
Optional step-up only if Months 1–3 plateau. Decision based on individual response.
Months 7–9
6 mg/week
Reserved for plateaus from Months 4–6. Stepped up only if medically indicated.
Months 10–12
8–12 mg/week
Maximum-efficacy phase. Highest individual response targets. Goal-weight maintenance + sustainable exit plan.
No automatic escalation. Dose escalation happens only when medically needed — adjusted individually by treatment response and weight target by our peptide protocols team.
How the protocol works
Every month includes lab-verified, pharmacist-compounded vials with supervised dosing, cold-chain delivery, a sterile injection kit and ongoing medical support — all confirmed in a private consultation, no hidden fees.
Months 1–3
2 mg/week
1 × 10 mg vial / month
Initial response phase. Baseline review + first injection guided at the clinic. Many patients reach their goal here.
Months 4–6
4 mg/week
2 × 10 mg vials / month
Optional step-up only if Months 1–3 plateau. Decision based on individual response.
Months 7–9
6 mg/week
3 × 10 mg vials / month
Reserved for plateaus from Months 4–6. Stepped up only if medically indicated.
Months 10–12 (8–12 mg/week): customized in a private consultation based on your individual dose-response.

Your cost depends on your dose and how long you stay on the protocol. It starts at 2 mg/week (one 10 mg vial per month) and steps up only if clinically indicated — 4 mg/week, then 6 mg/week, toward an 8–12 mg/week maintenance target. Every tier includes lab-verified, pharmacist-compounded vials with supervised dosing, cold-chain delivery, a sterile injection kit and ongoing support from our medical team. Your exact figure is confirmed in a private consultation — Thai pharmacy advertising rules preclude binding online prices.

No automatic escalation — every step is adjusted individually by our peptide protocols team.
Add bacteriostatic water (typically 2 ml), swirl gently — never shake — and refrigerate at 2–8°C. Use the dosing calculator above for your exact draw in insulin units; our nurse demonstrates the full process at your first visit.

Most commonly mild nausea and GI discomfort during the first weeks of titration; the gradual dose-escalation protocol minimizes these. Our peptide protocols team reviews your medical history and current prescriptions before any treatment decision.
Product is checked by HPLC and mass spectrometry through our licensed compounding pharmacy and kept under continuous 2–8°C cold-chain — verified at the point of dispense, not from an anonymous online seller.
