Retatrutide 20mg + Trizepatide 40mg
€1,140.00
Retatrutide 20mg + Tirzepatide 40mg is a high-potency research combination of the two most powerful weight loss peptides in clinical development. Together, these compounds target the GIP, GLP-1, and glucagon receptors with the strongest available affinity. Supplied as lyophilized powder with ≥98% purity (HPLC-verified).
How They Work Together
Retatrutide already hits three targets (GIP, GLP-1, and glucagon), producing up to 24.2% weight loss. Tirzepatide is the most potent dual GIP/GLP-1 agonist, producing up to 22.5% weight loss. The combination intensifies the GIP and GLP-1 signal while adding glucagon-mediated energy burning — creating unprecedented metabolic pressure on body weight.
Weight Loss Research Data
- Retatrutide (NEJM 2023): 24.2% mean body weight reduction at 48 weeks. 100% of subjects achieved ≥5% weight loss.
- Tirzepatide (SURMOUNT-1, NEJM 2022): 22.5% mean body weight reduction at 72 weeks. 96% achieved ≥5% weight loss.
- Both compounds individually rank as the two most effective weight loss medications ever studied in clinical trials.
- The combination at these higher doses represents an intensified research approach for studies of maximum metabolic intervention.
Research Applications
- Maximum-efficacy multi-receptor obesity pharmacology
- Dose-response and synergy studies of incretin agonists
- Advanced metabolic research models
- Comparative efficacy analysis between receptor targets

Community Buzz
This blend intensifies the GLP-1/GIP signal by combining Retatrutide with Tirzepatide — both hit GLP-1 and GIP, creating a stronger dual-receptor effect, while Retatrutide adds its unique glucagon-powered metabolic boost. The community calls this “overlapping intensification” — more receptors activated, stronger overall signal. No clinical data exists for this specific combination, placing it firmly in extreme biohacking territory. Users report it as the strongest appetite suppression and fat-burning experience available.
Why People Are Interested
- Intensified GLP-1/GIP signal. Two agonists hitting the same receptors for a stronger combined effect.
- Glucagon metabolic boost. Retatrutide adds the unique calorie-burning benefit to Tirzepatide’s dual mechanism.

Delivery Time: 6 to 12 business days worldwide.
Tracking: A tracking number is provided via email once your order has been dispatched.
For any questions regarding your shipment, please contact our support team.
All peptide products are supplied as a lyophilized (freeze-dried) powder in sterile glass vials. Lyophilization preserves the peptide's structural integrity and biological activity during transport and storage. The powder must be reconstituted with an appropriate solvent before use in research protocols.
Recommended Solvent
For most peptide research applications, we recommend using Bacteriostatic Water (BAC) — sterile water containing 0.9% benzyl alcohol as a bacteriostatic agent. BAC water helps maintain sterility after reconstitution and is suitable for multi-dose research protocols.

Reconstitution Protocol
- Prepare: Clean your work surface and ensure all materials (vial, BAC water, syringes) are handled in a sterile manner.
- Calculate: Determine the desired concentration by dividing the peptide mass (mg) by the volume of BAC water added (mL). For example, adding 2 mL of BAC water to a 5 mg vial yields a concentration of 2.5 mg/mL.
- Reconstitute: Using a sterile syringe, draw the calculated volume of BAC water. Insert the needle through the rubber stopper at an angle and slowly inject the solvent down the inner wall of the vial — avoid directing the stream directly onto the powder to prevent foaming.
- Dissolve: Gently swirl the vial (do not shake) until the powder is fully dissolved. Most peptides dissolve within 1-2 minutes. A clear, colorless solution indicates complete dissolution.
- Aliquot: For long-term use, transfer the reconstituted solution into sterile aliquots to avoid repeated freeze-thaw cycles of the original vial.
Post-Reconstitution Storage
- Store reconstituted peptide solution at 2-8°C for short-term use (up to 7 days).
- For extended storage, aliquot and freeze at -20°C. Avoid repeated freeze-thaw cycles.
- Always label aliquots with peptide name, concentration, date, and storage conditions.
Note: The optimal solvent and reconstitution protocol may vary depending on the specific peptide and research application. Researchers should consult peptide-specific literature for solubility guidance.
