Observed Risks in Clinical Trials
The most commonly reported adverse events in Phase 2 trials were gastrointestinal in nature. These included:
- Nausea (reported in up to 45% of participants at higher doses)
- Diarrhoea, vomiting, and constipation
- Decreased appetite
- Dose-dependent increases in heart rate were also observed

How to Use the Retatrutide Pen
Step-by-step instructions for handling your retatrutide pen. This guide is based on standard peptide pen administration procedures.
Dosing Context from Clinical Trials
In the Phase 2 NEJM trial, retatrutide was administered once weekly via subcutaneous injection. Doses were escalated from 0.5 mg starting dose up to a maximum of 12 mg over the 48-week study period. Dose escalation followed a protocol-defined schedule with increases at 4-week intervals. These are research protocols -- not prescribing instructions.
Prepare the Pen
Remove the retatrutide pen from refrigerated storage (2-8 degrees Celsius). Allow it to reach room temperature for approximately 30 minutes before use. Inspect the solution through the viewing window -- it should be clear and colourless. Do not use if discoloured or containing particles.
Attach the Needle
Remove a new pen needle from its sterile packaging. Align the needle with the pen tip and push straight on, then twist clockwise until secure. Remove the outer needle cap (keep it for disposal) and then the inner needle cap (discard). A small drop of liquid at the tip is normal.
Select the Dose
Turn the dose selector to set your prescribed dose. You will hear a click for each unit. The dose window will display the selected amount. If you set the wrong dose, simply turn the selector forwards or backwards to correct it without wasting any peptide.
Inject and Dispose
Pinch a fold of skin at the chosen injection site (abdomen, thigh, or upper arm). Insert the needle at a 90-degree angle. Press the dose button fully and hold for 10 seconds to ensure complete delivery. Release the skin, withdraw the needle, and apply gentle pressure if needed.
Pre-Injection Checklist
Regulatory Notice: Retatrutide is an investigational peptide. It has not been approved by SAHPRA (South African Health Products Regulatory Authority) for any medical indication. The usage information above is based on standard subcutaneous pen injection procedures and published clinical trial protocols. It does not constitute medical advice.
South African Customer Reviews
Feedback from verified Veyvora customers in South Africa. Reviews focus on product quality, packaging, and delivery experience.
Packaging was excellent -- arrived in insulated box with cold packs intact. Certificate of Analysis included as promised. Delivery took 6 business days to Sandton.
Very professional setup. Pen came with full batch documentation and clear instructions. Customs clearance was smooth, no issues getting it into SA.
CoA matched the batch number on the pen. Took about 8 days to arrive in Durban. Packaging was temperature-controlled and product was well-sealed.
Second order from Veyvora. Consistent quality between batches. The pen design is easy to use and the dosing markings are clear. Fast support response when I had questions.
Good communication throughout. Tracking was provided immediately. Product arrived well-packaged with all documentation. Would order again.
Impressed with the thoroughness -- batch records, CoA, storage instructions all included. This is the standard you expect from a research peptide supplier.

What Is Retatrutide?
Retatrutide (LY3437943) is an investigational triple hormone receptor agonist developed by Eli Lilly. Unlike single-receptor GLP-1 drugs such as semaglutide (Ozempic/Wegovy), or dual-receptor agonists like tirzepatide (Mounjaro), retatrutide activates three receptors simultaneously: GLP-1, GIP, and glucagon.
In Phase 2 clinical trials published in the New England Journal of Medicine (2023), participants receiving the highest dose of retatrutide experienced a mean body weight reduction of 24.2% over 48 weeks -- the largest reduction reported for any obesity drug in a peer-reviewed trial at the time of publication. Phase 3 trials are currently underway, with results expected in 2025-2026.
How the Triple Receptor Mechanism Works
Reduces appetite and slows gastric emptying. The same target as semaglutide and liraglutide. Well-established in obesity and diabetes treatment.
Enhances insulin sensitivity and may improve fat metabolism. Also targeted by tirzepatide. Emerging evidence suggests synergy with GLP-1 activation.
Increases energy expenditure and promotes fat oxidation. This is the unique third target that distinguishes retatrutide from existing treatments.
Dosing Used in Clinical Trials
The following dose levels were used in the Phase 2 trial (NEJM, 2023). This is trial protocol information, not prescribing guidance.
| Dose Group | Weekly Dose | Escalation | Mean Weight Change at 48 Weeks |
|---|---|---|---|
| Low | 1 mg | No escalation | -8.7% |
| Medium | 4 mg | Start 2 mg, escalate at week 4 | -17.5% |
| Medium-High | 8 mg | Start 2 mg, escalate every 4 weeks | -22.8% |
| High | 12 mg | Start 2 mg, escalate every 4 weeks | -24.2% |
| Placebo | -- | -- | -2.1% |

How Retatrutide Compares
Comparison based on published Phase 2/3 trial data. Direct comparison is limited as these were separate studies with different populations.
| Feature | Retatrutide | Tirzepatide | Semaglutide |
|---|---|---|---|
| Receptors Targeted | GLP-1, GIP, Glucagon | GLP-1, GIP | GLP-1 only |
| Max Weight Loss (Trial) | -24.2% | -22.5% | -16.9% |
| Administration | Once weekly SC | Once weekly SC | Once weekly SC |
| Regulatory Status (SA) | Not approved by SAHPRA | SAHPRA review pending | SAHPRA approved (Wegovy) |
| Trial Phase | Phase 3 (ongoing) | Approved (some markets) | Approved (some markets) |
Data from separate trials with different protocols. Cross-trial comparisons have inherent limitations.
