Choose Your Injection
Pick a spot on your stomach, thigh, or upper arm. Rotate between areas each week to avoid irritation.

Inject Your Dose
Pinch the skin, insert the needle at a 90° angle, and press the button. Hold for 10 seconds to ensure the full dose is delivered.

Frequently Asked Questions
Find answers to common questions about our products, shipping, returns, and more.
What is retatrutide and how does it work?
+
Retatrutide is a next-generation GLP-1 that targets three receptors in your body to suppress appetite, burn fat, and regulate blood sugar. It's the most advanced weight loss compound available, outperforming single-receptor alternatives like Ozempic and Mounjaro.
How much weight can I expect to lose?
+
Clinical trials showed an average of 24% body weight loss. Most of our customers see visible results within 2-3 weeks of starting, with the majority reaching their goal weight on a single pen.
How do I use the pen?
+
The pen comes pre-filled and ready to use — no mixing or preparation needed. Simply dial your dose, inject into your stomach, thigh, or upper arm once a week, and you're done. Full instructions are included with every order.
What dose should I start on?
+
Start at 2.5mg per week for the first few weeks, then increase to 5mg as your body adjusts. Most people achieve their results without needing to go higher than 5mg.
Are there any side effects?
+
The most common side effects are mild nausea and reduced appetite in the first 1-2 weeks. These typically settle as your body adjusts to the medication. Starting on a low dose minimises this.
How long does shipping take?
+
Orders are dispatched within 24 hours and delivered via tracked next-day delivery.
How should I store my pen?
+
Keep your pen refrigerated between 2-8°C. Do not freeze. Once in use, the pen can be kept at room temperature for up to 28 days.
Is one pen enough?
+
For the vast majority of customers, yes. The 40mg pen contains more than enough for a full cycle — most people use 20-30mg total before reaching their desired weight.
