Why Choose Single Pen Orders

Single pens are perfect if you're new to GP weight loss injections and want to try one dose first. They're also ideal for patients who know their optimal dose and prefer ordering monthly. Each pen provides exactly four weekly injections of prescription-only tirzepatide, designed to support weight management alongside your reduced-calorie diet and increased physical activity.

Our clinical team can help determine the right starting dose during your online consultation. Most patients begin with 2.5mg and gradually increase based on tolerance and results.

Fast Clinical Assessment & Approval

All GP weight loss injection orders require clinical assessment by our qualified UK prescribers. Our standard approval takes 3 working days, but urgent orders can be processed within 24 hours with our express service upgrade.

The online consultation covers your medical history, current medications, and weight management goals. This ensures tirzepatide injections are suitable and safe for your individual circumstances. Our prescribers are experienced in obesity medicine and licensed to prescribe these specialist treatments.

How Mounjaro Works

These prescription-only weight loss injections contain tirzepatide, which activates two natural hormones - GIP and GLP-1. This dual action may help regulate appetite and promote feelings of fullness after eating. Many patients report reduced food cravings and better portion control when using tirzepatide alongside lifestyle changes.

Each pen contains a month's supply of pre-filled injections. The medication is administered once weekly using the simple pen device. Full injection training and support materials are provided with every order.
