Choose Your Single Pen Dosage Strength

Single Pen Pricing - All Dosage Strengths Available

Our single pen options provide flexibility for customers who prefer to purchase one month's supply at a time. Each pen delivers four weekly injections of prescription-only tirzepatide, designed to support your weight management journey alongside lifestyle changes.

Current single pen pricing: 2.5mg starter dose from £129.99 (first order price), progressing through 5mg (£159.99 first order), 7.5mg (£209.99 first order), 10mg (£229.99 first order), 12.5mg (£259.99 first order), up to the maximum 15mg dose (£278.99 first order). All first-time customers save £40 with code FIRST40.

Why Choose Single Pen Purchase?

Single pen ordering suits customers who want to trial the treatment, prefer monthly purchasing, or are transitioning between dosage strengths. Each pen provides exactly four weeks of treatment with no wastage. Your healthcare professional will determine the appropriate starting dose during your clinical assessment, typically beginning with 2.5mg and increasing gradually as tolerance develops.

Returning customers receive ongoing discounts with £25 off every subsequent order. This makes regular single pen purchases cost-effective for long-term treatment plans while maintaining purchasing flexibility.

Prescription-Only Treatment Process

Mounjaro requires prescription-only access through clinical assessment by our UK-qualified prescribers. The online consultation covers your medical history, current medications, and weight management goals to ensure suitability. Our GPhC-registered pharmacy then dispenses your single pen with complete treatment guidance.

Standard approval takes 3 working days, with express 24-hour processing available as a paid upgrade for urgent orders. Each single pen ships with injection instructions, storage guidelines, and ongoing support access.

Clinical Support and Monitoring

Single pen purchases include the same clinical support as bundle orders. Our prescribers provide dosage adjustment guidance, side effect management, and progress monitoring throughout your treatment. This prescription-only medicine requires ongoing medical supervision, which we provide through our online platform.

As Mounjaro carries MHRA additional monitoring status (Black Triangle ▼), we maintain detailed treatment records and provide comprehensive patient support for all single pen orders.
