Mounjaro Pen Vs 40mg Tirzepatide Vial
Tirzepatide 40mg Vials – Unmatched Value
Save up to 75% compared to pens
One 40 mg vial = 8 weeks supply
Easy to use—guide included
Stop overpaying for less. Our 40mg Tirzepatide vials are just £119, or grab the full kit with everything you need for only £129.99—a fraction of the cost of branded Mounjaro pens. The exact same ingredients are in the vial (once mixed) as the Pen, Bacteriostatic water, and Tirzepatide
Cost Comparison:
Mounjaro 2.5mg pen: ~£120 (4 shots, 4 weeks)
Mounjaro 5mg pen: ~£140 (4 shots, 4 weeks)
Tirzepatide 40mg vial: Covers weeks 1 to 4 at 2.5mg and weeks 5 to 8 at 5mg, and you still have 10mg left over for another 2 weeks at 5mg for nearly the same price!
That's 10 weeks for £119.99 when using the vials instead of the pens, which only last 4 weeks for the same cost
Why pay more for just one month when a single vial gives you more than double the time?
Pens might feel convenient, but vials are just as easy—especially with the simple step-by-step guide. Once you try them, you’ll see why everyone is switching: more value, more flexibility, and the same ease of use.
Even if you are on the Mounjaro 7.5mg Pens, you still save. The 40mg Vial will last you 5 weeks, giving you an extra week and costing roughly £40 less.
Bottom Line: Vials deliver more than 8 weeks for the cost of a 4-week pen. Smart choice. Better value.
