How Does Tirzepatide Work?
Tirzepatide is a dual GIP/GLP-1 receptor agonist — the most advanced single-molecule weight loss injection available today. By targeting two separate hormone pathways simultaneously, it delivers superior fat loss results compared to GLP-1-only options like Semaglutide (Ozempic®/Wegovy®).
The SURMOUNT-1 clinical trial — the largest weight loss trial ever conducted — reported average weight reductions of up to 22.5% of body weight in participants using Tirzepatide. That's significantly more than Semaglutide's 15%.
-
GLP-1 pathway: Suppresses appetite, slows gastric emptying, reduces calorie intake
-
GIP pathway: Enhances fat metabolism, improves insulin sensitivity, amplifies weight loss
-
Once-weekly injection: Simple subcutaneous injection, same as Mounjaro®
-
Outperforms Semaglutide: 22.5% vs 15% average weight loss in clinical trials

Tirzepatide vs Mounjaro® UK — What's the Difference?
The short answer: there is no difference in the active ingredient. Mounjaro® is simply the brand name for Tirzepatide, manufactured by Eli Lilly. When you buy Mounjaro® from a UK clinic or pharmacy, you are paying for the brand name, the pre-filled pen device, the prescription process, and the clinic's margin — not for a superior molecule.
Slim Shots supplies Tirzepatide — the same active ingredient — lab-verified to pharmaceutical-grade purity, at a fraction of the Mounjaro® price. No prescription. No clinic. No waiting list. Just the most effective dual-agonist weight loss injection available in the UK, delivered discreetly to your door.
Is Tirzepatide Better Than Semaglutide?
Clinical data consistently shows Tirzepatide outperforms Semaglutide for weight loss. The SURMOUNT-1 trial reported average weight reductions of up to 22.5% with Tirzepatide, compared to approximately 15% with Semaglutide (Ozempic®/Wegovy®). That's roughly 50% more weight loss from the same once-weekly injection schedule.
If you've tried Semaglutide and want stronger results — or if you're starting your weight loss injection journey and want the most effective option — Tirzepatide from Slim Shots is the clear choice.
Want Even More Powerful Results? Try Retatrutide.
If Tirzepatide is the current gold standard, Retatrutide is the next generation. As a triple GLP-1/GIP/glucagon receptor agonist, Retatrutide has shown average weight reductions exceeding 24% in Phase 2 clinical trials — surpassing even Tirzepatide. It's not yet available as a branded medicine, but it's available now at Slim Shots.
