How Does Semaglutide Work?
Semaglutide is a GLP-1 receptor agonist — it mimics the GLP-1 hormone your body naturally produces after eating. By activating GLP-1 receptors in the brain and gut, it powerfully suppresses appetite, slows gastric emptying, and reduces calorie intake — leading to significant, sustained weight loss.
The STEP-1 clinical trial reported average weight reductions of up to 15% of body weight with Semaglutide — making it one of the most effective weight loss injections ever studied. Ozempic® and Wegovy® are simply brand names for the same molecule.
-
Appetite suppression: Signals the brain to reduce hunger and increase feelings of fullness
-
Slows gastric emptying: Food stays in the stomach longer, reducing overall calorie intake
-
Once-weekly injection: Simple subcutaneous injection, same schedule as Ozempic®/Wegovy®
-
Proven results: Up to 15% average body weight reduction in the STEP-1 trial

Common Questions
Is Semaglutide the same as Ozempic® and Wegovy®?
Yes. Ozempic® and Wegovy® are simply brand names for Semaglutide, manufactured by Novo Nordisk. The active ingredient is identical. Slim Shots supplies Semaglutide — the same molecule — lab-verified to pharmaceutical-grade purity, at a fraction of the branded price.
Do I need a prescription to buy Semaglutide from Slim Shots?
No. You can order Semaglutide directly from our online shop — no prescription, no BMI criteria, no GP referral required. Simply browse our shop and complete your order online.
How much weight can I lose with Semaglutide?
The STEP-1 clinical trial reported average weight reductions of up to 15% of body weight with Semaglutide over 68 weeks. Individual results vary depending on diet, exercise and starting weight. If you want stronger results, our Tirzepatide (up to 22.5%) or Retatrutide (24%+) may be better options — chat with our team on WhatsApp for guidance.
How is Semaglutide stored?
Unmixed vials should be stored in a cool, dark place. Once reconstituted with bacteriostatic water, the solution should be refrigerated at 2–8°C and used within 28 days. Full storage and dosing guidance is available from our support team via WhatsApp.
Semaglutide vs Ozempic® UK — What's the Difference?
The short answer: there is no difference in the active ingredient. Ozempic® and Wegovy® are simply brand names for Semaglutide, manufactured by Novo Nordisk. When you buy Ozempic® 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 Semaglutide — the same active ingredient — lab-verified to pharmaceutical-grade purity, at a fraction of the Ozempic® price. No prescription. No clinic. No waiting list. Just the proven GLP-1 weight loss injection, delivered discreetly to your door.
Should I Choose Semaglutide or Tirzepatide?
Semaglutide is an excellent starting point — proven, well-tolerated, and highly effective with up to 15% average weight loss. However, if you want stronger results, Tirzepatide (the active ingredient in Mounjaro®) delivers up to 22.5% average weight loss by targeting two hormone pathways instead of one.
For the most powerful results available, Retatrutide — a triple GLP-1/GIP/glucagon agonist — has shown 24%+ weight loss in Phase 2 trials. All three are available at Slim Shots with no prescription required.
Why Is Ozempic® So Expensive in the UK?
Ozempic® costs £200–£300+ per month in the UK because you're paying for the Novo Nordisk brand, the pre-filled pen device, the prescription consultation, and the pharmacy or clinic's margin. The active ingredient — Semaglutide — is the same molecule regardless of where it comes from.
Slim Shots removes all of that overhead. You get the same Semaglutide, lab-verified to pharmaceutical-grade purity, delivered discreetly to your door — at a fraction of the Ozempic® price, with no prescription required.
