The Weight Loss Treatment That Makes People Say “I Should Have Started This Sooner” — Now Available in Chertsey
How Mounjaro is changing what’s possible for weight loss patients across Surrey and Kent

You’ve been here before. That moment when you’ve decided something has to change. You’ve tried the diets, downloaded the apps, maybe even paid for a personal trainer. Nothing stuck. Or it worked for a while, then stopped working.
This time feels different because something fundamental has changed in how weight loss treatment actually works.
Mounjaro (tirzepatide) exists. And it’s available in Ashford without a GP referral, no waiting list, through Easy Pharmacy.
This isn’t a meal plan. It’s not willpower repackaged. It’s prescription medication that works on the biology of hunger directly. In Eli Lilly’s SURMOUNT-1 clinical trial, people lost an average of 20.9% of their body weight over 72 weeks on the 15mg dose. Not through deprivation. Through a medication that changes how your brain receives hunger signals.
Most patients who start Mounjaro at Easy Pharmacy say the same thing a few weeks in: they waited too long.
What Makes Mounjaro Different From Everything Else You’ve Tried
The weight loss industry has spent decades selling effort as the solution. Mounjaro works differently because it addresses what makes weight loss so difficult in the first place: your body’s biological resistance to losing weight.
When you restrict calories, your body fights back. Hunger hormones increase. Metabolism slows. The signals telling your brain “you’re satisfied” get weaker. This isn’t weakness. It’s biology. Your body is trying to protect you from what it perceives as starvation.

Mounjaro is a dual GIP and GLP-1 receptor agonist. That’s medical terminology for a medication that mimics two naturally occurring hormones in your body that regulate appetite, blood sugar, and how full you feel after eating. It doesn’t suppress hunger through stimulants. It changes the signal your brain receives about food.
In practice, this means the constant background noise of hunger starts to fade. The impulse to snack between meals becomes quieter. Portions that used to feel restrictive start feeling satisfying. You’re not fighting your body anymore.

Results shown are estimates based on average outcomes from the SURMOUNT-1 clinical trial (tirzepatide 15 mg, 72-week data). Individual results may vary significantly. Weight loss depends on adherence to treatment, diet, exercise, and individual metabolic factors. This calculator is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional before starting any weight loss treatment.
The Clinical Evidence: What Eli Lilly’s Studies Actually Show
Eli Lilly’s SURMOUNT trials represent the most comprehensive research programme ever conducted on a weight loss medication. Here’s what the data shows:
SURMOUNT-1 studied adults with obesity or who were overweight without diabetes over 72 weeks. Participants on the 15mg dose lost an average of 20.9% of their body weight. For someone starting at 100kg, that’s over 20kg lost. More importantly, 91% of participants on Mounjaro lost at least 5% of their body weight, and 57% lost at least 20%.

SURMOUNT-3 looked at what happens when patients who lost weight through intensive lifestyle intervention continued with Mounjaro versus placebo. Those on Mounjaro lost an additional 21.1% beyond their initial weight reduction, for a total average weight loss of 26.6% from study entry.
In November 2024, Eli Lilly published three-year data from SURMOUNT-1 showing sustained weight loss of 22.9% on the 15mg dose through 176 weeks of treatment. This wasn’t short-term results that disappeared when the medication stopped. This was sustained, meaningful weight reduction maintained over three years.
Perhaps most significantly, the SURMOUNT-5 head-to-head trial compared Mounjaro directly to Wegovy (semaglutide). Mounjaro produced 47% greater relative weight loss — an average of 20.2% compared to 13.7% with Wegovy at 72 weeks.
These aren’t marginal differences. This is a medication that produces weight loss most people have never been able to achieve through diet and exercise alone, sustained over years, not months.
Who Mounjaro Works For (And Who It Doesn’t)
Mounjaro isn’t right for everyone. The NHS criteria for accessing it are extremely tight: a BMI of 40 or above, at least four weight-related health conditions, and access through specialist weight management services being rolled out over twelve years. Most people who would benefit won’t qualify under those guidelines for a long time.

Private prescription through Easy Pharmacy in Ashford uses different criteria. You’re likely eligible if:
- Your BMI is 30 or above, or 27 or above with a weight-related health condition (such as high blood pressure, type 2 diabetes, or sleep apnoea)
- You’ve tried to lose weight through diet and exercise without sustained success
- You don’t have a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2
- You’re not pregnant or breastfeeding
An eligibility check with Easy Pharmacy’s clinical team takes about ten minutes. If you qualify, you’ll have a consultation to discuss whether Mounjaro is the right option for your circumstances, health history, and weight loss goals.
What to Expect: The First 12 Weeks
Week 1-4: The Starting Dose You begin at 2.5mg, injected once weekly. The starting dose is intentionally low to let your body adjust. Some people notice mild nausea or reduced appetite immediately. Most don’t notice much at all. This is normal. The medication is working, but dramatic results aren’t expected yet.
Week 5-8: Dose Increases The dose increases to 5mg, then potentially 7.5mg. This is where appetite suppression becomes more noticeable. The impulse to reach for snacks between meals starts to fade. Portions that used to feel restrictive begin feeling satisfying. Weight loss accelerates.
Week 9-12: Finding Your Maintenance Dose Your clinician will continue adjusting your dose based on how you’re responding and tolerating the medication. Some patients reach their optimal dose at 10mg. Others benefit from titrating up to 15mg. The goal is the highest dose you tolerate well.
Most patients report the same pattern: the first month is about adjustment. The second and third months are when meaningful weight loss becomes visible, not just on the scales but in how clothes fit and how you feel moving through your day.

Side Effects: What You Should Know
The most common side effects are gastrointestinal: nausea, diarrhoea, constipation, and reduced appetite. In Eli Lilly’s trials, these were mostly mild to moderate and occurred primarily during dose escalation. They tend to improve as your body adjusts.
Strategies that help:
- Eat smaller, more frequent meals rather than large portions
- Avoid high-fat and heavily processed foods, especially in the first weeks
- Stay well hydrated
- Allow your body time to adjust before increasing doses
Serious side effects are rare but possible. Mounjaro carries a warning about thyroid tumours, including thyroid cancer, observed in animal studies. It’s not approved for anyone with a personal or family history of medullary thyroid carcinoma or MEN 2 syndrome.
If you experience severe abdominal pain that won’t go away, persistent nausea and vomiting, or symptoms of pancreatitis, contact your clinician immediately.
Your eligibility consultation at Easy Pharmacy covers your full medical history to ensure Mounjaro is safe for you specifically. This isn’t a medication you start without clinical oversight.
