"I’d tried every diet going for thirty years and nothing ever stuck. With Bloomwell the weight came off steadily — and for the first time in my life, it’s stayed off. I feel like myself again."

Andy Smith before and after weight loss with Bloomwell
"I was sceptical — I’m not someone who does health kicks. But the plan was simple, the coaching kept me honest, and 19 kg later even my knees have stopped complaining. Best decision I’ve made in years."

What is Mounjaro?
Mounjaro (tirzepatide) is a once-weekly injectable medicine, approved in the UK by the MHRA for weight management as well as type 2 diabetes. You take it once a week using a pre-filled pen.
How does tirzepatide work?
Tirzepatide works similarly to other GLP-1 medications, however, tirzepatide differs from the other medications in that it is a dual-action GLP-1 (short for glucagon-like peptide 1) and GIP (short for glucose-dependent insulinotropic polypeptide) medication. This means that it works by mimicking the action of both the GLP-1 and GIP hormones, which help regulate your metabolism. In doing so, tirzepatide makes you feel fuller faster and for longer. It also communicates with the part of your brain in charge of hunger and satiety, helping you regulate how much you eat. When combined with an appropriate diet and exercise, this makes tirzepatide an effective treatment for weight loss.
How do you take tirzepatide?
Tirzepatide is a once-weekly injection that comes in a pre-filled, single-dose pen. If prescribed, you’ll receive detailed instructions from your Bloomwell support team on how to inject it in your stomach, arm, or thigh.
