Mason Newman used Mounjaro to lose 12 stone, dropping from size XXXL to size S. He said the drug brought an unexpected physical change. The GLP-1 drug is also known as a diabetes treatment. Similar drugs include Ozempic and Wegovy.
Mounjaro reduces appetite and can cause major weight loss. Doctors previously said reported growth can result from fat loss around the groin. Newman said he also stopped heavy takeaway eating. He said his business success increased during this period.
In the UK, Mounjaro is available through the NHS under strict rules. Online pharmacies have expanded access beyond those limits. Studies suggest benefits like lower cholesterol, blood pressure, and dementia risk. The drugs can also cause unpleasant side effects.
Newman spoke to The Sun about his experience.
“I tried the keto diet, water fasting. I tried juices. I tried eating nothing but two chicken breasts a day and nothing else.
“That lasted three weeks and was more of a mental challenge than anything. I couldn’t stick to them.
“I saw Oprah and people like that started taking it… then rumours about the Kardashians.
“I sat on it for about a month and just thought, ‘F*** it. Why not try it? It felt like a cheat code – an easy way to lose weight at the time.”
Now, Newman weighs 11 stone and takes 15mg injections. He said stopping the drug caused weight gain and anxiety.
“The first thing I noticed was I grew three inches on my penis,” he laughs. “Because when the fat goes you actually do see more of yourself.”
