I took Mounjaro for 3 months - the results were astounding.
Patient story
Our summary
Gordon, who runs the FatOldClimber channel, reviews his first three months on Mounjaro. He says he had tried many diets over more than 10 years, including intermittent fasting and the carnivore diet, and lost weight each time but could not sustain it. His highest weight, during the pandemic, was 323 pounds (146 kilos). He chose Mounjaro over Ozempic because he says much of the research he read suggests it has a greater effect on weight loss, and he ordered it from a UK supplier because it is not available to him on the NHS.

What else the video covers
He says the effect on his thinking about food was almost immediate. After the first 2.5 mg injection he stopped thinking about snacks, and he reports that he has not snacked at all in three months apart from a few social occasions. He lost nine pounds in week one and seven in week two. Over three months he reports losing 45 pounds (20 kilos, about 15% of his body weight) and seven and a half inches (19 cm) from his waist. Side effects were limited, according to him, to a dry mouth on injection days and some constipation after a dose increase. He moved from 2.5 mg to 5 mg to 7.5 mg, and describes using an insulin pen to draw a fifth dose from each pen and planning to take a reduced dose from a higher-strength pen.
He says the biggest payoff has been in climbing: he sent his first V4 (6B) and reports less knee pain, lower blood pressure and no more ankle swelling. He plans to continue for another three months at 7.5 mg and to wean off later. He stresses that results vary and that viewers should do their own research.

- Mounjaro for weight loss, and why Zepbound exists
Mounjaro is tirzepatide approved for type 2 diabetes. Zepbound is the same molecule from the same maker, approved for weight management, and it goes to the same 15 mg. So unlike Ozempic and Wegovy, there is no dose ceiling pushing you from one to the other: the reason people move is coverage and cash price, not strength. Using Mounjaro for weight is off-label and a prescriber's decision. In the one head-to-head trial, tirzepatide beat semaglutide, 20.2% mean body-weight loss at 72 weeks against 13.7%.
- Mounjaro vs Ozempic, and the trial everyone quotes about it
Mounjaro is tirzepatide and Ozempic is semaglutide: different molecules, not two brands of the same drug. Both are approved for type 2 diabetes, and the weight-loss versions are Zepbound and Wegovy. In the one head-to-head trial, SURMOUNT-5, tirzepatide produced 20.2% mean body-weight loss at 72 weeks against semaglutide's 13.7%. The detail almost every page omits: that trial dosed semaglutide to 2.4 mg in people without diabetes, which is the Wegovy range. Ozempic tops out at 2 mg. The famous result did not test Ozempic's dose range.
- Mounjaro side effects: the label's numbers by dose, the low blood sugar risk, and how tirzepatide compares at weight-loss doses
On Mounjaro's own label, the common side effects are stomach ones and they rise with the dose: nausea in 12, 15 and 18 percent of people at 5, 10 and 15 mg against 4 percent on placebo, diarrhea 12 to 17 against 9, and any gastrointestinal reaction in 37 to 44 percent against 20. Most of it happens while the dose is being raised and fades. Low blood sugar is rare on Mounjaro alone and is mainly a risk when it is added to insulin or a sulfonylurea. Below: the full table, the rare warnings, and why Zepbound's numbers for the same molecule look higher.
