What else the video covers
She describes the cost and side effects as she experienced them. The pharmacy quoted about $1,149 a month because insurance did not cover it, but she says a coupon from the Mounjaro website brought it to $25 a month and can be used 12 times. Over the week she reports one evening of nausea, a slight headache on injection day, eye twitching she attributes to Phentermine, and some constipation. She says she had almost no appetite, which she credits mainly to Phentermine, and had to push herself to eat over 1,000 calories a day.
She says she lost 9 pounds in the first week, more than she has lost on anything before, and feels energized. She plans to switch to her thigh for the next injection because her stomach has little fat after a tummy tuck. According to the video, her doctor plans 2.5 milligrams for the first month, then 5 milligrams, then 7.5 milligrams. She ends by saying she will aim for 5 pounds in week two.

Our guides closest to what this video covers, with prices checked weekly.
- 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 dosage chart: the label's schedule, every pen and vial, and what each dose costs
Mounjaro starts at 2.5 mg injected once a week. If more blood sugar control is needed, the dose goes up in 2.5 mg steps after at least four weeks on the current dose, to a maximum of 15 mg a week for adults and 10 mg for children 10 and older. Lilly sells every strength self-pay starting at $499 a month, so on the brand the price does not climb with the dose.
- 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.
