Works on two gut hormones at once, GLP-1 and GIP. In trials it led to some of the biggest weight losses seen with an approved medicine.
Approved in the US, EU and other countries. Mounjaro treats type 2 diabetes (and, in the EU, is also used for weight management). Zepbound is approved in the US for weight management and for sleep apnea in adults with obesity.
Tirzepatide is a single molecule that acts like two hormones your gut releases after meals: GLP-1 and GIP. Both help control appetite and blood sugar.
Like semaglutide, it tells your brain you’re full, slows your stomach and helps insulin release when blood sugar is high. Adding the GIP signal appears to strengthen these effects.

Follow the manufacturer's batch-specific storage temperature and conditions.
Keep in original packaging, away from direct sunlight and excess heat.
Refer to the lot-specific expiry date and stability documentation. Shelf life should not be inferred from the product name alone.
For solvent compatibility or preparation specifications, request the manufacturer’s batch documentation. Research protocols should be established by qualified laboratory personnel.
Every product comes three ways. It's the same peptide and the same amounts; what changes is the packaging, what's included and the price. Start with the pen kit box, which has the reusable pen, then refill it with dual-chamber vials.

The freeze-dried peptide and the bacteriostatic (BAC) water sit in separate chambers, divided by a rubber stopper. They stay apart until the cartridge is used.
The pen kit box has the reusable pen body with a dual-chamber vial, 12 disposable needles and a booklet. The drive, dial and indicator window stay with the pen: when a cartridge is empty, fit a new dual-chamber vial.
Choose the vial if you already have bacteriostatic water and your own lab supplies. It's the lowest price for the same amount.

Mounjaro, Zepbound
Works on two gut hormones at once, GLP-1 and GIP. In trials it led to some of the biggest weight losses seen with an approved medicine.
StudyWeight management
The experimental peptide combines GLP-1, GIP, amylin and calcitonin activity. Here is what the original research can tell us about weight loss.
StudyWeight management
A small MRI analysis found a 12% reduction in visceral-fat volume, not body weight. A possible effect on weight regain after GLP-1 medicines is still an animal finding.
StudyWeight management
New phase 3 results show strong weight loss in people with type 2 diabetes or heart disease. Lilly plans to apply for US approval by early 2027.
