Description
Tirzepatide, known under the brand names Mounjaro and Zepbound, is a medication used for the treatment of type 2 diabetes and for assisting with weight loss in certain individuals. This drug is administered through subcutaneous injections. It functions as a dual agonist for the GLP-1 and GIP receptors, which play roles in controlling blood sugar. By activating these receptors, tirzepatide stimulates insulin release and can lead to improved blood glucose control and potential weight loss when combined with diet and exercise.
The medication was approved in the United States for diabetes treatment in May 2022 and later for weight loss under the name Zepbound in November 2023. The European Union, Canada, and Australia have also approved tirzepatide for diabetes treatment in 2022.
The common side effects of tirzepatide include nausea, vomiting, diarrhea, decreased appetite, constipation, abdominal discomfort, and pain. It’s essential to note that tirzepatide has a boxed warning for the risk of thyroid C-cell tumors, and it should not be used in people with a personal or family history of certain thyroid cancers or Multiple Endocrine Neoplasia syndrome type 2. Moreover, tirzepatide should be used cautiously in patients with a history of pancreas or kidney disease, stomach problems, or diabetic retinopathy.
If you’re prescribed this medication, it’s crucial to follow the specific dietary instructions from your healthcare provider and understand the appropriate use, potential side effects, and storage guidelines. It’s also important to maintain regular appointments with your doctor and to undergo any recommended tests to monitor your body’s response to the medication.

My rat was on 7.5 mg of Tirz and stalled for a few months. I dropped his Tirz to 5 mg and added 2 mg of Reta. Tirz and Reta stacking worked amazing and my rat was able to reach the goal weight in less than 4 months.

I’m using a combination of AOD9604, Reta, and Tirz from Best Peptides for my research. After eight weeks, I’ve observed significant fat loss in my subject, specifically in the abdominal area.
