I've come across posts from folks discussing ongoing trials, and a fair number of members say they're taking 25-30mg or more.
As for me, I've stayed at 15mg for a good while now, but since I've hit my goal, I won't be increasing.
Here's additional information about the trials currently underway:
For tirzepatide (Mounjaro and Zepbound), the maintenance doses that the FDA has approved top out at 15 mg per week. Trials are currently running that look directly at the
25 mg dose as a higher-tier choice (together with a 20 mg dose), assessing how well it works and how safe it is for those who respond more slowly. [

Important Points About the 25 mg Tirzepatide Trial
- Clinical Trial ID: NCT06037252
- Sponsor: Eli Lilly and Company
- Target Audience: Adults living with both obesity and Type 2 diabetes.
- Study Goal: This trial is set up specifically to examine the safety, tolerability, and efficacy of investigational higher doses (20 mg and 25 mg). It seeks to find out whether moving up to these amounts delivers better glycemic control and faster weight loss for patients who get only limited results from the 15 mg maximum. [1, 2, 3, 4]
I went through every one of those reference links pretty carefully, trying to track down where the doses you listed came from, since I'd looked for that same info before without success. The only thing I could turn up regarding doses was an OTP blog post citing "sources" and stating those were the doses. It could be accurate — studying 20-25mg would make sense — but it isn't a definitive source the way Lilly, a paper, or a trial would be. As for the trial info, it says nothing at all about which doses were used.
Somewhere I came across mention that patent filings exist for 20mg and 25 mg strengths. That's what Gemini told me, though I haven't gone through the citations myself. Hallucinations do happen.
Indeed, Eli Lilly has submitted patent applications that zero in on higher concentrations and doses of tirzepatide (the active ingredient behind Mounjaro and Zepbound).
The main international application covering this is
WO2024006662A1 (named
"Tirzepatide Compositions and Use"), published early in 2024.
What the filings show about Eli Lilly's preparations for higher-dose versions:
- Higher Concentration: The currently approved ceiling for tirzepatide sits at 15 mg (given as a 0.5 mL injection, a concentration of 30 mg/mL), yet the application lays explicit claim to stable, pharmaceutically acceptable compositions holding more than 30 mg/mL, up to 60 mg/mL of tirzepatide.
- Named Dosing Strengths: Concentrations spelled out in the filing include 40 mg/mL, 50 mg/mL, 55 mg/mL, and 60 mg/mL. At the usual 0.5 mL injection volume, 40 mg/mL through 60 mg/mL would mean larger total doses, for example 20 mg, 25 mg, or 30 mg.
- Stated Purpose: According to the application, a substantial number of patients need "additional weight management benefit" past the approved 15 mg ceiling. Its focus is the chemical stability required to keep these more concentrated peptides shelf-stable for at least 6 months, while also handling the gastrointestinal side effects that come with higher doses.
With these patents in hand, Eli Lilly is building the legal and regulatory foundation to one day roll out stronger Mounjaro and Zepbound versions, should clinical trials demonstrate that higher doses deliver better weight loss or glycemic control without unacceptable safety issues.
