What studies have looked at
Each point says who or what was studied and what the study reported, with its source and the date we checked it. These are findings from the sources cited, not advice or a promise of any result.
- In humans
A placebo-controlled trial in 299 adults: most physical-performance measures, including grip strength and gait speed, didn't differ from placebo. Small gains appeared only in subgroups (calf raises in people under 40, a step test in men over 40).

- In humans
A randomised placebo-controlled trial in 43 adults with prediabetes or type 2 diabetes: blood glucose was lower at 90 and 120 minutes of a glucose tolerance test with carnosine. Body composition and the other secondary outcomes didn't change.

How to track it in Peptimes
Add carnosine in My Protocols and set the schedule you already follow: days of the week, times of day and a start date. Peptimes never suggests an amount when you log or schedule a dose. Its Library entry shows the status label “Not FDA-Approved”.
- Routes: oral or subcutaneous. Choose the one that matches each dose.
- Logging: the amount you took, the route and how you feel.
- Injection sites: subcutaneous doses record the site, and Insights shows where you’ve injected and how recently. It never suggests where to inject next. Oral doses skip this step.
- Reminders and history: reminders at your times, Dose History, the Calendar and CSV or JSON export work as described on the peptide tracker app page.
Peptimes is a tracking app, not medical advice. Talk to a licensed clinician about your treatment. Peptimes doesn’t sell carnosine or any other compound.
