Track AHK‑Cu in Peptimes™
AHK-Cu is (alanyl-histidyl-lysine)copper(II): the tripeptide L-alanyl-L-histidyl-L-lysine (Ala-His-Lys) bound to copper. NLM's MeSH lists it under that name and as AHK-Cu. (Source: NLM MeSH.)
Is AHK-Cu FDA-approved?
No. AHK-Cu isn't FDA-approved, and Drugs@FDA lists no application with it as an active ingredient.

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 animals or the lab
A lab study: AHK-Cu lengthened isolated human hair follicles and increased the growth of dermal papilla cells in culture. Its effect on the number of dying cells wasn't statistically significant. Cell and tissue data only, with no animals or people.

How to track it in Peptimes
Add AHK-Cu 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: topical or subcutaneous. Choose the one that matches each dose.
- Logging: the amount you used, 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. Topical 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 AHK-Cu or any other compound.
