How to track PT-141 in PepLabo

  1. Add PT-141 as you were given it

    PepLabo records any compound you enter yourself. Pick the form (pen, vial, tablets or other); the library entry shows its current status, with sources.

  2. Schedule it, or not

    Set a schedule with reminders, or choose No reminder and log each use when it happens. Every entry keeps the date and time.

  3. Log every dose

    Each log saves the date, time and the amount you entered. For vials the calculator converts it to U-100 units; pens and tablets need no unit math.

  4. Rotate injection sites

    Tap where the injection went on a front and back body map. The last site shows on the Today screen, and a weekly heat map shows which areas rested. When you log a dose, it suggests the area you have rested longest among the ones you use, and you can always pick another.

  5. Note how you feel

    A quick check-in records energy, sleep, mood and symptoms such as nausea or an injection-site reaction. You can link it to a dose from the 72 hours before; the app draws no conclusions.

  6. Keep a history you can share

    Every dose stays in your history. Export it as a file or create a PDF report (Pro) to show your clinician.

Questions

Can I log PT-141 only when I use it, without a schedule?

Yes. Set the schedule to No reminder and log each use when it happens. Every entry keeps the time and site, and you can add a check-in on how you felt.

Is PT-141 from a research supplier the same as Vyleesi®?

Vyleesi® is an FDA-approved product made to a specified quality. Products sold as “PT-141” for research are not approved medicines, and PepLabo cannot verify what they contain. The app records whatever you enter.

Does PepLabo tell me what PT-141 dose to take?

No. The amount, the timing and the treatment are decided by you and your prescriber; PepLabo writes down what was decided and reminds you when it is due.
