Peptide Plug
Free Estradiol & HRT Tracker

Patches, gel, tablets: one record.

Hormone therapy rarely stays in one format. People switch from oral to transdermal, change patch strength, add or adjust progesterone, and try a different interval, often several times in the first year. Peptide Plug keeps all of it on a single timeline, so the question “what were we doing in March, and how did it go?” has an answer.

Dose interval projector

Different formats run on very different schedules. Enter yours and see the next few dates. Numbers, dates and choices you enter in this tool are not saved or sent. Page analytics, described on our Privacy page, record page views and clicks but not what you type or select.

What the tracker holds

HRT is a series of adjustments, and the adjustments are the part worth recording.

  1. Dose and formatPatch, gel, spray, tablet or injection, each with its own strength and interval, and a record of when you changed between them.
  2. Progesterone alongside itLogged on the same timeline rather than in a separate note, including cyclical and continuous patterns.
  3. Symptoms over timeOptional daily or weekly entries, so a change in how you feel can be read against when a dose actually changed.
  4. Labs when you have themEstradiol and any other marker you enter, plotted against the dose history rather than kept in a photo roll.

Why format changes are hard to track

Three things that make HRT records go fuzzy.

Tracking tool only, not medical advice. Peptide Plug records what you enter and shows it back to you over time. It does not diagnose anything, does not recommend a dose or a formulation, and is not a substitute for a clinician who knows your history.

Frequently Asked Questions

Does Peptide Plug prescribe or supply hormone therapy?
No. It is a tracking and organisation tool only. We do not prescribe, sell, source or supply anything, and we do not link to vendors.
Can it handle patches, gel and injections in one record?
Yes. Each format carries its own strength and interval, and switching between them is recorded as a dated change rather than a new record. Your earlier history stays intact.
Does it track progesterone as well as estradiol?
Yes. Both sit on the same timeline, including cyclical patterns where progesterone is taken for part of the month rather than continuously.
Can I log symptoms without logging them every day?
Yes. Symptom entries are optional and can be as frequent or infrequent as you like. Some people log weekly, some only around a dose change, and the tracker does not nag about gaps.
Will it tell me whether my dose is right?
No, and it deliberately does not try. It shows you what you recorded and when. Whether a dose or format suits you is a conversation for you and your clinician, and the export exists to make that conversation easier.
Can I bring the record to an appointment?
Yes. Every account can export the full history as JSON, and Pro adds CSV exports of your log, inventory and cost forecast. A dated record of what changed and when is usually more useful than trying to reconstruct a year verbally.
Is this only for menopause and perimenopause?
The tracker records doses, formats, intervals, symptoms and labs. It does not ask why you are taking something, and it works the same regardless. Nothing about your reason for tracking is required or stored.
How is my data handled?
Your entries are stored in your account and encrypted in transit. We don't sell them. They're shared only with the service providers that run the app (listed on the Privacy page), and one administrator can access account data for support. Any account can export a full JSON copy at any time or request a copy, and you can delete your account from Settings; the few records kept after deletion are listed on the Privacy page.
