Practical guide

Turning months of tracking into ten useful minutes

Review appointments are short. Most of the value comes from being able to answer a handful of predictable questions precisely rather than approximately — and those answers come straight out of a record, if you have one shaped the right way.

The questions you will almost certainly be asked

Across GLP-1, TRT and HRT reviews, the same questions recur. Being able to answer them in seconds changes what the rest of the appointment can cover.

What to bring

A dated dose history

The single most useful thing. Not a summary — the actual dates, with steps and any gaps visible. It answers the first two questions immediately and gives context for everything else. Peptide Plug Pro exports this as JSON or CSV; a written list works fine too.

Your labs, with timing

Results are more interpretable when the clinician can see when the sample was taken relative to your last dose. For injectable protocols especially, a level drawn at trough and one drawn near peak are very different numbers, and a result without that context is much harder to use.

A short written list of questions

Write it before you go. The reason "any questions?" gets answered with "no" is not that people have none — it is that appointments are compressed and questions evaporate. A list on your phone solves it entirely.

Specifics rather than impressions

"It has been a bit up and down" is hard to act on. "I felt fine for the first four days after each injection and noticeably flat on days six and seven, for about the last six weeks" is a description a clinician can actually work with. That level of specificity is only available from notes taken at the time.

What not to bring

A simple preparation routine

  1. A week before: check whether any labs need doing beforehand, and book them with enough lead time for results to arrive.
  2. A few days before: read back over your log and note anything that stands out. Patterns are easier to see in review than in the moment.
  3. The day before: write your questions down. Three is plenty.
  4. On the day: bring the dose history, the labs with their timing, and the questions.
  5. Immediately after: write down what was decided, while you still remember it accurately. This becomes the anchor for the next review.

That last step is the one most often skipped and most often regretted. What was agreed at an appointment is exactly the thing that becomes fuzzy three months later.

Frequently asked

What is the most useful thing to bring?
A dated dose history showing what you took and when, including gaps. It answers the first questions immediately and gives context to everything else in the appointment.
Should I bring all my data?
Bring a summary and have the detail available if asked. Nobody reads a hundred pages of raw entries in a short appointment, and burying the signal makes the record less useful, not more.
Does the timing of my lab test matter?
Often substantially, particularly for injectable protocols where levels vary across an interval. Note when the sample was taken relative to your last dose — a result without that context is much harder to interpret.
What should I do straight after the appointment?
Write down what was decided while you still remember it precisely. It becomes the reference point for the next review, and it is the detail that fades fastest.
Can I export my history from Peptide Plug?
Yes. Pro accounts export the full history as JSON or CSV, which most people find easier to bring than a verbal summary.
