Progress and charts.

PepCue charts what you logged. That sounds obvious, but it is the single most important thing to hold on to when reading any of these views, because a chart drawn from your own entries is a picture of your record rather than a measurement of your body.

Adherence.

Adherence compares doses logged against doses scheduled over a window, including how close each one landed to its planned time. It is most useful as a sanity check before drawing any conclusion from the other charts: a month at sixty percent adherence cannot support a statement about whether something worked.

Weight and measurements.

Weight is plotted as a trend rather than a sequence of daily readings, because daily weight is dominated by water, food, and timing. If you connect Apple Health, weight and body-composition figures flow in automatically with your permission. Measurements you enter by hand sit on the same timeline.

Symptoms.

Symptoms logged with a severity are broken down by compound and by time. This is the closest the app comes to something useful clinically, and it depends entirely on logging discipline. A symptom recorded on the day, with a severity, is evidence; the same symptom remembered three weeks later is an anecdote.

Estimated levels.

The estimated level curve is a model. It takes your logged doses and a published half-life and draws what the resulting accumulation would look like under textbook assumptions. It is not a blood test, it does not know your metabolism, your body composition, your absorption, or the actual potency of what you injected, and for research compounds the underlying half-life figure is often itself uncertain. Read it as a shape that helps you reason about timing, never as a value.

What charts cannot do.

• •They cannot establish that a compound caused a change you observed
• •They cannot separate a protocol from diet, training, sleep, season, or regression to the mean
• •They cannot substitute for lab work ordered and interpreted by a clinician

The honest use of these charts is as a prepared record to bring to an appointment. They turn a vague account of the last three months into something specific enough to discuss.
