Tracking your TRT bloodwork
Last reviewed 2026-09-28 · 4 min read
If you are on testosterone therapy, your clinician decides which tests you need, when to draw them, and what the results mean. What you can do is keep every result in one place, with the context your clinician will ask about.
What your clinician may check
Which tests, and how often, is your clinician's call. For reference, the FDA-approved label for testosterone cypionate says, in its laboratory tests section, that "Hemoglobin and hematocrit levels (to detect polycythemia) should be checked periodically in patients receiving long-term androgen administration," and notes that "Serum cholesterol may increase during androgen therapy" (DailyMed: Depo-Testosterone label). Your clinician may order other markers too. This page does not list ranges or targets: every lab prints its own reference range, and what a number means for you is a conversation with your clinician.
What to write down for every result
- The marker exactly as the lab names it
- The value and unit (ng/dL and nmol/L are different scales)
- The lab's reference range as printed on the report
- The date and time of the draw
- When your last dose was — context your clinician may ask for
- Anything else your clinician asked you to note
Why the date of your last dose matters
Levels of an injected compound change over the days between doses, so a result means more to your clinician when they know where in that cycle it was drawn. When to draw is their instruction, not a rule from a website.
How Stack helps
- Bloodwork log: add each result with its date and the lab's range; see each marker's history over time.
- Dose log: every dose you take, with its time — so "when was your last dose?" has an answer.
- The report: one PDF with your dose history and your lab results for any date range, to take to an appointment.
Stack logs and organises. It does not tell you whether a result is good or bad, and it never suggests a dose. See the testosterone cypionate and testosterone enanthate library pages, or model what's still in your system with the half-life visualiser.
Questions
What range should my testosterone be in?
That is a question for your clinician. Labs print their own reference ranges, and what a result means depends on you, your treatment and your history.
Which tests do I need?
Your clinician decides. The testosterone cypionate label, for example, says hemoglobin and hematocrit should be checked periodically on long-term therapy.
Can Stack tell me if a result is too high?
No. Stack records your results and the lab's range so you can see them over time and share them. Interpreting them is your clinician's job.
How do I share my results?
Export Stack's report as a PDF for any date range and bring it, or send it, to your appointment.
