Informal Self-Check — Not a Diagnostic Tool

How you've been feeling lately.

This is an original, informal self-check covering symptom areas commonly discussed in connection with low testosterone — energy, mood, strength, sleep, and more. It is not a validated clinical screening instrument (like the ADAM questionnaire used in some clinics), has no established sensitivity or specificity, and cannot diagnose anything. Its only purpose is to help you organize your own observations before a conversation with a clinician.

How to Use This Self-Check

Rate honestly, then treat the result as a conversation starter — not an answer.

Rate each itemFor each area, choose the option that best reflects how things have generally felt over the past several weeks — not just today.
Review your summaryYou'll see which areas you flagged as noticeably changed, organized simply — not scored against any clinical threshold.
Bring it to a real conversationUse your answers as a starting point when talking to a doctor — mention which specific areas feel different and for how long, rather than relying on a self-check result alone.
Get an actual test if you're concernedThe only way to know if testosterone is actually low is a blood test — ideally a morning total testosterone, repeated if borderline, alongside SHBG. See the Free Testosterone Calculator once you have those results.

What This Is (and Isn't)

Full transparency about what this tool actually is, since "testosterone quizzes" online often overstate their own reliability.

This is an original questionnaire, not the ADAM questionnaire. The Androgen Deficiency in Aging Males (ADAM) questionnaire is a specific, copyrighted, validated 10-question clinical screening instrument developed at Saint Louis University (Morley et al., 2000). This tool asks different, original questions covering broadly similar symptom areas — it does not reproduce ADAM's questions and makes no claim to its validation, sensitivity, or specificity. Morley JE, Charlton E, Patrick P, et al. "Validation of a screening questionnaire for androgen deficiency in aging males." Metabolism. 2000;49:1239-1242.
It has no established accuracy. Unlike a validated clinical instrument, this self-check has never been tested against blood testosterone levels in a research study — there's no sensitivity, specificity, or scoring threshold behind it, because none has been established. —
Symptoms it asks about are non-specific. Fatigue, low mood, reduced libido, and reduced strength are associated with many conditions besides low testosterone — thyroid disorders, depression, sleep apnea, and simple life stress can all produce a similar symptom pattern. General clinical knowledge; differential diagnosis is a core part of any real evaluation.
The only way to know your testosterone level is a blood test. A self-reported symptom pattern, however carefully rated, cannot substitute for measuring actual testosterone in blood — ideally total testosterone drawn in the morning (when levels are naturally highest), repeated on a second occasion if the first result is low or borderline. Endocrine Society Clinical Practice Guideline for testosterone therapy in men with hypogonadism.

Estimate only — not medical advice. This self-check is not a diagnostic tool, is not validated, and cannot tell you whether your testosterone is actually low. Many conditions unrelated to testosterone can cause similar symptoms. If you're concerned about how you've been feeling, the right next step is a conversation with a doctor and, if appropriate, an actual blood test — not a symptom quiz.

Frequently Asked Questions

Is this the same as the ADAM questionnaire I've seen elsewhere?

No. ADAM is a specific, copyrighted, validated 10-question clinical instrument developed at Saint Louis University. This is a different, original set of questions covering broadly similar territory, written specifically for this page — it makes no claim to being validated or to matching ADAM's studied accuracy.

Can this tell me if I have low testosterone?

No. Nothing about symptoms alone — from this or any questionnaire — can tell you your actual testosterone level. The symptoms asked about here are also associated with many other conditions. Only a blood test can measure testosterone directly.

Why does this matter — isn't a symptom checklist better than nothing?

A checklist can be a useful way to organize your own observations before talking to a doctor, which is exactly how this tool is intended to be used. The risk is treating an unvalidated self-check as if it were a real screening result, which could lead someone to over- or under-estimate a possible issue.

What symptoms are actually associated with low testosterone?

Commonly discussed symptoms include reduced energy, lower libido, reduced muscle strength, mood changes, and sleep disturbance — but all of these are non-specific and can have many other causes, which is exactly why blood testing (not symptoms alone) is how low testosterone is actually identified.

What blood tests should I ask for?

A morning total testosterone is the standard starting point, since levels are naturally highest then and vary through the day. If it's low or borderline, a repeat test and SHBG are often added — SHBG lets you (or your doctor) calculate free testosterone, which the Free Testosterone Calculator on this site can help with once you have those numbers.

I flagged several areas as changed — does that mean I have low T?

Not necessarily. It means those are areas worth specifically mentioning to a doctor, alongside how long they've been going on and anything else going on in your life (sleep, stress, other health changes) that could also explain them.

Why do you mention the ADAM questionnaire's copyright specifically?

Because it's a real, validated clinical instrument that's frequently reproduced online without attribution or licensing. We chose to write original questions rather than reproduce someone else's copyrighted, validated tool without permission — and we think it's worth being upfront about that distinction rather than quietly presenting an unlicensed copy as if it were the real thing.

Does this tool save my answers anywhere?

No — everything runs locally in your browser and nothing is stored, logged, or transmitted. To track your wellness markers over time as part of an actual protocol, see the full Peptide Plug app, which has a dedicated wellness check-in feature.
