How sleep, alcohol, training and stress actually move the numbers men care about. Written to inform, not to scare. Education, never diagnosis.
A drink or two now and then does very little to your baseline. Heavy or regular drinking does, and that effect is real and measurable.
In one controlled study, a week of short sleep lowered daytime testosterone in healthy young men by 10 to 15 percent. That is what a decade of ageing does.
A hard session gives you a real spike for about an hour. The part nobody sells you: it does very little to your everyday baseline.
Cortisol and testosterone pull in opposite directions. It is the input men miss most, because there is nothing to point at the next morning.
After 30, testosterone drifts down by roughly one percent a year. Real, but slow. A sharp change does not add up to age on its own.
No. Stamnr is a tracking and education tool. The Climb does not diagnose, treat or predict any condition. It helps you see how four daily inputs, sleep, alcohol, training and stress, move together over time. For anything clinical, speak to a doctor.
No app can read your hormones from your phone, and Stamnr does not claim to. Stamnr tracks the daily inputs that research links to how you feel and function. A blood test ordered by a clinician is the only way to measure an actual hormone level. Stamnr is about understanding your own patterns, not your bloodwork.
The Climb is a single daily score built from four things you log: sleep, alcohol, training and stress. It puts your habits in one place and shows how they trend. It is a way to understand yourself, not a diagnosis or a health grade.
Yes, and the research is fairly settled. The size of the effect depends on the pattern rather than any one-off day, which is exactly why tracking the pattern tells you more than reacting to a single rough night.
Yes. Your logs are private to your account, and nobody else using Stamnr can see them. We do not sell your data, there is no advertising, and there are no third-party analytics or tracking tools in the app. Sensitive logs are processed only with your explicit consent, which you can withdraw at any time, and you can delete your account and its data whenever you want.

No. You can log all four inputs by hand in a few seconds a day. Connect Apple Health and Stamnr can pull in compatible data like sleep automatically, so that is one less thing to enter. No wearable required.
No. Stamnr does not change your hormones and does not claim to. It is a tracker. It shows you how your own inputs trend over time so you can understand your patterns. Anything promising to boost or restore testosterone is making a very different kind of claim than we are.
A day gives you a number. A week or two gives you a pattern, and the pattern is the useful part. Any single reading on its own tells you far less than the trend across your week.
Any man who wants to understand how his daily habits line up with how he feels and functions. It is built without judgement and without the fear-selling this space is known for. You do not need a problem to want to understand yourself.
No. Stamnr is for understanding your own patterns, not for diagnosing anything. If something feels off, or a change is sharp or persistent, that is a conversation for a doctor.
Yes. Log what is relevant to you. An input that does not apply to your life simply is not part of your picture.
The Climb is not a medical device. It does not diagnose or treat any condition.
