Peak: Testosterone Tracker

Stop guessing your testosterone.

Peak helps you track your testosterone, symptoms, and daily habits - so you can understand what’s actually affecting your energy, mood, and performance.

No more isolated lab results.
No more confusion.
Just clear, data-driven insight into your body.


How it works

Each day, Peak combines your data into a clear picture:

• Testosterone labs → your baseline and trends
• Symptoms → energy, mood, sleep, recovery
• Daily patterns → habits that may influence your state

Then turns it into something useful:

→ What’s happening
→ What changed
→ What might be affecting you
