## What is PINN?

Pinn — Testosterone Tracking Made Simple

Pinn is built for people who want a reliable way to track testosterone injections without the clutter of a complicated health app. No endless menus. No confusing features you’ll never use. Just the information that actually matters.

Log each injection in seconds. Record what you took, how much, and where you administered it. Pinn keeps the timeline straight so you don’t have to wonder when your last dose was or when the next one should be.

Based on your injection history, Pinn estimates exogenous testosterone levels over time. If your protocol changes, Pinn forecasts how long it may take for your levels to stabilize again. It is designed to give you clarity so you can talk with your healthcare provider using data, not guesswork.

If you’ve ever tried to manage injections with a calendar app and felt like there had to be something better, Pinn was built for you. Honestly, it was built for that exact problem.

What Pinn helps you with:
• Tracking injection dates
• Recording compounds, dosage, and injection sites
• Visualizing estimated testosterone levels
• Seeing projected stabilization when your schedule or dosage changes
• Staying consistent and informed

Simple. Focused. Purpose-built.
That’s Pinn.
