What a panel can measure.

The markers a hormone blood test commonly includes, in plain English. Which tests WeightGain offers will be announced before launch.

Total testosterone

All the testosterone in your blood: the part carried by proteins and the small part that circulates free. Levels run highest in the morning, which is why tests are usually drawn early.

For education only. It can’t tell you anything about your own levels.

We’re planning blood testing at labs across the country.
