Testly

Testly builds personalized health products that start by listening.

Our first product, Testly Thyroid, exists for a specific reason.

Why we exist

There's a pattern in thyroid care. Someone feels off — tired, foggy, cold, heavier than they used to be. They go to their doctor. They get a TSH test. The result comes back “normal.” They leave the appointment feeling the same way they went in, only now with the added weight of being told there's nothing wrong.

The pattern repeats. For millions of people, for years at a time.

Testly exists because someone needs to build a product that takes those people seriously — that measures more than TSH, that adds context from genetics, that listens to what patients are actually experiencing, and that gives them a report they can bring back to the doctor to have a better conversation.

Medical Director

Dr. Timothy Graham, MD

Dr. Graham is what most thyroid patients have spent years looking for: a practicing endocrinologist who actually engages with the science, takes patients seriously, and doesn't reach for a prescription pad before the questions are answered.
