Do I need to get all these tests done?

No you don't have to. But they do allow me to give you better advice and suggestions. You'll get personalized advice and recommendations based on the test results. And you'll likely get better results along with that. So it's not mandatory because you can get started on the protocol without any tests at all. But it's definitely better for me to have more data. The more data, the better. So it's up to you. You can follow my supplement recommendations without any testing at all, and then see how that goes if you want.
