How it works


Measure Your Baseline

Begin your journey with our at-home blood test that measures the 40+ biomarkers that drive your mental and physical performance. Then review your results with a Lifeforce medical doctor.


Start Your Membership

Kick off your Lifeforce Membership to get everything you need to power your peak, all in one trusted, convenient place. Your customized plan, written by a Lifeforce medical doctor, will include any recommended nutraceuticals, hormone optimization and peptides, and lifestyle changes — all based on your biology and goals.


Track Your Progress

Re-test your biomarkers every three months to track what’s changed, what’s improved, and what needs work. Your body is continuously evolving, and we’ll rigorously monitor each shift, big and small, so we can take action and keep you in your best state.


Review & Recalibrate

Together, we’ll review your results and fine-tune your program so you’re always making progress toward your goals. This is not a ‘one and done’ process — we’ll make sure the plan you’re on is continuously working for you.
