01
Comprehensive longevity intake
A detailed intake covering your health history, family longevity, current supplements, diet, sleep and exercise habits. Order baseline labs or upload your recent bloodwork — we need the full picture before building your protocol.
02
Get your personalized protocol
Your clinician designs a longevity stack based on your biological age, biomarkers and goals. Every protocol is evidence-informed and adjusted for contraindications, current medications and your personal risk profile.
03
Track, retest, optimize
Retest key biomarkers every 3–6 months. Your clinician reviews your progress, adjusts doses and introduces new interventions as the science evolves. Longevity is a marathon, not a sprint.
Clinician support,
not chatbots.
Message your clinician directly — ask about new research, biomarker interpretation, or protocol adjustments. Real doctors who stay current on longevity science, same-day replies.

Robert
"At 58, my biological age came back as 47 after nine months on the NAD+ and metformin protocol. The biomarker tracking makes all the difference — I can see the changes."
Elena
"I was spending $400/month on random longevity supplements with no plan. Rejuvyx gave me a clinician who actually reads the research and adjusts my stack based on my labs."
Thomas
"The NMN + resveratrol combo changed my energy levels in a way nothing else did. My HbA1c dropped from 5.8 to 5.2 in four months on metformin."
Sarah
"I love that my protocol evolves. When new research came out on spermidine, my clinician added it to my stack and explained exactly why."
Michael
"The quarterly biomarker panel is worth it alone. Seeing my inflammation markers, insulin sensitivity and NAD+ levels trend over time is incredibly motivating."
Jennifer
"Finally, a longevity approach that's not just 'take these pills and hope.' My clinician explains the mechanisms, the evidence and what to expect. It's real medicine."
