How it works
How it works
Define goals
Caliber collects the context a clinician needs before a longevity decision is made.
Review labs and risks
The review can approve a path, ask follow-up questions, recommend labs, or point to local care.
Build a protocol
If treatment is appropriate, the plan explains format, monitoring, and fulfillment next steps.
Monitor tolerability and fit
Follow-up keeps side effects, response, refills, and changes from becoming disconnected.
Safety and availability
Eligibility is part of the experience.
Longevity protocols vary in evidence and availability. Caliber avoids guaranteed outcome claims and routes care through clinician review.
Caliber does not guarantee a prescription, specific medication, pharmacy availability, or outcome. A clinician may recommend another path when online care is not the right fit.
