Starting a hormone or peptide therapy changes what's worth tracking on a lab report. This section covers the testing framework only, what to check before starting, what to retest and when, and how to read the direction of change, for the therapies with real guideline-backed monitoring markers.
Every page here is a baseline-then-retest testing framework for a specific therapy, built around the monitoring guidance published by the clinical bodies that oversee it.
This is different from FixFirst's Longevity blood markers section, which compiles the specific numeric targets individual experts like Peter Attia and Andrew Huberman cite in their own public protocols, attributed to the person, not a clinical guideline. This section instead follows the monitoring schedules published by medical societies and regulators for people already on, or considering, a specific therapy.
Every page states what to test and when to retest it, never dosing, titration schedules, or where to source a medication, those are questions for the prescribing physician overseeing the therapy. A page is marked medically reviewed only where the monitoring guidance is genuinely guideline-backed; where the evidence is thinner, that is stated plainly instead of implied.
Upload your blood report and FixFirst checks it against standard clinical thresholds, adjusted for your sex and context.
