The honest summary
Function Health is a $499/year diagnostics subscription offering ~100 biomarkers tested twice yearly with AI-summarized insights. It is not a prescribing practice: members must take results elsewhere to act on them. REVRCEL covers a similar biomarker depth as part of coordinated care — physician interpretation, prescription protocols (peptides, hormones, GLP-1), and quarterly follow-up bloodwork are all delivered under one membership. The trade-off is straightforward: Function is the right choice if a member only wants tests and self-directed insight; REVRCEL is the right choice if a member wants the same diagnostic depth plus a clinician-prescribed plan to act on it.
