Function Health vs Marek Health

Vial Take

Both platforms share a focus on metabolic health and longevity protocols, and both carry clean federal records, so neither raises red flags on the regulatory side. The clearest difference you'll feel practically: Marek discloses its pharmacy partners (Empower and Fagron), so you can vet the supply chain before you commit, while Function keeps that side of the operation opaque, which is common for diagnostic platforms but still limits independent verification. Where they diverge in scope: Function goes deeper on lab panel breadth and is worth a look if diagnostics are your priority, while Marek's reach across 45 states and its TRT and peptide services make it the stronger fit if you're looking for ongoing treatment alongside the testing.
