PeakLifeRx is a 503B procurement platform — tirzepatide availability changed in 2024
PeakLifeRx is a technology-enabled procurement platform connecting clinics to FDA-registered 503B outsourcing facilities. All GLP-1 products it lists come from 503B outsourcing facilities under cGMP standards — not patient-specific 503A compounders. After FDA removed tirzepatide from the shortage list in late 2024, 503B outsourcing facilities generally lost the shortage-list authority to compound tirzepatide for clinic stock. Whether PeakLifeRx's current 503B network still compounds tirzepatide and under what FDA pathway is not confirmed on peakliferx.com — ask directly before designing a program around the assumption.
This matters more for tirzepatide than for most molecules because the program economics are step-sensitive. Tirzepatide titrates across a wide dose range, and landed cost can shift at each step, so you need to model margin step by step — not off a blended quote from a catalog that may no longer be available. Fizy Health routes patient-specific tirzepatide to LegitScript-certified 503A partners, shows resolved per-vial cost at each step before checkout, and validates the entire cart before payment so a wrong vial for the step never becomes a paid rejection.
