Where White Label Rx fits in the 503A stack
Compounded medication for cash-pay clinics flows through a fixed chain: the prescriber writes the order, an telehealth platform routes it, a 503A compounding pharmacy makes it, and a carrier delivers it. White Label Rx occupies the ordering-platform layer — it does not hold a pharmacy license and does not compound, so questions about fill quality and certificates of analysis belong to the partner pharmacies, while questions about ordering, validation, and pricing visibility belong to the platform.
Fizy Health sits in the same layer but changes the timing of validation and pricing. It resolves per-vial 503A cost on each catalog and cart line before checkout, and it runs cart validation — SIGs, prescriber state licensure, and stock — before payment, so issues are caught before money moves rather than after a partner pharmacy rejects the order.
