Where Promise's portal sits in the 503A stack
Compounded medications for cash-pay clinics move through a defined stack: the prescriber writes the order, a pharmacy compounds it, and a carrier ships it to the patient. Promise Pharmacy collapses the pharmacy and portal layers into one company — the portal is how clinics talk to the compounder that actually makes and ships the medication. That is structurally different from an ordering aggregator like Fizy Health, which sits above several LegitScript-certified 503A partners and routes each cart line after checkout.
Because Promise is both compounder and portal, questions about batch testing, USP 795/797/800 compliance, and state licensure are answered by Promise directly. Questions about batching refills across multiple compounders, pass-through pricing visible before checkout across partners, and pre-pay validation are where a multi-partner platform diverges from Promise's single-compounder model.
