Why volume exposes single-compounder portal limits
Promise is a strong fit for telehealth brands that want white-label GLP-1 fulfillment from one 503A partner with COA documentation and a dedicated account manager. Peak day stress-tests a different dimension: how fast staff can move the due list through the portal, not how well Promise compounds a single order. Reorder tools help individual patients; they do not automatically batch fifty refills into one validated checkout.
Fizy Health targets peak prescriber ops. One cart holds the entire refill day across every assigned 503A partner, validation runs before one payment, pass-through per-vial cost supports mid-day patient pricing calls, and refill reminders smooth volume across the week. Clinics can keep Promise for white-label lines while using Fizy Health for batch checkout when the panel outgrows per-patient portal entry.
