Where VSDH sits in the stack — platform vs supplier
Compounded medication for cash-pay clinics flows through a fixed chain: prescriber, ordering layer, compounding supplier, carrier. VSDH occupies two roles depending on how you buy: as a white-label platform (apps, telemedicine, branded pharmacy) for operators launching a D2C brand, and as a supplier catalog that can also fulfill SKUs behind other ordering layers. Questions about fill quality and certificates of analysis belong to the compounders; questions about batch checkout, pre-pay validation, and margin visibility belong to the platform layer you choose.
Fizy Health sits in the clinic-first ordering layer. It resolves per-vial 503A cost on each catalog and cart line before checkout, runs cart validation — SIGs, prescriber state licensure, and stock — before payment, and batches an entire refill day into one cart. VSDH may still supply fulfillment behind Fizy Health on some SKUs; the compare is platform model vs clinic ops, not pharmacy quality.
