What do underwriters check first for TB-500 merchant accounts?
TB-500 underwriting starts with product legality, MCC fit, processing history, chargeback exposure, and whether the merchant can prove fulfillment and customer consent. A clean file answers these questions before the acquirer asks for them, which reduces reserve pressure and review delays.
- Research-use-only labeling, product COAs, controlled-analogue screening, and no human-consumption claims.
- BPC-157, TB-500, SARMs, semaglutide analogues, and similar SKUs can trigger FDA/DEA-adjacent review.
- Domestic card processing is limited; offshore acquiring, crypto, and ACH often need to be layered.
