Peptides require the full catalog tier
RxFul's tier structure is the first gate for peptide ordering. The Rx-GLP tier ($0/mo) explicitly excludes peptides and limits access to GLP products only. Sermorelin, NAD+, and the broader peptide menu require Rx-Bronze ($997/mo) or higher, which unlocks the full SKU catalog and cold-chain access. Beyond the tier question, peptide programs are wide: not every 503A pharmacy makes every peptide, so catalog breadth and multi-pharmacy routing matter as much as platform fees.
RxFul routes peptide orders through clinic-branded patient checkout with 3PL fulfillment on paid tiers. Fizy Health routes prescriber-side batch checkout with a searchable catalog across assigned compounders, catalog favorites for repeat SKUs, and per-vial cost visible on each line before payment.
