How to diligence Refill peptide pricing across your formulary
Start with the peptides you actually prescribe, not the full catalog Refill can access. Ask for written per-vial cost on your top five peptide SKUs by volume, confirm which 503A partner fulfills each, and ask whether meet-or-beat terms apply to peptides or only GLP-1s. Ask how multi-pharmacy routing affects cost when two peptides on the same patient order route to different partners. Ask whether software fee percentage applies uniformly across peptide order sizes.
Build a formulary spreadsheet: one row per peptide SKU with confirmed aggregate rate, software fee, and shipping. Weight rows by your actual monthly volume. A peptide program's margin is the weighted average of many lines, not the best-priced SKU in the demo.
