How these quotes are selected
For each price basis, we prefer a recently checked manufacturer-direct quote, then a recently checked provider quote for that brand and formulation. Within each group, documented 30-day costs come first, lowest to highest. Quotes without a documented supply period have no cost rank. Older quotes appear as dated references only when no current quote is tracked. Providers may differ between entry and maintenance prices. Missing maintenance prices are never replaced with entry prices. Compounded products, combined brand quotes, and membership-only fees are excluded. Prices at different doses are not equivalent treatment costs; confirm supply length, eligibility, and added fees.
Every cash quote was checked on or after . Each quote shows its own check date. A quoted maintenance dose is not a dosing recommendation. Our methodology
