Vendor coverage
We track 120 vendors, last refreshed Sep 5, 2026. 20 have every size priced, 35 have everything published captured, 4 hide prices behind a wall, and 61 are still in capture.
A vendor can have every price captured and still be in progress when its vial sizes are not yet published or read.
When a vendor's site disappears, its prices stay as a dated historical record and its links are retired.
A wall is a result, not a gap. When a vendor hides prices, that fact is published here.

How these prices are collected
Prices on this site are read from vendor websites on the dates shown. A starting tag means the vendor publishes only a from price for that product. A wall means the vendor hides prices behind a login, and we publish that fact rather than hide the gap.
We report prices and never rate or score an offer. There is no value grade, no ranking of vendors by our opinion. A row carries its size, its price, its price per milligram, and any plain fact about the listing worth knowing.
When a vendor's site disappears, its rows stay in the tables as a dated record, drop out of every count, price range and ranking, and lose their links. Sixty days after a vendor's site disappears, its rows leave these tables and remain in our records.
Some vendors pay this site a commission when you buy through our links. Every one of those links is marked, and every vendor with that arrangement is labeled on the vendor page. Commissions never change the prices we show, the order of any table, a vendor's badge, or anything in the audit record. The data is collected the same way for every vendor, paid or not.
We accept no payment for coverage, placement, or ratings. Warning letters come from fda.gov. If a paying vendor earns a bad mark, the mark stays.
