Transparency is our score out of 100 for how much a vendor makes public about itself. It isn't a purity test.

Prices come from each vendor's public product feed and were last fetched Oct 15, 2026. They exclude shipping and discounts. $/mg uses the labeled amount, not measured content. $/mg marked * was converted to US dollars from the listed currency at the European Central Bank reference rate. A transparency score marked * is based on fewer than six checks; checks we couldn't complete score 0. How we compare prices.

Before you compare on price alone

A low price is only a bargain if the vial holds what the label says, and a high one doesn't prove quality: only an independent lab test shows what's in a vial. Check the vendor's latest batch certificate of analysis (how to read one).
