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. 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).
