Methylene blue sources with contaminant testing

I've been getting frequent questions about methylene blue sources, and have only just learned about a good option (thanks to Tyler for the discovery). It's the only product I know that's easily available to consumers, has a Certificate of Analysis, and is USP-grade. It's called Blue Brain Boost (formerly known as Synapse Nutrition) Methylene Blue. It's now only available in liquid form, with a choice of unflavored or blueberry-flavored. I did not find the blueberry flavoring to do much to mask the unpleasant taste.

There is a certificate of analysis available showing that it meets the USP standard. It also explains the solvents used (methylene chloride, chloroform, trichloroethylene, and 1,4-dioxane). The residual solvents are minimal, but if anyone knows of a source with gentler solvents, please let me know in the comments.

They are based in the US, but ship internationally.

Update for 9/8/2016: Health Natura has a lower-concentration (100mcg/drop) product. I haven't yet received a certficate of analysis for it though.
