what is this item tested for? heavy metals? what type of impurities?

Hello, We test for many different heavy metals and potentially dangerous microbes as set fourth by FDA regulations. Hope this helps! -Caroline Double Wood Supplements

What is the difference between l-serine and the phosphatidyl serine, or benefits?

The question is highly technical and should be answered by the manufacture's technical staff or a certified organic chemist.

What agency is the third-party tester?

Hello, We are currently using Colmaric Analyticals for third party testing. Best Regards, -Reese Double Wood Supplements

Are the typical purity levels cited ? Thanks.

I see nothing on the web site guaranteeing purity. It only states that they have "third-party testing". That doesn't mean anything.
