What is vitamin B15?

Vitamin ? B-15 first appeared in the mid 1970's. The Russians had been using it as a performance enhancing supplement. As I remember it the main ingredient was called calcium pangamate. I believe it was derived from apricot pits. The new B-15 has everything in it from DMAE to procaine. I believe the one with procaine is closest to the one I took in the 70's. It was very good at letting you party all night.
