I just recently found a new source of sarcosine on the internet, this makes 3 sources that I know of in the world. You can buy it off of http://brainvitaminz.com/ . It’s probably the cheapest I’ve ever seen, 60g for $14. If you try it and it works let me know, I might start buying from them instead.
Good info I wish it would of worked longer than a week for me, I felt great when I first started to take it then it had no affect at all after awhile.
