I'm interested in these three.
Of the Pyritinol, are there any long time users here to share their experiences and take questions? Such as is it better than CDP Choline (assuming you've used both).
Is CDP Choline a good one or is it overhyped? Thinking of getting some.
And Pyridoxamine. Though not a noot, it is only put out by LEF. Any idea when other companies will be making some? Know of any other companies? I know it is a great AGE blocker as I've been keeping up with it for four years.
