max, do a search on the Avant board for this, there is quite a deal of useful info on filtering and adding various things, caffeine specifically.
I'm just about done so the verdict is:
It works the same IMO. No better, no worse.
Now from reading the literature it still looks as if Par's delivery is still superior (never really questioned that) but the results were about the same. Its tough to measure and get any type of accurate reading except for looking in the mirror and knowing what happened before, but I feel confident in saying it works around the same.
For answers to board issues, read the Suggestion and News forum at the bottom of the main page.
Thanks for the update bobo.
good to know, i got a bottle too, waiting to use it until after my T3 cycle though.. Think I should use it along with the T3?
