Anything I should add to this? Or remove? Maybe there are some contradictions? Would really appreciate any input on this:
Sulbutiamine
L-Theanine
Caffeine
Huperzine A
Phosphatidylserine
Alpha-GPC
DMAE
Vinpocetine
L-Tyrosine
Acetyl-L-Carnitine
Which of these ingredients do you regard as unnecessary?
