on to the formulation...
the main ingredient in focus factor is DMAE (which is also the cheapest ingredient)
it does contain vinpocetine, huperzine and bacopa- though amounts and percentages are not given.
It does not contain (as neurogenex does)
Galantamine- an upregulator of nicotinic receptors and an AChE-I
2-oxo-pyrrolidone (aka piracetam)- the most widely used nootropic in Europe.- the most prevalent but not main ingredient.
Neurogenex contains listed amounts all of which are pharmacologically significant.
