The better value

Of the stacks the Neurofeul is the best bang for the buck. Not sure how the smart caffeine is as a standalone

So far so good!

I only wish all the products were available to try. Been waiting for quite some time and finally settled on just trying what was available. Definitely has a nice pick me up. Seems like I ran out of the nuro before the smart caffeine. Maybe as a stack there should be equally 30 days worth In both.
