I consume no caffeine regularily but today I decided to have a "Rockstar" drink to assay it's potential value.
I drank the whole thing, containing:
2000mg Taurine
400mg Guarana
100mg Inositol
400mg L-Carnitine
1000mg D Ribose
Assorted B vitamines and an unknown amount of Caffeine.
What interested me is that the clarity of mind and stimulation I felt some 3 hours after drinking felt much cleaner and more like an amphetamine than ordinary caffeine. The caffeine I felt right after drinking it and with the usual nervousness and giddiness of mind.
I'm curious which of the above ingredients play a role in the total effect of one of these beverages? Or rather, what would the effect be like if we removed the caffeine from the beverage, or the taurine, etc etc? Has anyone had plain guarana or taurine or inositol to compare to caffeine?
Any opinions?
