Redline RTD vs sugarfree RedBull

so with my little experiment, i found that the Redline "incinerator" stuff actually works better than RedBull. however the Redline stuff claims it's the ATP that is inside the drink. now, i know ATP gets dephosphorylated to produce energy and ADP. however, ATP is stored in cells. i don't see how digesting it would do anything since it would be broken down with stomach acid. but i did notice a significant increase in energy level without getting tired. i'll have to look into the biological reason why Redline works better. i'm intrigued.
