Study Session E-Liquid contains a double strength shot of Focus Master and Caffeine Junkie (L-theanine and Caffeine) then we add to this a splash of our Tropic “Tangerine” Thunder handspun flavor for a mild hint of sweet.
L-theanine is the active ingredient in green tea that helps with focus, relaxation, and weight loss. It’s amazing stuff which is related to caffeine.
As with starting anything related to caffeine this is not recommended for those sensitive to caffeine like compounds. Please consult your physician before use.
Just some interesting information about L-theanine in it’s pure form:
Relaxation, rejuvenation, focus. The green tea energizes without draining, calms without putting to sleep, and motivates without the jitters. Although tea can have as much or more caffeine than some coffees, it doesn’t have the same “speedy” effect. (ref: 1,2)
The reason is its secret ingredient, L-theanine. Research shows that L-theanine neutralizes the speedy, jagged, bad effects of caffeine without reducing its mind-energizing, fat-burning features. (Ref:3,4)
