Unfortunately the manufacturers of Piranha have not disclosed the levels of caffeine in their product.
Piranha comes in 4 varieties - Attack (fruit punch flavors), Shred (orange & pineapple), Frenzy (watermelon & Kiwi), & Sugar-free (low-cal).
Piranha Energy Drink is made by supplement company EAS. Caffeine content is concealed within an "energy blend". - although EAS claim that "One serving contains about as much caffeine as a cup of coffee" - which doesn't really tell us much at all (due to the variations in coffee brewing methods).
We would suggest Piranha contains around 80mg of caffeine
Piranha also contains bitter orange extract - another stimulant (contains synephrine).
DISCONTINUED It appears this product is no longer available.
