C4

So, C4 in the 'Greatest Energy Drinks of All Time' league is like that one overachiever in every class who won't let anyone forget they aced the test without studying. Seriously, you can’t ignore it. It’s like your gym buddy who screams on his last rep — necessary but mildly annoying. Fans swear it's the secret sauce to epic gym sessions, but let’s be real, half the thrill is just trying to pronounce the ingredients list without having a tongue twister session.
