Earlier this week we got a look at Black Skull’s new and improved US version of its pre-workout Bone Crusher. The updated supplement features a lot more of everything and has actually been launched this weekend at the 2016 Olympia Expo. The Brazilian brand currently has its reformulated pre-workout on display and available for purchase in Las Vegas at the extremely low price of $10. We of course had to grab a tub with a deal like that, and definitely look forward to seeing how it compares to the disappointing original.
