**Update** Killer Instinct pre workout is now in stock! Two flavors are available: Jolly Rancher and Cotton Candy. From the makers of Savage AF and Hardstyle, the Killer Instinct Pre Workout may drive you totally insane. Killer Instinct, which is due in by the end of this week, may be the strongest, fully dosed stimulant heavy pre workout ever made. Take a look at the label below... if you dare.
This Pre workout is for the truly hardcore and is NOT for beginners! We should have Killer Instinct by the end of this week and will update this post when it arrives. What do you think about this pre? Let us know in the comments section below.
