While performing this on an MTV awards show, the line "Feelin' good from the pills we took" was bleeped. As an subtle "screw you" to the show, they replaced "It's too late to turn back" with "It's too late to take pills" for the rest of the song. This incident is further evidence of why they never were as famous as they could have been.
The tune and chorus were lifted from their song "Portland."

"Kickstart My Heart" is about all the ways Motley Crue gets their blood flowing without drugs. It was inspired by their bass player Nikki Sixx, who claimed he had to be revived with a shot of adrenaline to the heart after an overdose.
