GNC Is Trolling the NFL on Twitter for Rejecting Its Super Bowl Ad

Calls it the '#NoFunLeague'

After experiencing declining sales of late, GNC had been hoping to turn its fortunes around by investing an estimated $5 million in a 3o-second Super Bowl ad on Fox this year. However, the NFL had rejected the ad due to the league’s rules prohibiting banned substances, and GNC is on the list of brands players are prohibited from endorsing.
