Is Dwayne "The Rock" Johnson doping? "If he's not, he's f*cking gifted," adds Martyn Ford

Dwayne Johnson, the iconic actor and former WWE wrestling star, boasts an imposing musculature that graces movie screens at the age of 51. But how did he achieve such an impressive body? Is it just hard work in the gym and a disciplined diet, or did banned substances help him?

Some, including UFC fighter Chael Sonnen, question the "naturalness" of Johnson's musculature. Sonnen, himself punished for doping, said in a podcast with Joe Rogan that at Johnson's age, such form is virtually impossible without steroids. "He's a liver king," Sonnen alluded to fitness influencer Brian Johnson, who previously denied steroids and then admitted to spending $11,000 a month on them.

Johnson has always denied steroid use, as has his family. He argues hard work and discipline. British bodybuilder Martyn Ford, while admiring Johnson's physique, wonders if he's really doping-free. "If it is, he's fucking gifted," he says.

Another critic is "king of Instagram" Dan Bilzerian, who calls Johnson fake and unhealthily large.

Only Johnson himself knows the truth. He shares footage of gym workouts and horrifying diets on the network. But these are only pieces of the puzzle, leaving the question of doping unanswered.
